The
Internet is a worldwide collection of networks that links millions of
businesses, government offices, educational institutions, and individuals. Data
is transferred over the Internet using servers, which are computers that manage
network resources and provide centralized storage areas, and clients, which are
computers that can access the contents of the storage areas. The data travels
over communications lines. Each computer or
device on a communications line has a numeric address called an IP (Internet protocol) address, the text version of which is called a domain name. Every time you specify a domain name, a DNS (domain name system) server translates the domain name into its associated IP address, so data can route to the correct computer.

Understand Ways to Access the Internet
You
can access the Internet through an Internet service provider, an online service
provider, or a wireless service provider. An Internet service provider (ISP)
provides temporary Internet connections to individuals and companies. An online
service provider (OSP) also supplies Internet access, in addition to a variety
of special content and services. A wireless service provider (WSP) provides
wireless Internet access to users with wireless modems or Web-enabled handheld
computers or devices.
Employees
and students often connect to the Internet through a business or school network
that connects to a service provider. For home or small business users, dial-up
access provides an easy and inexpensive way to connect to the Internet. With
dial-up access, you use a computer, a modem, and a regular telephone line to
dial into an ISP or OSP. Some home and small business users opt for newer,
high-speed technologies. DSL (digital subscriber line) provides high-speed
connections over a regular copper telephone line. A cable modem provides
high-speed Internet connections through a cable television network.
Identify A URL
The
most widely used service on the Internet is the World Wide Web. The World Wide
Web (WWW or Web) consists of a worldwide collection of electronic documents
called Web pages. A browser is a software program used to access and view Web
pages. Each Web page has a unique address, called a URL (Uniform Resource
Locator) that tells a browser where to locate the Web page. A URL consists of a
protocol, domain name, and sometimes the path to a specific Web page or
location on a Web page. Most URLs begin with http://, which stands for
hypertext transfer protocol, the communications standard that enables pages to
transfer on the Web.
Recognize How Web Pages Use
Graphics, Animation, Audio, Video, and Virtual Reality
Many
exciting Web pages use multimedia. Multimedia refers to any application that
integrates text with one of the following elements: graphics, sound, video,
virtual reality, or other media elements.
A
graphic is a digital representation of information such as a drawing, chart, or
photograph. Two common file formats for graphical images on the Web are JPEG
(Joint Photographic Experts Group) and GIF (Graphics Interchange Format), which
use compression techniques to reduce the size of graphics files and thus speed
downloading.
Animation
is the appearance of motion created by displaying a series of still images in
rapid sequence. One popular type of animation, called an animated GIF, uses
computer animation and graphics software to combine several images into a
single GIF file.
Audio
is music, speech, or any other sound. A common format for audio files on the
Web is MP3, a popular technology that compresses audio. More advanced Web audio
applications use streaming audio, which transfers audio data in a continuous
and even flow, allowing users to listen to the sound as it downloads. Video
consists of full-motion images that are played back at various speeds. Video
files often are quite large in size. The Moving Pictures Experts Group (MPEG)
defines a popular video compression standard. Streaming video allows you to
view longer or live video images as they are downloaded.
Virtual
reality (VR) is the use of computers to simulate a real or imagined environment
that appears as a three-dimensional (3-D) space. A VR world is an entire 3-D
site that contains infinite space and depth.
Types of Web Pages
Advocacy
Web pages established for political candidates, called “e-campaigning,” has
become an important part of politics. Surveys show that more than 50 percent of
Internet users turn to the Web for information about political topics.
Business/marketing
Web pages used for shopping on the Internet are increasingly popular. In 1999,
17 million households shopped online. This figure is expected to grow to 49
million by 2004. A survey of back-to-school shoppers 34 years old and younger
showed that 17 percent planned to shop online for their children’s school
needs. Perhaps more significant, only 6 percent of surveyed shoppers reported
being uncomfortable with buying on the Internet.
Educational
institutions frequently publish informational Web pages. Today, most colleges
have Web sites that offer course descriptions, information about the student population,
and registration costs and deadlines. When shopping for college, surveys show
that high school seniors use the Web more than catalogs or guidebooks; about 80
percent of college-bound students start looking at college Web sites as
sophomores.
News
Web pages are the most popular Web sites among Americans with access to the
Internet. Although these Web sites often are associated with newspapers,
magazines, television stations, or radio stations, some are published only
online, without a related print or broadcast media.
Portal
Web pages often offer the following free services: search engine, news, sports
and weather, free personal Web pages, reference tools, shopping malls, e-mail,
instant messaging, newsgroups, and chat rooms. The dictionary defines a
“portal” as a door or gateway. Portal Web pages are gateways to a host of
services.
Personal
Web pages sometimes use Web cams to provide minute-by-minute views of life in a
dorm room, an apartment, a new-born baby’s crib, or even the inside of a
refrigerator. One devotee of these personal Web pages says visitors often
develop a sort of “relationship” with the Web page developer. Perhaps this
observation is true; some personal Web pages receive more than 1,000 hits a
day.
How Web Pages Use Multimedia
Multimedia
can bring a Web page to life, increase the types of information available on
the Web, expand on the Web’s potential uses, and make the Internet a more
entertaining place to explore. Because Web pages with multimedia take longer to
download, most browsers allow users to turn off some multimedia elements (such
as graphics) and show a text-only version, speeding the display of a Web page.
WEB PAGE DESIGNING: THE BASICS
When
it comes to running a successful business you need to use every marketing
avenue possible. One of the ways you can promote and market your business is by
having a web page. You can start by learning the basics of designing a web
page.
Web
page designing is fairly simple when you know the basics. You should approach
the project just like you would any other design project. Remember, that the
finished product needs to be informative and creative. The webpage will also
need to have a layout that is easy to navigate. When they are too complicated,
the attention of the user is lost. Users want to get information quickly and
easily. When designing your web page remember the design basics, space and
layout, colours and font and that ultimately you need to make sure that you are
presenting your business in the right way.
Before
you can become a master at web design you need to understand the basics. These
basics will be the foundation of any website. This includes:
Good
design. This is the first
step to think about before building a web page. Think about what you want your
it to say about your company and how you can accomplish that through the
overall design. It is important to understand how many pages you will need for
the overall website, which will be determined by the following points.
Structure. The structure of the web page and the design are
not the same thing. The design is the concept and the structure is the back
bone of the web page. This will include the navigation (which should be as
simple as possible for the user). In basic terms, the structure is the way in
which you choose to position different elements on the page. The way in which
you choose to display your content and how your users will interact with the
site will be determined by the structure. The main portions of your web page
are divided into three sections, these are the header, the footer and the
content.
Fonts. Choosing the correct font for your website can
be extremely difficult. Remember that the content on your page needs to be easy
to read, which is why a simple font is better. The content of your page will
determine whether you attract business or not. This means that the content
needs to be simple to read, easy to understand, informative and interesting.
When it comes to the headings and important titles you can choose a more
stylized font that will echo your businesses image.
Colours.
If you have a specific colour that represents your business, for example the
colours of your logo, these should be worked into the general colour scheme of
your website. Remember, that some colours do not work well on a web page, if your
colours are too bright or too dark it will be off putting to the user.
WEBSITE
A
website, also written as web site, or simply site, is a set of related web
pages served from a single web domain. A website is hosted on at least one web
server, accessible via a network such as the Internet or a private local area
network through an Internet address known as a Uniform resource locator. All
publicly accessible websites collectively constitute the World Wide Web.
A
webpage is a document, typically written in plain text interspersed with
formatting instructions of Hypertext Markup Language (HTML, XHTML). A webpage
may incorporate elements from other websites with suitable markup anchors.
WebPages
are accessed and transported with the Hypertext Transfer Protocol (HTTP), which
may optionally employ encryption (HTTP Secure, HTTPS) to provide security and
privacy for the user of the webpage content. The user's application, often a
web browser, renders the page content according to its HTML markup instructions
onto a display terminal.
The
pages of a website can usually be accessed from a simple Uniform Resource
Locator (URL) called the web address. The URLs of the pages organize them into
a hierarchy, although hyper linking between them conveys the reader's perceived
site structure and guides the reader's navigation of the site which generally
includes a home page with most of the links to the site's web content, and a
supplementary about, contact and link page.
Some
websites require a subscription to access some or all of their content.
Examples of subscription websites include many business sites, parts of news
websites, academic journal websites, gaming websites, file-sharing websites,
message boards, web-based email, social networking websites, websites providing
real-time stock market data, and websites providing various other services
(e.g., websites offering storing and/or sharing of images, files and so forth).
Overview
Websites
have many functions and can be used in various fashions; a website can be a
personal website, a commercial website, a government website or a non-profit
organization website. Websites can be the work of an individual, a business or
other organization, and are typically dedicated to a particular topic or
purpose. Any website can contain a hyperlink to any other website, so the
distinction between individual sites, as perceived by the user, can be blurred.
Websites
are written in, or dynamically converted to, HTML (Hyper Text Markup Language)
and are accessed using a software interface classified as a user agent. Web
pages can be viewed or otherwise accessed from a range of computer-based and
Internet-enabled devices of various sizes, including desktop computers,
laptops, PDAs and cell phones.
A
website is hosted on a computer system known as a web server, also called an
HTTP server. These terms can also refer to the software that runs on these
systems which retrieves and delivers the web pages in response to requests from
the website's users. Apache is the most commonly used web server software
(according to Netcraft statistics) and Microsoft's IIS is also commonly used.
Some alternatives, such as Lighttpd, Hiawatha or Cherokee, are fully functional
and lightweight.
Static
website
A
static website is one that has web pages stored on the server in the format
that is sent to a client web browser. It is primarily coded in Hypertext Markup
Language (HTML); Cascading Style Sheets (CSS) are used to control appearance
beyond basic HTML. Images are commonly used to effect the desired appearance
and as part of the main content. Audio or video might also be considered
"static" content if it plays automatically or is generally
non-interactive.
This
type of website usually displays the same information to all visitors. Similar
to handing out a printed brochure to customers or clients, a static website
will generally provide consistent, standard information for an extended period
of time. Although the website owner may make updates periodically, it is a
manual process to edit the text, photos and other content and may require basic
website design skills and software. Simple forms or marketing examples of
websites, such as classic website, a five-page website or a brochure website
are often static websites, because they present pre-defined, static information
to the user. This may include information about a company and its products and
services through text, photos, animations, audio/video, and navigation menus.
Static
web sites can be edited using four broad categories of software:
Text
editors, such as Notepad or Text Edit, where content and HTML markup are
manipulated directly within the editor program
WYSIWYG
offline editors, such as Microsoft FrontPage and Adobe Dreamweaver (previously
Macromedia Dreamweaver), with which the site is edited using a GUI and the
final HTML markup is generated automatically by the editor software
WYSIWYG
online editors which create media rich online presentation like web pages,
widgets, intro, blogs, and other documents.
Template-based
editors, such as Rapid Weaver and iWeb, which allow users to quickly create and
upload web pages to a web server without detailed HTML knowledge, as they pick
a suitable template from a palette and add pictures and text to it in a desktop
publishing fashion without direct manipulation of HTML code
Static
websites may still use server side includes (SSI) as an editing convenience,
such as sharing a common menu bar across many pages. As the site's behavior to
the reader is still static, this is not considered a dynamic site.
Dynamic
website
A
dynamic website is one that changes or customizes itself frequently and
automatically. Server-side dynamic pages are generated "on the fly"
by computer code that produces the HTML and CSS. There are a wide range of
software systems, such as CGI, Java Servlets and Java Server Pages (JSP),
Active Server Pages and ColdFusion (CFML) that are available to generate
dynamic web systems and dynamic sites. Various web application frameworks and
web template systems are available for general-use programming languages like
PHP, Perl, Python, and Ruby, to make it faster and easier to create complex
dynamic web sites.
A
site can display the current state of a dialogue between users, monitor a
changing situation, or provide information in some way personalized to the
requirements of the individual user. For example, when the front page of a news
site is requested, the code running on the web server might combine stored HTML
fragments with news stores retrieved from a database or another web site via
RSS to produce a page that includes the latest information. Dynamic sites can
be interactive by using HTML forms, storing and reading back browser cookies,
or by creating a series of pages that reflect the previous history of clicks.
Another example of dynamic content is when a retail website with a database of
media products allows a user to input a search request, e.g. for the keyword
Beatles. In response, the content of the web page will spontaneously change the
way it looked before, and will then display a list of Beatles products like
CDs, DVDs and books. Dynamic HTML uses JavaScript code to instruct the web
browser how to interactively modify the page contents.
One
way to simulate a certain type of dynamic web site while avoiding the
performance loss of initiating the dynamic engine on a per-user or
per-connection basis is to periodically automatically regenerate a large series
of static pages.
Multimedia
and interactive content.
Early
web sites had only text, and soon after, images. Web browser plug ins were then
used to add audio, video, and interactivity (such as for a rich Internet
application that mirrors the complexity of a desktop application like a word
processor). Examples of such plug-ins are Microsoft Silverlight, Adobe Flash,
Adobe Shockwave, and applets written in Java. HTML 5 includes provisions for
audio and video without plugins. JavaScript is also built into most modern web
browsers, and allows for web site creators to send code to the web browser that
instructs it how to interactively modify page content and communicate with the
web server if needed. (The browser's internal representation of the content is
known as the Document Object Model (DOM) and the technique is known as Dynamic
HTML.)
HTML AND PHP
HTML
or Hypertext Markup Language is the standard markup language used to create web
pages.
HTML
is written in the form of HTML elements consisting of tags enclosed in angle
brackets (like <html>). HTML tags most commonly come in pairs like
<h1> and </h1>, although some tags represent empty elements and so
are unpaired, for example <img>. The first tag in a pair is the start
tag, and the second tag is the end tag (they are also called opening tags and
closing tags).
The
purpose of a web browser is to read HTML documents and compose them into
visible or audible web pages. The browser does not display the HTML tags, but
uses the tags to interpret the content of the page. HTML describes the
structure of a website semantically along with cues for presentation, making it
a markup language rather than a programming language.
HTML
elements form the building blocks of all websites. HTML allows images and
objects to be embedded and can be used to create interactive forms. It provides
a means to create structured documents by denoting structural semantics for
text such as headings, paragraphs, lists, links, quotes and other items. It can
embed scripts written in languages such as JavaScript which affect the behavior
of HTML web pages.
Web
browsers can also refer to Cascading Style Sheets (CSS) to define the look and
layout of text and other material. The W3C, maintainer of both the HTML and the
CSS standards, encourages the use of CSS over explicit presentational HTML
PHP
PHP
is a server-side scripting language designed for web development but also used
as a general-purpose programming language. As of January 2013, PHP was
installed on more than 240 million websites (39% of those sampled) and 2.1 million
web servers. Originally created by Rasmus Lerdorf in 1994, the reference
implementation of PHP (the Zend Engine) is now produced by The PHP Group. While
PHP originally stood for Personal Home Page, it now stands for PHP: Hypertext
Preprocessor.
PHP
code can be simply mixed with HTML code, or it can be used in combination with
various templating engines and web frameworks. PHP code is usually processed by
a PHP interpreter, which is usually implemented as a web server's native module
or a Common Gateway Interface (CGI) executable. After the PHP code is
interpreted and executed, the web server sends resulting output to its client,
usually in form of a part of the generated web page – for example, PHP code can
generate a web page's HTML code, an image, or some other data. PHP has also
evolved to include a command-line interface (CLI) capability and can be used in
standalone graphical applications.
PHP
is free software released under the PHP License. PHP has been widely ported and
can be deployed on most web servers on almost every operating system and
platform, free of charge.
IMAGES
What
is the difference between JPEG, GIF and PNG?
JPEG
is a standardized image compression mechanism. JPEG is designed for compressing
either full-colour (24 bit) or grey-scale digital images of "natural"
(real-world) scenes.
It
works well on photographs, naturalistic artwork, and similar material; not so
well on lettering, simple cartoons, or black-and-white line drawings (files
come out very large). JPEG handles only still images, but there is a related
standard called MPEG for motion pictures.
JPEG
is "lossy", meaning that the image you get out of decompression isn't
quite identical to what you originally put in. The algorithm achieves much of
its compression by exploiting known limitation of the human eye, notably the
fact that small colour details aren't perceived as well as small details of
light-and-dark. Thus, JPEG is intended for compressing images that will be
looked at by humans.
A
lot of people are scared off by the term "lossy compression". But
when it comes to representing real-world scenes, no digital image format can
retain all the information that impinges on your eyeball. By comparison with
the real-world scene, JPEG loses far less information than GIF.
Quality
v Compression
A
useful property of JPEG is that the degree of lossiness can be varied by
adjusting compression parameters. This means that the image maker can trade off
file size against output image quality.
For
good-quality, full-color source images, the default quality setting (Q 75) is
very often the best choice. Try Q 75 first; if you see defects, then go up.
Except
for experimental purposes, never go above about Q 95; using Q 100 will produce
a file two or three times as large as Q 95, but of hardly any better quality.
If you see a file made with Q 100, it's a pretty sure sign that the maker
didn't know what he/she was doing.
If
you want a very small file (say for preview or indexing purposes) and are
prepared to tolerate large defects, a Q setting in the range of 5 to 10 is
about right. Q 2 or so may be amusing as "op art".
GIF
(Graphics Interchange Format)
The
Graphics Interchange Format was developed in 1987 at the request of CompuServe,
who needed a platform independent image format that was suitable for transfer
across slow connections. It is a compressed (lossless) format (it uses the LZW
compression) and compresses at a ratio of between 3:1 and 5:1
It
is an 8 bit format which means the maximum number of colours supported by the
format is 256.
There
are two GIF standards, 87a and 89a (developed in 1987 and 1989 respectively).
The 89a standard has additional features such as improved interlacing, the
ability to define one colour to be transparent and the ability to store
multiple images in one file to create a basic form of animation.
Both
Mosaic and Netscape will display 87a and 89a GIFs, but while both support
transparency and interlacing, only Netscape supports animated GIFs.
PNG
(Portable Network Graphics format)
In
January 1995 Unisys, the company CompuServe contracted to create the GIF
format, announced that they would be enforcing the patent on the LZW
compression technique the GIF format uses. This means that commercial
developers that include the GIF encoding or decoding algorithms have to pay a
license fee to CompuServe. This does not concern users of GIFs or
non-commercial developers.
However,
a number of people banded together and created a completely patent-free
graphics format called PNG (pronounced "ping"), the Portable Network
Graphics format. PNG is superior to GIF in that it has better compression and
supports millions of colours. PNG files end in a .png suffix.
PNG
is supported in Netscape 4.03 and above. For more information, try the PNG home
page.
When
should I use JPEG, and when should I stick with GIF?
JPEG
is not going to displace GIF entirely. For some types of images, GIF is
superior in image quality, file size, or both. One of the first things to learn
about JPEG is which kinds of images to apply it to.
Generally
speaking, JPEG is superior to GIF for storing full-color or grey-scale images
of "realistic" scenes; that means scanned photographs and similar
material. Any continuous variation in color, such as occurs in highlighted or
shaded areas, will be represented more faithfully and in less space by JPEG
than by GIF.
GIF
does significantly better on images with only a few distinct colors, such as
line drawings and simple cartoons. Not only is GIF lossless for such images,
but it often compresses them more than JPEG can. For example, large areas of
pixels that are all exactly the same color are compressed very efficiently
indeed by GIF. JPEG can't squeeze such data as much as GIF does without
introducing visible defects. (One implication of this is that large
single-color borders are quite cheap in GIF files, while they are best avoided
in JPEG files.)
Computer-drawn
images (ray-traced scenes, for instance) usually fall between photographs and
cartoons in terms of complexity. The more complex and subtly rendered the
image, the more likely that JPEG will do well on it. The same goes for
semi-realistic artwork (fantasy drawings and such). JPEG has a hard time with
very sharp edges: a row of pure-black pixels adjacent to a row of pure-white
pixels, for example. Sharp edges tend to come out blurred unless you use a very
high quality setting. Edges this sharp are rare in scanned photographs, but are
fairly common in GIF files: borders, overlaid text, etc. The blurriness is
particularly objectionable with text that's only a few pixels high. If you have
a GIF with a lot of small-size overlaid text, don't JPEG it.
Plain
black-and-white (two level) images should never be converted to JPEG; they
violate all of the conditions given above. You need at least about 16 grey
levels before JPEG is useful for grey-scale images. It should also be noted
that GIF is lossless for grey-scale images of up to 256 levels, while JPEG is
not.
GIF
Images
Use
GIF files for images that have a small, fixed number of colors. GIF files are
always reduced to no more than 256 unique colors. The compression algorithm for
GIF files is less complex than for JPG files, but when used on flat color
images and text it produces very small file sizes. The GIF format is not
suitable for photographic images or images with gradient colors. Because the
GIF format has a limited number of colors, gradients and photographs will end
up with banding and pixelation when saved as a GIF file.
JPG
Images
Use
JPG images for photographs and other images that have millions of colors. It
uses a complex compression algorithm that allows you to create smaller graphics
by losing some of the quality of the image. This is called a "lossy"
compression because some of the image information is lost when the image is
compressed.
The
JPG format is not suited to images with text, large blocks of solid color, and
simple shapes with crisp edges. This is because when the image is compressed
the text, color, or lines may blur resulting in an image that is not as sharp
as it would be saved in another format.
PNG
Images
The
PNG format was developed as a replacement for the GIF format when it appeared
that GIF images would be subject to a royalty fee. PNG graphics have a better
compression rate than GIF images which result in smaller images than the same
file saved as a GIF. PNG files offer alpha transparency as well as animation.
PNG
images, like GIFs, are not well suited to photographs. It is possible to get
around the banding issue that affects photographs saved as GIF files using true
colors, but this can result in very large images. PNG images are also not well
supported on older cell phones and feature phones.
Definition:
A
graphics format initially developed as an alternative to licensing issues with
GIF, PNG or Portable Network Graphic offers numerous advantages over GIF files.
Several years back there was limited support for PNG from both browsers and
graphics (and other) applications. That is not the case today. PNG is widely
supported.
PNG
(pronounced ping) is not just a replacement for GIF (or even JPG) images on the
Web. It also offers certain advantages over the TIFF format for print. Like
GIF, JPG, and TIF it is a bitmap or raster format.
Some
of the most touted advantages of PNG over other formats include:
·
Variable
transparency through alpha channels.
·
Gamma
correction that helps PNG looks better cross-platform than some other images.
·
Lossless,
patent-free compression that produces slightly smaller files than GIF
·
Interlacing/progressive
display.
·
Supports
48-bit true color, grayscale, and 8-bit color.
One
thing that GIF does that PNG does not is animation.
Question: Which Graphics File Format Is Best To Use When?
JPEG,
TIFF, PSD, PDD, BMP, PICT, PNG, and GIF Explained
Answer:
Here are some general guidelines:
·
If the images
are for the Web or online, use JPEG, PNG, or GIF.
·
If the images
are for print, use TIFF.
·
If you want to
keep a version that remains editable, choose your software's native file
format. (PSD for Photoshop, PSP for Paint Shop Pro, CPT for Corel Photo-Paint,
etc.)
Here
are brief descriptions of common graphics file formats, with links to follow
for more information:
JPEG - JPEG is best for photos when you need to keep
the file size small and don't mind giving up some quality for a significant
reduction in size. JPEG is not suitable for images with text, large blocks of
color, or simple shapes, because crisp lines will blur and colors can shift.
Only JPEG offers the options of Baseline, Baseline Optimized, or Progressive.
Baseline
(Standard) - This JPEG format is recognized by all Web browsers.
Baseline
Optimized - This JPEG format option provides optimized color and slightly
better compression. It is supported by all modern browsers, but was not
supported in the very earliest of Web browsers. It's your best choice for JPEG
files today.
Progressive
- Creates a JPEG file that displays gradually as it downloads, starting out
blocky, and gradually getting clearer as it downloads. It doesn't make the
image download any faster, but it can give the illusion of speed since the
blocky image is loaded right away on a slow connection. With the majority of
internet users on high speed connections today, Progressive JPEG is rarely
used.
TIFF - TIFF is good for any type of bitmap
(pixel-based) images. TIFF produces large files, but there is no loss in
quality. TIFF also preserves layers, alpha transparency, and other special
features when saved from Photoshop. The type of extra information stored with
TIFF files varies in different Photoshop versions, so consult Photoshop's help
for more information.
PSD,
PDD - PSD and PDD are
Photoshop's native format. Use PSD when you need to preserve layers,
transparency, adjustment layers, masks, clipping paths, layer styles, blending
modes, vector text and shapes, etc. The PDD extension was used in Adobe Photo
Deluxe (now discontinued), but it is identical to PSD format and the two can be
used interchangeably.
BMP - Use BMP for any type of bitmap (pixel-based)
images. BMPs are huge files, but there is no loss in quality. BMP has no real
benefits over TIFF, except you can use it for Windows wallpaper.
PICT - PICT is an old, Mac-only bitmap format, similar
to BMP for Windows. PICT is not often used today.
PNG - Use PNG when you need smaller file sizes with
no loss in quality. PNG files are usually smaller than TIFFs, in my experience.
PNG also supports alpha transparency (soft edges) and was developed to be a Web
graphics replacement for GIF. Note that if you want to retain full
transparency, you will need to save your PNG file as PNG-24 and not PNG-8.
PNG-8 is useful for reducing the file size of PNG files when you don't need
transparency, but it has the same color palette limitations as GIF files.
GIF - Use GIF for simple Web graphics having limited
colors. GIF files are always reduced to 256 unique colors or less and they make
very small, fast-loading graphics for the Web. GIF is great for Web buttons,
charts or diagrams, cartoon-like drawing, banners, and text headings. GIF is
also used for small, compact Web animations. GIF should rarely be used for
photos.
Biggest Mistakes in Web Design
1.
Believing People Care about You and Your Website.
Write
these two sentences where you can see them as you're working:
·
The only
reason my website exists is to solve my customers' problems.
·
What problems
does the page I'm looking at solve?
Nobody
Cares About You Or Your Site. Really, what visitors care about is solving their
problems. Now, most people visit a website to solve one or more of these four
problems:
·
They want/need
information
·
They want/need
to make a purchase / donation.
·
They want/need
to be entertained.
·
They want/need
to be part of a community.
Too
many organizations believe that a website is about opening a new marketing
channel, getting donations, promote a brand, or increase company sales by 15%.
No. It's about solving your customers' problems.
2. A Man From Mars Can't Figure Out What Your
Website Is About In Less Than Four Seconds. You should be able to look at the
home page of any site and figure out what the site is about in less than four
seconds. If you can't, the site is a failure.
3. Contrast. According to Wikipedia: "Contrast
is the difference in visual properties that makes an object (or its
representation in an image) distinguishable from other objects and the
background." According to Vincent Flanders: "Without proper contrast,
visitors to your site can't read the text and if they can't read it, they will
leave it."
4. Navigational Failure. All web navigation must
answer these questions:
Where
am I?
Where
have I been?
Where
can I go next?
Where's
the Home Page?
Where's
the Home Page?
Navigation
must be simple and consistent.
5. Your Website Lacks Heroin Content.
How
do you create Heroin Content? The answer depends on the likes and dislikes of
your audience. Remember, it's what your audience wants that counts. What I consider
Heroin Content is somebody else's Quinine Content.
Here
are some thoughts about web content.
·
Does your
content solve your customers' problems or does it create problems?
·
Does your
content match your audience's expectations?
·
Have you
determined the purpose of your site?
·
Do you know
your target audience?
Ask
yourself: "What content do I have that would cause anybody in their right
mind to visit my site a second, third, or fourth time?" This is extremely
important. You might con (seduce) someone to visit your site once, but why
would they want to come back a second, third, or fourth time? If you can't
answer this question, you really shouldn't have a web site.
·
Is the content
technically correct?
·
Does your
customer need to know the content you're presenting?
·
Is the content
current and updated frequently?
·
Can people
find the content they're looking for?
·
Does my site
have Heroin Content?
7.
Too Much Material on One Page.
Yes,
it's called a web page, but that doesn't mean you have to cram all your material
on one page — just like this page does <grin>.
It's
very easy to keep adding material to your home page until it gets out of
control.
With
so much content vying for attention, it’s difficult for the eyes to find the
focal point. People get confused and they leave. A long web page means you have
failed to organize your site properly — probably a combination of not planning
your site and poor navigation
Animation - Definition
The
word “animation” is from “animate,” which means to bring to life.
Thus
when a multimedia developer wants to bring an image to life, animation is used
Animation
is a graphic representation of drawings to show movement within those drawings.
A series of drawings are linked together and
usually photographed by a camera.
The
drawings have been slightly changed between individualized frames so when they
are played back in rapid succession (24 frames per second) there appears to be
seamless movement within the drawings.
Animation
is derived from the Latin word “anima”, the “animating principle”, the vital
force inside every living creature
It
is often used as a translation for the Greek word “psyche”, and related to the Christian
concept of soul.
Animation
is the technique of giving”soul” to inanimate objects, drawings.

12 Benefits of Having a Website
Some
of the goals that can be achieved by launching a website include the following:
1. Far Cheaper and Much More Flexible Than Print
Advertising
The
Internet is extremely different from print advertising in that space is cheap,
your advertisement is accessible for a longer period of time, the content can
be changed without having to ask someone to do it for you (if you use a content
management system) and you can potentially reach a wider audience.
This
is not to say that you should not use other forms of advertising at all You can use it to entice people to visit
your website and find out about your company and potentially open two-way
communication between the potential customer and a sales person.
2. Market Expansion
The
Internet has allowed businesses to break through the geographical barriers and
become accessible, virtually, from any country in the world by a potential
customer that has Internet access.
3. Diversify Revenue Streams
A
website is not just a medium for representation of your company, it is a form
of media from which everybody can acquire information. You can use this media
to sell advertising space to other businesses. A recent trend has risen where
businesses feature their very own directory of complimentary services, where
the visitor can search for information on a business that will enhance the use
of your service. The business sells complimentary businesses a listing in their
directory.
A
good example is a catering company featuring a directory with businesses such as
event co-coordinators, electronic equipment rental companies, etc.
4. 24 7 365
No
more turning customers away when its time to close shop, putting up a note
saying closed for public holiday , or
leaving an irritating message on your answering service specifying your trading
hours tell them to visit your website
for information they are looking for.
5. Offer Convenience
It
is far more convenient for a person to research a product on the Internet than
it is to get in a car, drive somewhere and look for or ask someone for
information on a product. Also, a potential customer won t have to judge a call
centre agent to determine whether he/she has their best interests in mind, or
just wants to make a sale. The potential customer can visit your website whenever
they like in their own privacy and comfort, without the stresses and
distractions that exist in the real world.
Your
website is a self-service medium for
example, instead of having to wait in a long cue to pay your TV License; you
can now do it electronically through the TV License website.
6. Add Value and Satisfaction
By
offering convenience, a point of reference and that touch of individualized
customer service, you ultimately add value to your offering and your customers
experience a higher level of satisfaction. Your website can add value in other
ways too, by featuring tips, advice and general interest content you can entertain
your customers. This will also help them remember you better.
7. Standardize Sales Performance
By
looking at which approached / pitches have worked in the past and those which
have not, you can produce the ultimate pitch and use it with your website, so
that you use it on every customer. No more training of sales people and waiting
for them to get a feel for your line of trade.
8. Improve credibility
A
website gives you the opportunity to tell potential customers what you are
about and why you deserve their trust and confidence. In fact, many people use
the internet for pre-purchase research so that they can determine for themselves
whether a particular supplier or brand is worthy of their patronage, and won t
take them for a ride.
The
Internet also allows for Viral Marketing
where your website visitors spread positive word-of-mouth about your
business - your customers do your marketing!
9. Promote your Brick n Mortar Presence
Getting
lost trying to find a place can be frustrating for a potential customer. You
can publish what they call a dummy map on your website, which shows directions
and landmarks graphically, and the potential customer can print it out when
looking for your Brick n Mortar premises.
You
might advertise a promotion on your website encouraging the visitor to visit
your Brick n Mortar premises (e.g. At a
branch nears you! ).
Also,
if you recently moved to a new location, you will have to wait for the next
'phone directory to come out before people figure out where you currently are.
Because a website is flexible you can
change the content as you like you can
change you contact details instantly and lower the risk of losing customers
when moving to a new location.
10. Growth Opportunity
A
website serves as a great place to refer potential investors to, to show them
what your company is about, what it has achieved and what it can achieve in
future.
11. Two-Way Communicative Marketing
Customers
can quickly and easily give feedback on your product and/or marketing approach.
12. Cheap Market Research
You
can use features on your website such as visitor polls, online surveys and your
website statistics to find out what your customers like more and how they feel
about certain aspects of your business to determine how you can improve your
product and the way you do business.
