"Search Engine Optimization." Just about every
Webmaster wants his or her site to appear in the
top listings of all the major search engines. Say,
for example, that John runs an online shoe store.
He wants his site to show up in the top few
listings when someone searches for “basketball
shoes." Then he gets more leads from search
engines, which means more traffic, more sales,
and more money. The problem is that there are
thousands of other shoe sites, whose
Webmasters are hoping for the same thing.
That's where search engine optimization, or SEO,
comes in.
Social media is a collection of Internet-based communities that allow users to interact
with each other online. This includes web forums, wikis, and user-generated
content websites. However, the term is most often used to describe popular social
networking websites, which include the following:
Data streaming, commonly seen in the forms
of audio and video streaming, is when a
multimedia file can be played back without
being completely downloaded first. Most
files, like shareware and software updates
that you download off the Internet, are not
streaming data. However, certain audio
and video files like Real Audio and
QuickTime documents can be streaming
files, meaning you can watch a video or
listen to a sound file while it's being
downloaded to your computer. With a fast
Internet connection, you can actually
stream live audio or video to your
"Internet trolls" are real and cause real
problems. In computing, the term "troll"
refers to a person who posts offensive,
incendiary, or off topic comments online.
These comments may appear in Web
forums, on Facebook walls, after news
articles or blog entries, or in online chat
rooms. Trolls stir up emotions from other
commenters, creating unnecessary
arguments for the sake of amusement.
"Wide Area Network." It is similar to a
Local Area Network (LAN), but it's a
lot bigger. Unlike LANs, WANs are
not limited to a single location. Many
wide area networks span long
distances through telephone lines,
fiber-optic cables, or satellite links.
They can also be composed of
smaller LANs that are
interconnected. The Internet could
be described as the biggest WAN in
the world.
Web 2.0 is term that was introduced in 2004 and refers to the second generation of
the World Wide Web. Like software, the new generation of the Web includes new
features that were not available in the past. However, Web 2.0 does not refer to a
specific version of the Web, but rather a series of technological improvements.
Some examples of features considered to be part of Web 2.0 are listed below:
Blogs - also known as Web logs, these allow users to post thoughts and updates about their life on the Web.
Wikis - sites like Wikipedia and others enable users from around the world to add and update online content.
Social networking - sites like Facebook and MySpace allow users to build and customize their own profile.
Web applications - new applications make it possible to run programs directly in a Web browser.

Web design is the process of creating websites. It
encompasses several different aspects, including
webpage layout, content production, and graphic
design. While the terms web design and web
development are often used interchangeably, web
design is technically a subset of the broader
category of web development.
Websites are created using a markup language called
HTML. Web designers build webpages using
HTML tags that define the content and metadata of
each page. The layout and appearance of the
elements within a webpage are typically defined
using CSS, or cascading style sheets. Therefore,
most websites include a combination of HTML and
CSS that defines how each page will appear in a
"Cascading Style Sheet" Cascading
style sheets are used to format the
layout of Web pages. They can be
used to define text styles, table sizes,
and other aspects of Web pages that
previously could only be defined in a
page's HTML.
CSS helps Web developers create a
uniform look across several pages of
a Web site. Instead of defining the
style of each table and each block of
text within a page's HTML, commonly
used styles need to be defined only
once in a CSS document.
The webmaster is the person in charge of maintaining a
Web site. The jobs of a webmaster include writing HTML
for Web pages, organizing the Web site's structure,
responding to e-mails about the Web site, and keeping
the site up-to-date.
A wiki is a Web site that allows users
to add and update content on the
site using their own Web browser.
This is made possible by Wiki
software that runs on the Web
server. Wikis end up being created
mainly by a collaborative effort of
the site visitors.
A great example of a large wiki is the Wikipedia,
a free encyclopedia in many languages that
anyone can edit. The term "wiki" comes from
the Hawaiian phrase, "wiki wiki," which means
"super fast." I guess if you have thousands of
users adding content to a Web site on a regular
basis, the site could grow "super fast."
WordPress is a free software used to build websites. Its
ease of use and unique blogging features have
helped it become the most popular blogging tool on
the web.
WordPress provides a web-based user interface for
designing, publishing, and updating websites. Instead
of writing HTML, you can simply choose one of many
different website templates or "themes" that has a
design you like. You can then modify the layout and
build a custom navigation bar. Once the site layout is
complete, you can use WordPress' online interface to
create individual pages. Each page may include
formatted text, links, images, and other media. You
can publish completed webpages or blogs by simply
clicking the Publish button.
