What is a the Internet?
A global network connecting millions of computers in more than 100
countries, allowing the exchange of data, news and opinions.
The Internet originated in 1969, in the midst of the Cold War,
as a "nuke-proof" communications network for the U.S.
defense department.
Now, however, it consists of countless networks and computers across
the world that allow millions of people to share information.
What is HTML?
Short for HyperText Markup Language, the authoring language used
to create documents on the World Wide Web. HTML defines the structure
and layout of a web document by using a variety of tags and attributes.
What is a Domain Name?
Put simply a domain name is the part of an internet address after
the 'www.'. It can be used as part of your web address or your email
address or both.
Your own domain name makes it easy for others to remember your
web/email address, and easier for you to tell others about your
address.
You can have multiple domain names linking to a web
site. For example smithandgagganau.co.uk who manufacture porcelain
could also have an additional generic domain name such as porcelain.co.uk.
What is a Browser?
If you can read this, it's highly likely that you're using a web
browser as your interface to the World Wide Web. It interprets hypertext
links and lets you view sites and navigate from one Internet node
to another. Among the companies that produce browsers are NCSA Mosaic,
Netscape and Microsoft, as well as commercial services like CompuServe,
Prodigy, and America Online.
What is a URL?
URLs are the Internet equivalent of addresses. The first part of
the address indicates what protocol to use and the second part specifies
the IP address or the domain name where the resource is located.
What is a Hyperlink?
An element in an electronic document that links to another place
in the same document or to an entirely different document. Typically,
you click on the hyperlink to be taken somewhere else. Hyperlinks
are the most essential ingredient of all hypertext systems, including
the World Wide Web.
What is a Search Engine?
A program that searches for specified keywords and returns a list
of the documents where the keywords were found.
.
What is a Server?
The business end of a client/server setup, a server is usually a
computer that provides the information, files, Web pages, and other
services to the client that logs on to it. (The word 'server' is
also used to describe the software and operating system designed
to run server hardware).
What is E-commerce?
Short for electronic commerce. Conducting business on-line. This
includes, for example, buying and selling products with digital
cash and via Electronic Data Interchange (EDI).
What is Spam?
Electronic junk mail or junk newsgroup postings. It is generally
e-mail advertising sent to a mailing list or newsgroup.
In addition to wasting people's time with unwanted
e-mail, spam also eats up a lot of network bandwidth. Consequently,
there are many organizations, as well as individuals, who have taken
it upon themselves to fight spam with a variety of techniques. But
because the Internet is public, there is really little that can
be done to prevent spam. However, some private online service, such
America Online, have instituted policies to prevent spammers from
spamming their subscribers.
What is a Cookie?
A message given to a browser by a server and sent back
to the server each time the browser then requests a page from that
server.
The main purpose of cookies is to identify users and
possibly prepare customized web pages for them. When you enter a
web site using cookies, you may be asked to fill out a form providing
such information as your name and interests. The next time you go
to the same web site, your browser will send the cookie to the web
server. So, for example, instead of seeing just a generic welcome
page you might see a welcome page with your name on it.
What is an Intranet?
Usually owned and managed by a corporation, an Intranet
enables a company to share its resources with its employees without
confidential information being made available to everyone with Internet
access.
What is the Web Browser Cache?
A web browser cache stores the pages, graphics, sounds,
and URLs of online places you visit on your hard drive; that way,
when you go back to the page, everything doesn't have to be downloaded
all over again. Since disk access is much faster than Internet access,
this speeds things up.
