The
Internet,
sometimes
called simply
"the
Net," is
a worldwide
system of
computer
networks - a
network of
networks in
which users at
any one
computer can,
if they have
permission,
get
information
from any other
computer (and
sometimes talk
directly to
users at other
computers).
It was
conceived by
the Advanced
Research
Projects
Agency (ARPA)
of the U.S.
government in
1969 and was
first known as
the ARPANET.
Today, the
Internet is a
public,
cooperative,
and
self-sustaining
facility
accessible to
hundreds of
millions of
people
worldwide.
What
is World Wide
Web (WWW) ?
World
Wide Web is
the most
widely used
part of the
Internet;
often
abbreviated
"WWW"
or called
"the
Web". Its
outstanding
feature is
hypertext, a
method of
instant
cross-referencing.
In most Web
sites, certain
words or
phrases appear
in text of a
different
color than the
rest; often
this text is
also
underlined.
When you
select one of
these words or
phrases, you
will be
transferred to
the site or
page that is
relevant to
this word or
phrase.
Sometimes
there are
buttons,
images, or
portions of
images that
are "clickable."
If you move
the pointer
over a spot on
a Web site and
the pointer
changes into a
hand, this
indicates that
you can click
and be
transferred to
another site.
What
is a URL ?
A URL
(Uniform
Resource
Locator) is
the address of
a file
(resource)
accessible on
the Internet.
The type of
resource
depends on the
Internet
application
protocol.
Using the
World Wide
Web's
protocol, the
Hypertext
Transfer
Protocol
(HTTP) , the
resource can
be an HTML
page (like the
one you're
reading), an
image file, a
program such
as a common
gateway
interface
application or
Java applet,
or any other
file supported
by HTTP. The
URL contains
the name of
the protocol
required to
access the
resource, a
domain name
that
identifies a
specific
computer on
the Internet,
and a
hierarchical
description of
a file
location on
the computer.
On the Web ,
an example of
a URL is: http://www.nns.com.np
What
is a Web
(Internet)
Browser?
A Web
(Internet)
Browser is a
software
application
that allows
you to browse
the World Wide
Web. An
Internet
Browser
basically
interprets the
programming
language
(HTML) of the
internet into
the words and
graphics that
you see when
viewing a web
page. Some of
the popular
browsers are
Internet
Explorer,
Netscape
Navigator,
Opera etc.
What
is a proxy
server?
Proxy
server is
meant to
improve the
access speed
of Internet.
A proxy server
improves
browsing
performance by
functioning as
a caching
server. Using
its cached web
pages, the
proxy server
serves
already-accessed
web pages to
requesting
users without
requiring
outside access
to the
Internet.
