According to a quotation from searchwebservices.techtarget.com [10], technically, a
Web browser is a client program that uses the Hypertext Transfer Protocol (HTTP) to
make requests of Web servers throughout the Internet on behalf of the browser user.
Therefore, web browser
is a program
used by
us
to
look at and
interact
with all
the
information on the World Wide Web.
According
to
a
quotation
from
searchwebservices.techtarget.com [10], a commercial
version of the original browser, Mosaic, is in use. Many of the user interface features in
Mosaic, however, went into the first widely used browser, Netscape Navigator. Microsoft
followed
with
its
Microsoft
Internet
Explorer.
Today,
these
two
browsers
are
the
only
two browsers that the vast majority of Internet users are aware of. Although the online
services,
such
as
America
Online,
originally
had
their
own
browsers,
virtually
all
now
offer the Netscape or Microsoft browser. Lynx is a text-only browser
for UNIX shell and
VMS users. Another recently offered and well-regarded browser is Opera.
2.3.3 Hyper Text Markup Language (HTML)
According to Marty [1],
web pages are
mostly created by
using Hyper Text Markup
Language
(HTML),
which
lets
you
mix
regular
text
with
“markup”
tags
describing
the
text. These tags can describe the appearance (display in red) or layout (arrange the
following
in a 3-row, 4-column table) of
the
text, but
the
majority simply
describes
the
content
(this
is a
main
heading) and
leaves
many of the appearance and
layout decisions
to the browser. The following is an example showing the HTML document used to create
the webpage shown in Figure.
