Accessing Information Using Computer Systems


[attachment=33025]

INTRODUCTION

With the introduction of the Internet and the World
Wide Web, students are able to access information
faster and more efficiently using modern Computer
Systems. In the past, one had to visit national and
school libraries and spend large amounts of time
accessing information. Presently any individual can
quickly access, save and print information from any
location. One can access the internet from Cyber
Cafes, schools, mobile phones, at home and even at
modern libraries through internet service providers
and telecommunication links. Apart from the internet,
information e.g. encyclopedias, tutorials and documentaries
can be accessed from Compact Discs which
are read from computer systems.

What is the Internet?

The Internet is a network of networks, linking
computers to computers sharing the TCP/IP protocols.
Each runs software to provide or “serve”
information and/or to access and view information.
The Internet is the transport vehicle for the
information stored in files or documents on another
computer. It can be compared to an international
communications utility servicing computers. The
Internet itself does not contain information. It is a
slight misstatement to say a “document was found
on the Internet.” It would be more correct to say it
was found through or using the Internet. What it
was found in (or on) is one of the computers linked
to the Internet.

What is the World Wide Web and what
makes it work?


The WWW incorporates all of the Internet services
above and much more. You can retrieve documents,
view images, animation, and video, listen to sound
files, speak and hear voice, and view programs that
run on practically any software in the world, providing
your computer has the hardware and software to do
these things.
When you log onto the Internet using Netscape
or Microsoft’s Internet Explorer or some other
browser, you are viewing documents on the World
Wide Web. The current foundation on which the
WWW functions is the programming language called
HTML. It is HTML and other programming imbedded
within HTML that make possible Hypertext.
Hypertext is the ability to have web pages containing
links, which are areas in a page or buttons or graphics
on which you can click your mouse button to retrieve
another document into your computer. This “clickability”
using Hypertext links is the feature which is
unique and revolutionary about the Web.

What is a Browser? What is Netscape and
Internet Explorer?


A browser is a computer program that resides on
your computer enabling you to use the computer to view
WWW documents and access the Internet taking advantage
of text formatting, hypertext links, images,
sounds, motion, and other features. Netscape and
Internet Explorer are currently the leading “graphical
browsers” in the world (meaning they facilitate
the viewing of graphics such as images and video
and more). There are other browsers (e.g., Mozilla
Firefox, Opera).

Information

From the list of numbered headings displayed, we
can select any one and view the contents by positioning
the arrow, using the mouse and double clicking. Single
clicking in the mouse chooses the heading and double
clicking opens the file.
In our Example, double clicking on: Heading
number 2 – Doing Business as a sole Proprietor will
produce the following information
The sole proprietorship is perhaps the most
common form of business ownership. Conducting
business as a sole proprietor has distinct advantages
and disadvantages. You should be aware of these
characteristics, as they can have a significant impact
on your business. Please note that brief references
appear in this article to corporations, another form
of business ownership.

What is a sole proprietorship?

A sole proprietorship is an unincorporated business
owned by one person (hence, the term sole). The
owner of a sole proprietorship is known as a sole
proprietor. If you conduct your business through a
corporation, your business will not be a sole proprietorship.
If you share ownership of your business with
someone else, including your spouse, your business
will not be a sole proprietorship.
Please note that if the information obtained is
insufficient or irrelevant, the present file can be closed
and another heading selected, viewed and printed. This
process can be repeated many times as one wishes.
