Computers are capable of doing more things every year. There are many advantages to
knowing how to use a computer, and it is important that everyone know how to use them
properly. Using the information I have gathered, and my own knowledge from my 12 years of
computer experience, I will explain the many advantages of owning a computer and knowing
how
to use a PC and I will attempt to explain why you should purchase a computer and learn how
to
use one properly.
Webster's New World Compact Dictionary defines a computer as "an electronic machine
that
performs rapid, complex calculations or compiles and correlates data"
("Computer."). While this
definition gives one a very narrow view of what a computer is capable of doing, it does
describe
the basic ideas of what I will expand upon. We have been living through an age of
computers for a
short while now and there are already many people world wide that are computer literate.
According to Using Computers: A Gateway to Information World Wide Web Edition, over 250
million Personal Computers (PC's) were in use by 1995, and one out of every three homes
had a
PC (Shelly, Cashman,& Waggoner, 138).
Computers are easy to use when you know how they work and what the parts are. All
computers perform the four basic operations of the information processing cycle: input,
process,
output, and storage. Data, any kind of raw facts, is required for the processing cycle to
occur.
Data is processed into useful information by the computer hardware. Most computer systems
consist of a monitor, a system unit which contains the Central Processing Unit (CPU), a
floppy-disk drive, a CD-ROM drive, speakers, a keyboard, a mouse, and a printer. Each
component takes a part in one of the four operations.
The keyboard and mouse are input devices that a person uses to enter data into the
computer.
From there the data goes to the system unit where it is processed into useful information
the
computer can understand and work with. Next the processed data can be sent to storage
devices
or to output devices. Normally output is sent to the monitor and stored on the hard-disk
or to a
floppy-disk located internal of the system unit. Output can also be printed out through
the printer,
or can be played through the speakers as sound depending on the form it takes after it is
processed.
Once you have grasped a basic understanding of the basic parts and operations of a
computer,
you can soon discover what you can do with computers to make life easier and more
enjoyable.
Being computer literate allows you to use many powerful software applications and
utilities to do
work for school, business, or pleasure. Microsoft is the current leading producer of many
of these
applications and utilities.
Microsoft produces software called operating systems that manage and regulate the
information processing cycle. The oldest of these is MS-DOS, a single user system that
uses typed
commands to initiate tasks. Currently Microsoft has available operating systems that use
visual
cues such as icons to help enter data and run programs. These operating systems are ran
under
an environment called a Graphical User Interface (GUI's). Such operating systems include
Windows 3.xx, Windows 95, and Windows NT Workstation. Windows 95 is geared more for use
in the home for productivity and game playing whereas Windows NT is more business
orientated.
The article entitled "Mine, All Mine" in the June 5, 1995 issue of Time stated
that 8 out of 10
PC's worldwide would not be able to start or run if it were not for Microsoft's operating
systems
like MS-DOS, Windows 95, and Windows NT (Elmer-Dewitt, 1995, p. 50).
By no means has Microsoft limited itself to operating systems alone. Microsoft has also
produced a software package called Microsoft Office that is very useful in creating
reports, data
bases, spreadsheets, presentations, and other documents for school and work. Microsoft
Office:
Introductory Concepts and Techniques provides a detailed, step-by-step approach to the
four
programs included in Microsoft Office.
Included in this package are Microsoft Word, Microsoft Excel, Microsoft Access, and
Microsoft PowerPoint. Microsoft Word is a word processing program that makes creating
professional looking documents such as announcements, resumes, letters, address books, and
reports easy to do. Microsoft Excel, a spreadsheet program, has features for data
organization,
calculations, decision making, and graphing. It is very useful in making professional
looking
reports. Microsoft Access, a powerful database management system, is useful in creating
and
processing data in a database. Microsoft PowerPoint is ". . a complete presentation
graphics
program that allows you to produce professional looking presentations" (Shelly,
Cashman, &
Vermaat, 2). PowerPoint is flexible enough so that you can create electronic
presentations,
overhead transparencies, or even 35mm slides.
Microsoft also produces entertainment and reference programs. "Microsoft's Flight
Simulator
is one of the best selling PC games of all time" (Elmer-Dewitt, 50). Microsoft's
Encarta is an
electronic CD-ROM encyclopedia that makes for a fantastic alternative to 20 plus volume
book
encyclopedias. In fact, it is so popular, it outsells the Encyclopedia Britannica. These
powerful
business, productivity, and entertainment applications are just the beginning of what you
can do
with a PC.
Knowing how to use the Internet will allow you access to a vast resource of facts,
knowledge,
information, and entertainment that can help you do work and have fun. According to
Netscape
Navigator 2 running under Windows 3.1, "the Internet is a collection of networks,
each of which
is composed of a collection of smaller networks" (Shelly, Cashman, & Jordan, N2).
Information
can be sent over the Internet through communication lines in the form of graphics, sound,
video,
animation, and text. These forms of computer media are known as hypermedia. Hypermedia is
accessed through hypertext links, which are pointers to the computer where the hypermedia
is
stored. The World Wide Web (WWW) is the collection of these hypertext links throughout the
Internet. Each computer that contains hypermedia on the WWW is known as a Web site and has
Web pages set up for users to access the hypermedia. Browsers such as Netscape allow
people to
"surf the net" and search for the hypermedia of their choice.
There are millions of examples of hypermedia on the Internet. You can find art, photos,
information on business, the government, and colleges, television schedules, movie
reviews, music
lyrics, online news and magazines, sport sights of all kinds, games, books, and thousands
of other
hypermedia on the WWW. You can send electronic mail (E-Mail), chat with other users around
the world, buy airline, sports, and music tickets, and shop for a house or a car. All of
this, and
more, provides one with a limitless supply of information for research, business,
entertainment, or
other personal use. Online services such as America Online, Prodigy, or CompuServe make it
even easier to access the power of the Internet. The Internet alone is almost reason
enough to
become computer literate, but there is still much more that computers can do.
Knowing how to use a computer allows you to do a variety of things in several different
ways.
One of the most popular use for computers today is for playing video games. With a PC you
can
play card games, simulation games, sport games, strategy games, fighting games, and
adventure
games. Today's technology provides the ultimate experiences in color, graphics, sound,
music,
full motion video, animation, and 3D effects. Computers have also become increasingly
useful in
the music, film, and television industry. Computers can be used to compose music, create
sound
effects, create special effects, create 3D life-like animation, and add previous existing
movie and
TV footage into new programs, as seen in the movie Forrest Gump. All this and more can be
done with computers.
There is truly no time like the present to become computer literate. Computers will be
doing
even more things in the future and will become unavoidable. Purchasing and learning about
a new
PC now will help put PC's into the other two-thirds of the homes worldwide and make the
transition into a computer age easier.
