Computer Basics

In a relatively short time span since its invention, computer has affected many areas of our lives. For example, computers help in controlling our mobiles, act as challenging adversaries in electronic games, make possible very sophisticated medical diagnostic tools such as CAT Scanner, and even act as an ideal match-maker through computerized dating services. 

But most important, computers have a tremendous impact on the way information is processed within organizations today. Although information has been processed manually throughout history, modern management information systems would not be possible without the computers.

Computers have completely altered the structure of business. Large volumes of accounting and record keeping data can be manipulated, organized, stored, retrieved, and used for scientific purposes. Bills and statements can be processed and sent to customers in much less time and much less effort than that would be required for the same processes if carried out manually. Financial projections are made with greater ease, as the computers help managers to organize and manipulate financial data .

In manufacturing industries , computers direct production , guide machine tools, control quality, design parts, and monitor inventories.

In modern offices, word processing saves time for the employees at all levels of organization and helps insure drafting accurate letters, report and memos. Automated filing uses far less storage space than endless stacks of paper and enables workers to retrieve documents rapidly when they are needed. With more organized and consistent file systems, data management becomes more efficient.

Modern banking would be impossible without the computers. More than $500 billion a day is shifted electronically in the United States, and around $ 1000 billion globally. 

It would be difficult for the federal governments to function without computers. Economic and demographic statistics can be more easily collected, analyzed, and reported.

The Internal Revenue Service can keep better tax records. Computers aid law enforcement officials in monitoring laws and rapidly communicating information related to their duties. National defence systems are guided and managed by computer systems.

Global communication has been facilitated by the electronic transmission of data that connects individuals , regardless of geographic location, almost instantaneously.
