Role of Computers in many Areas of Society

In Business

The use of computers in business is very common. Because microcomputers are now so inexpensive, small enterprises also utilize computers. Business organizations need to handle many information and figures. Many businesses have begun to utilize computers to calculate wages, identify things sold and still in stock, and create, transmit, or receive corporate statements, letters, invoices, and other papers.

It was stated that computers and office technology could assist other managers, clerks, and office automation management. One of them is a word processing electronic approach that allows us to create and revise letters, reports, and documents in a fraction of the time it would take to type manually. Many offices generate regular letters such as payment of the balance, invites, and so on. Furthermore, local business organizations utilize computers to generate, preserve and dispatch invoices to certain locations. The benefits of employing computers in this area are undeniably significant in a company organization.

In Banking and Financial

A company's operational budget manages data from savings accounts, fixed deposits, loans, investments, profitability analysis, and so on. Standard and recurring measures are used. As a result, financial institutions are the first to see the benefits of computers in saving time. Computers have made it easier for people to do baking or other financial tasks by themselves.

Employee wages will be deposited into the account when employee identification numbers are entered. When purchasing, the money sent into the account will be paid at supermarkets, motels, or petrol stations. A money transfer facility, also known as electronic money transfer, is a very effective and safe means for financial operations. Individuals can use the ETC capability to issue, transfer, and incorporate cash or checks to their existing balance at any moment. The fundamental purpose of employing computers in financial institutions is to help customers organize their affairs and provide better and more efficient services, to prevent fraud in financial transactions, and remove cash transactions that involve the community to achieve a cashless society.
