From the History of Computers.

The educated man of 200 years ago did not need to know anything about science. The educated man of 25-30 years ago did not need to know anything about computers. But the educated man of today needs to have some significant knowledge of science and a little significant knowledge about computers.

The computer is no doubt the most amazing achievement of mankind. It is a data storage system created by man. A human tells the machine what to do, when to do it and how it should be done.

The word computer comes from a Latin word which means to count.

Nearly one hundred fifty years ago there were no such things as computers. Knotted ropes, marks in clay, the abacus were all the methods of keeping track of numbers.

In 1833 an English inventor and mathematician Charles Babbage, professor of Cambridge University designed the first computer. The mathematical programme for his machine had been composed by Augusta Ada Byron, Lord Byrons

Computers in our life

 

The first digital computer was completed in 1944. Since that time, there have been many changes. Now computers are smaller, cheaper, and more common. There are few people who have not worked with a computer, either directly or indirectly. Banks, businesses, hospitals, universities, and airlines all use computers. Libraries also use computers to check out books.

Up until now, the computer has been used most often in business, where it was first used for accounting. This is still its most common use. It can list and remember the number of products that the business buys and sells. It can also calculate the average cost of the products in the store. It can tell the businessman when they need to buy more. Management uses it to prepare business reports and to make decisions. It can predict the future of the business so the management can use the information when it has to make important decisions.

Many banks use computers to process customers checks and to keep records of their money. Outside many banks, there are automatic tellers, which are computers. People use them when the bank is closed. They can deposit money, they can get cash, and they can transfer money from a savings account to a checking account and vice versa.

Computers that are used in factories to control the assembly line put together cars, airplanes, and other machines. They do jobs that are difficult, dangerous, or boring for people to do. A computer is also used to check quality in the factory because it can test products to see if they are satisfactory. Chemical companies often use computers to analyze their processes and check their products.

In the travel industry, computers are widely used to make reservations for airlines and hotels. Passengers do not have to wait days or weeks to see if there are seats on the airplanes because the computer can give them the information immediately.

Schools are beginning to use the computers more and more because it can teach many kinds of lessons. Pupils have the chance to learn at their own speed. Some pupils can work slowly, others can work quickly. The computer tells them if their answers are right or wrong. The computers can help pupils to review if they need to. One computer system that is used in education is PLATO. It teaches English!
