First generation of computers

The first generation of computers

First  computer of this world

The first generation of computers is said by some to have started in 1946 and ended in 1949. Others said that this generation was started in 1945 and ended in 1950. Some computer historians argue that the first generation actually started in 1959. The first 'computer' to use electronic valves  were  vacuum tubes.

Vaccum tube

These vaccum tubes were huge and could not work without airconditioned. The first generation computers began  because that was the year when people consciously set out to build stored program computers. This  period was  closed  with the introduction of transistors. These transistors took place of vaccum tubes. Each computer was hand designed, individually engineered and hand fabricated.

In 1946 there was no 'best' way of storing instructions and data in a computer memory.  First generation computers were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.The operating systems of the first generation computers were very slow.They were very large in size. They were difficult to program and use.And these First  computers were unreliable. The lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time.

FIRST GENERATION COMPUTER

The history of computer development is often in reference to the different generations of computing .These computers run with vacuum tubes.So this first generation computers  age was called ENIAC. ENIAC computers are examples of first-generation computing devices. That ENIAC was the World's first electronic calculator. These computers wre very costly because thousands of people work to run them and a vast area required to place them. Vaccum tubes needed a cool enviroment. For this purpose air conditioned were used. It used 18,000 vacuum tubes, took up 15,000 square feet of floor space and weighed in at a hefty 30 tons.
