Second Generation Computers (1956- 1963)

In the second generation computers, transistors were used as processors instead of vacuum tubes. Transistors were far superior to vacuum tubes allowing computers to become smaller,faster and cheaper. These computers were smaller in size and were in use between 1956 and 1963. Both first and second generation computers used punched cards as input and printouts as output. IBM 704 and IBM  1401 are examples of the second computers.

Some features of the features of the second generations computers are list below

• They were more energy-efficient and reliable than the first generation computers.
• Their operating speed was comparatively higher than the first generation computer.
• High level programming languages like COBOL and BASIC were developed in this generation.

First Generation Computers (1940-1956)

The first generation computers were in use between 1940 and 1956. Scientists used vacuum tubes as processors in them. They were so big that they occupied an entire room.
 some features of the first generation are given below-

• Their speed was quite low and power (electricity) consumption was very high.
• Inputs in such computers were in the form of punched cards and paper tapes.
• Their programming capacity was very low.
• They could not store much data.
• They were huge in size and very expensive.

Some more information

The computers we see today have been developed part by part by many scientists In fact, the history of computer comprises a gradual development from simple abacus to the electronic computers we use today.

In 1837, Charles Babbage, a British scientist, made first computer. It was a mechanical computer which could do very large calculations. Since then,many people have contributed to the improvement of computers.

The history of computers is often referred to as different generations of computers. With every generations of computers,there was a major development in technology.
As a result, computers became smaller,cheaper, more powerful and more efficient.
 
So far, we know about five generations of computers.

What do you mean by generation of computer

The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. There are five generations of computer. Each generation is characterized by major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, and more powerful and more efficient and reliable devices.
