The 4 genertion of computer

The first generations.

They were very expensive to operate and in addition to using a great deal of electricity.

The second generations

The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.

The third generation

The development of the integrated circuit was the hallmark of the third generation of computers

The forth generation

As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet.
