Answer 2

Answer:

The First Generation

Computers in this generation were so enormous that they took up whole rooms.

They used vacuum tubes for circuitry and magnetic drums for memory.

First Generation Computers

They were very expensive to operate and in addition to using a great deal of electricity, they generated a lot of heat, which was often the cause of malfunctions.

The Second Generation

Transistors replaced vacuum tubes and ushered in this generation of computers. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their predecessors.

Second Generation Computers

Although the transistor was a vast improvement over the vacuum tube, these computers still relied on punched cards for input, printouts for output and generated a great deal of heat.

The Third Generation

Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.

The Fourth Generation

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

GUIs, the mouse and handheld devices were also developed in this generation.
