COMPUTER GENERATIONS

My ICT Lesson

1st Generation - Vacuum Tubes

In 1940 - 1956, computers used vacuum tubes.

Because computer used vacuum tibes, the computers were enormous.

It uses lot of electricity and gives out lot of heat and this cause breakdown.

These computer was limited to solve one problem at the time.

2nd Generation - Transistors

In 1956 - 1963, computer replaced vacuum tubes by transistors.

They were a big improvement over a vacuum tube.

The computers became more smaller, faster, cheaper and less heavy on electricity use.

3rd Generation - Integrated Circuits

In this time transistors being smaller and put on silicon chip.

This led computers a massive increase on speed.

These were the first computers which alows user to use keyboard and monitors.

This computer can run several applications at once using a central program.

4th Generation - Microprocessors

This revolution can be summarize in one word : INTEL.
The chip - maker developed the Intel 4004 chip in 1971 which positioned all computer components (CPU, memory, input/output controls) onto a single chip.
The machine that filled the room in the1940s now can fit into our palm of a hand.
In 1981 the first ever computer specifically designed for home use and 1984 the MacIntosh introduced by Apple.

5th Generation - Artificial Intelligence

Computer devices with artificial intelligence are still in development, but some of these technologies are beginning to emerge and be used such as voice recognition.
Leaning to the future, computers will be radically transformed again by quantum computation, molecular and nano technology.
The essence of fifth generation will be using these technologies to ultimately create machines which can process and respond to natural language, and have capability to learn and organize themselves.
