First generation: (Vacuum Tubes)
•used vacuum tubes for circuitry
•used magnetic drums for memory,
•often enormous
•They were very expensive
•generated a lot of heat
Common computer in this generation are:
•(Mark).
•(Anyak).
•(Edvak).
•(Insyak).
•(Yonivak).
•(IBM)

Third Generation: Integrated Circuits
•Development of the integrated circuit (I.C).
• Transistors were miniaturized and placed on
silicon chips, called semiconductors.

Fourth Generation: Present Microprocessors
The microprocessor brought the fourth generation of
computers, as thousands of integrated circuits were built
onto a single silicon chip. What in the first generation filled an
entire room could now fit in the palm of the hand. The Intel
4004 chip, developed in 1971, located all the components of
the computer - from the central processing unit and memory
to input/output controls - on a single chip.
As these small computers became more powerful, they could
be linked together to form networks, which eventually led to
the development of the Internet. Also, fourth generation
computers witnessed the development of GUIs, the mouse
and handheld devices.
