Answer

The difference between the third generation computers and the fourth generation computers are as follows:

Third Generation

• They used integrated circuit (I.C) and large scale integration (LSI).
• They were smaller in size and called as mini computer.
• The operating speed was measured in nano seconds.
• Main memory was increased in the form of PROM and DRAM.
• Magnetic disks were used for secondary storage.
• They could understand large number of high level languages.

Fourth Generation:

• They used very large scale integration (VLSI) and microprocessor.
• They were small in size and called as micro computer.
• They could perform millions of calculations per second.
• Main memory was increased in the form of EPROM and SRAM.
• They have a large memory and high functional speed.
• Multiprocessing and multiprogramming OS (operating system) are used

Answer

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.

Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.

Fourth Generation (1971-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.

In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.

As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.
