COMPUTER FUNDAMENTALS

Detailed explanation-1: -Fourth-generation computers were introduced in 1972, following the third-generation computer that largely used microprocessors. These computers used VLSI technologies, and Very Large Scale Integrated (VLSI) circuits.

Detailed explanation-2: -fourth generation computers integrated circuitry had advanced to very large-scale integration (VLSI). This design and manufacturing technology greatly increased the circuit density of microprocessor, memory, and support chips-i.e., those that serve to interface microprocessors with input-output devices.

Detailed explanation-3: -VLSI technology, or Very Large Scale Integrated (VLSI) circuits, was employed in these computers. As a result, they were dubbed microprocessors. A microprocessor is made up of thousands of integrated circuits that are assembled on a single chip known as a silicon chip.

Detailed explanation-4: -In fourth generation computers the semiconductor memory is replaced by magnetic core memory resulting in fast random access to memory. Several operating systems like MS-DOS and MS windows developed during this time.
