fourth generation computer definition architecture
A computer built using Very Large Scale Integration
(VLSI) integrated circuits
, especially a microcomputer
based on a microprocesseor, or a parallel processor
containing two to thousands of CPUs.
VLSI made it routine to fabricate an entire CPU, main memory, or similar device with a single integrated circuit that can be mass produced at very low cost. This has resulted in new classes of machines such as personal computers
, and high performance parallel processors that contains thousands of CPUs.
