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.
