Explanation:
Detailed explanation-1: -The ISA is longer (by about two inches), and thus the I/O cards that connect via ISA tend to be bulkier as well. Their differences do not stop there. PCI is a significantly faster (in theory) bus. PCI has double (or in rare instances, quadruple) the bit-width, resulting in faster data transfer.
Detailed explanation-2: -History. The concept for the ISA bus was developed in 1981 by an IBM design team led by inventor and computer engineer Mark Dean. The bus was designed to support the Intel 8088 microprocessor for IBM’s first-generation PCs.
