Explanation:
Detailed explanation-1: -Stands for “Industry Standard Architecture.” ISA is a type of bus used in PCs for adding expansion cards. For example, an ISA slot may be used to add a video card, a network card, or an extra serial port. The original 8-bit version of PCI uses a 62 pin connection and supports clock speeds of 8 and 33 MHz.
Detailed explanation-2: -ISA bus architecture There are 24 address lines and ‘16 data lines in it. It operates at 8 MHz and 2 to 8 clock cycles are needed to transfer data. The data transfer rate of the system is less when 8-bit ISA bus is used with 32 bit processor having 32 bit address and data bus.
