How is EISA bus different from ISA bus?
Extended Industry Standard Architecture (EISA) is a 32 bit modification to ISA bus. As computers became larger and had wider data buses, a new bus was required that would transfer 32-bit data. Clocking speed limited up to 8MHz. The most common application for EISA bus is a disk controller or as a video graphics adapter. These applications benefit from wider data bus width since the data transfer rate for these devices are high.
