The Industry Standard Architecture bus or also known as the "AT bus" was developed for the 16-bit processor. The ISA slot has begun to approach its final days as computer developers are beginning to avoid the use of ISA slots. This is not due to any grudges or ill feelings, but mainly due to performance issues. The ISA slot is one of the slowest slots available, which means it communicates with the CPU at extraordinary slow rate. It is distinguishable by its long double connector, which is a small bus connector placed behind the original 8-bit connector.

Note: The ISA is one of the few slots that is backward compatible.
