The IO device that can be interfaced with 8089 is
A. 16-bit IO
B. 8-bit IO
C. 64-bit IO
D. 16-bit and 8-bit IO
Answer:A
The IO device that can be interfaced with 8089 is
A. 16-bit IO B. 8-bit IO C. 64-bit IO D. 16-bit and 8-bit IO
Explanation: The 8089 handled IO devices need not have the same data bus width as that of 8089. This enables even 8-bit IO devices to be interfaced easily with 8089.
