Question

The ______ register is read by the host to get input.

a) Flow in
b) Flow out
c) Data in
d) Data out

Answer 1

The register read by the host to get input is the 'Data in' register, a small storage location within the CPU for quickly accessing incoming data.

Step-by-step explanation:

The register read by the host to get input is known as the Data in register. Registers are small storage locations within the CPU used to hold data that can be accessed quickly. In the context of input/output operations, the Data in register is where the CPU or host system can read incoming data. This is distinct from the Data out register, which is used to hold data that is being sent from the CPU to another device.
