Question

The host controller is :

a) controller built at the end of each disk
b) controller at the computer end of the bus
c) both a and b
d) neither a nor b

Answer 1

The host controller manages the data transfer between the computer's CPU and connected disk drives, and it is located at the computer end of the bus, rather than on the disk itself.

Step-by-step explanation:

The host controller is a term used in computing to describe a component that manages the interface between the computer system and the peripherals connected to it. In the context of the question, the correct answer is b) controller at the computer end of the bus.

This means the host controller is responsible for managing the data transfer between the computer's central processing unit (CPU) and the disk drives connected to it through a bus such as SATA (Serial ATA) or SCSI (Small Computer System Interface).

Answer 2

The host controller is the device responsible for managing the flow of data between a computer and a peripheral device (Option B).

Step-by-step explanation:

The host controller can be defined as the device or component that is responsible for managing and controlling the flow of data between the computer and a peripheral device, such as a disk. The host controller is usually integrated into the motherboard or connected externally via a USB or other interface.

The host controller is a component that manages the communication between the computer system and its peripheral devices. In the context of data storage and retrieval, specifically when dealing with buses and disk drive

In this case, the correct answer would be an option B) the controller at the computer end of the bus.
