The correct answer is: B. Nerve center
The control unit is the part of a computer that is responsible for carrying out the instructions of a computer program. It is often called the “nerve center” of the computer because it controls all of the other parts of the computer.
The control unit receives instructions from the program memory and decodes them into a series of electrical signals. These signals are then sent to the appropriate parts of the computer, such as the arithmetic and logic unit (ALU) and the memory unit. The control unit also monitors the status of the computer and makes sure that all of the instructions are executed correctly.
The control unit is a very important part of the computer because it is responsible for carrying out the instructions of the program. Without the control unit, the computer would not be able to do anything.
The other options are incorrect because:
- The clock is a device that generates a regular stream of pulses that are used to synchronize the activities of the computer.
- ICs are integrated circuits that are used to build the various components of the computer.
- None of the above is a correct answer.
