The ALU and control unit of most of the microcomputers are combined and manufactured on a single silicon chip. What is it called?

The correct answer is A. Monochip.

A monochip is a

single integrated circuit that contains all the components of a microcomputer, including the ALU, control unit, and registers. Monochips are typically used in embedded systems, where space and power are limited.

A microprocessor is a single integrated circuit that contains the central processing unit (CPU) of a computer. The CPU is responsible for carrying out the instructions of a computer program.

An

ALU is an arithmetic logic unit, which is a part of the CPU that performs arithmetic and logical operations.

A control unit is a part of the CPU that controls the flow of instructions in a computer program.

E is not the correct answer because it is not a valid option.
