Question

Which of the following does ALU and control units together form ?(a) Central processing unit
(b) Control processing unit(c) Memory
(d) Input/Output unit

Answer 1

ALU and Control units(Cu) together form-:
a) Central processing unit

Answer 2

ALU and control units together form the (a) Central processing unit.

• The control unit tells the ALU what operation is to be performed on the given data and the ALU stores the result and provides the output.
• The control unit moves the data between the ALU and memory.
• The ALU has direct input and output access to the processor controller, main memory and input/output devices.
• Inputs and outputs flow along an electronic path that is called a bus.
• ALU stands for Arithmetic Logic Unit and is a major component of the Central processing unit.
• The control unit is the component of the processor that directs and coordinates most of the operations in the computer.
