C. A control unit and an arithmetic logic unit
D. An arithmetic logic unit and a card reader

Answer 1

c. A control unit and an arithmetic logic unit

Answer 2

Answer :-

Option C.

A control unit and an arithmetic logic unit.

A CPU contains a control unit (CU) and an arithmetic logic unit (ALU) and memory unit (MU).

Additional information :-

★ About CPU :-

• CPU stands for Central Processing Unit.

• CPU is also referred to as brain of the computer.

• The job of CPU is to process the instructions and give the required output.

The CPU is made up of 3 important parts :-

• Arithmetic Logic Unit (ALU) : It is a part of CPU which performs all Arithmetic operations like addition, Multiplication etc.

• Control Unit (CU) : It controls input and output devices and looks after the operation of the processor.

• Memory Unit (MU) : It helps in the storage of data primarily or temporarily. In simple terms, it is incharge of the storage.

Analytical Engine is a general purpose computer and Card Readers are devices which help to read the data on a Compact Flash or a MultiMediaCard.

As mentioned above CPU is made up of ALU , CU and MU.

Therefore the answer is

Option C.

A control unit and an arithmetic logic unit
