Program Description Answer
CPU’s job is to get the information and to perform actions commanded by the instructors to produce resultant information.
Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
CPU (Central Processing Unit):
- CPU is called as the Heart of a Computer, because it stores and retrieves data.
- It is the component of the computer which is responsible for executing many commands.
- CPU contains two parts namely: Control unit and Arithmetic Logic Unit.
- It is mainly used to get the instructions as well as to perform the mathematical operations.
Explanation for incorrect options:
Memory is a storage location of data which can be accessed directly.
Hence, the option “A” is wrong.
When the data is stored using any external memory device whose contents are non-volatile in nature are termed as “Secondary storage”.
Hence, the option “C” is wrong.
When the data is collected from the user through any device is called as input device.
Hence, the option “D” is wrong.
