Q1. What is the main function of the central processing unit (CPU) in computers?
A To process data Correct
B To display data
C To transmit data
D To store data
Explanation
The central processing unit is the main processing component of a computer. It fetches instructions, decodes them, performs arithmetic and logical operations, and controls the execution of programs. Displaying data is mainly the role of output devices such as a monitor. Transmitting data is handled by communication devices and network interfaces. Storing data is the work of memory and storage devices such as RAM, hard disks, and solid-state drives, though the CPU coordinates their use.
