Q. The term that we use to describe physical components of the system

Explanation by: Mr. Dubey

Hardware refers to the physical components of a computer system such as the keyboard, monitor, CPU, RAM, hard drive, motherboard, etc.
Why other options are incorrect:
(B) Inout: This seems to be a typo; likely meant "Input", but even then, it's not a general term for physical components.
(C) Software: Refers to programs and applications — the non-physical part of the system.
(D) None of these: Incorrect because Hardware is the correct and valid term.
