Match the List-I with List-II.

List-I (Device)		List-II (Function)
A.	CPU	I.	stores data temporarily
B.	Monitor	II.	stores data permanently
C.	RAM	III.	Processes Instructions
D.	Hard disk	IV.	Displays visual output

Choose the correct answer from the options given below

The correct option is (A)-(III), (B)-(IV), (C)-(I), (D)-(II).

Let us understand the function of each computer device listed in List-I to see why they match with the functions in List-II:

A. CPU matches with III (Processes Instructions):
The CPU (Central Processing Unit) is the primary component of a computer that acts as its "brain." It is responsible for executing program instructions by performing basic arithmetic, logical, control, and input/output operations.

B. Monitor matches with IV (Displays visual output):
A monitor is an output device that presents information in pictorial form. It receives video signals from the computer's graphics hardware and displays them as visual output (images, text, and videos) on the screen for the user.

C. RAM matches with I (stores data temporarily):
RAM (Random Access Memory) is a type of volatile computer memory. It is used to hold data and instructions that the CPU needs in real-time while performing tasks. Because RAM is volatile, it only stores data temporarily and loses all its contents when the computer is powered down.

D. Hard disk matches with II (stores data permanently):
A hard disk is a non-volatile secondary storage device. It is used to store data, software, files, and the operating system permanently. Since it is non-volatile, the stored data remains safe and intact even when the computer is turned off.
