Key Points

Computer Components	Description
HDD	HDD is an electro-mechanical storage device, which is an abbreviation of Hard Disk Drive. It uses magnetic storage for storing and retrieving digital data. It is a non-volatile storage device. It is an External Memory.
RAM	RAM is a volatile memory. It means it does not store data or instructions permanently. CPU utilizes this data to perform the required tasks. As soon as the computer is shut down the RAM loses all the data.
ROM	ROM is a non-volatile memory. It means it does not lose its data or programs that are written on it at the time of manufacture. It is a read-only memory that can only read stored information, data, or programs, but we cannot write or modify anything. Hence it is also called as non-writable memory
CRT	CRT stands for Cathode Ray Tube. CRT is a technology used in traditional computer monitors and televisions. It is a type of Visual Display Unit in computers. The CRT in a computer display is similar to the "picture tube" in a television receiver.

Therefore we conclude that the correct matching code is (A) - (III), (B) - (II), (C) - (IV), (D) - (I).
