MAH-CET 2026 — Computer PYQ

The correct option is (a) Memory.

Detailed Explanation

• Memory: The primary function of a computer's memory unit (such as RAM and Cache) is to act as a workspace. It holds the active data, intermediate variables, and specific software instructions that the CPU needs to access quickly during execution. It also holds the final processed output results before they are sent to an external destination.

• Input: Input units (like keyboards or mice) are used to enter raw data into the computer system; they do not store data during active processing.

• Output: Output units (like monitors or printers) display or present the finalized results to the user, rather than storing active data instructions during computation.

• Architecture: Computer architecture is the design framework or conceptual structure of a computer system, not a physical hardware storage entity.

We can model the data flow within a basic Von Neumann architecture model. Let the total operational data state $S$ required during a computational processing cycle be a union of input data $D_{\text{in}}$, software instructions $I$, and output results $R_{\text{out}}$:

$$S=D_{\text{in}}\cup I\cup R_{\text{out}}$$

The mapping of this state $S$ into the storage space of the computer system memory $M$ during an active processing phase can be represented as:

$$S\subseteq M$$

This highlights that the entire set of elements essential for execution resides inside the Memory component.
