IGDTUW 2025 — Computer PYQ

The correct answer is (b) set of principles and methods that specify the functioning, organisation, and implementation of computer systems.

Explanation

Computer architecture is defined as the science and art of selecting and interconnecting hardware components to create a computer that meets functional, performance, and cost goals. It establishes the foundational principles and methodologies that dictate how a computer system functions, how it is organized, and how it is implemented.

Conceptual Mathematical Model

We can view computer architecture as a structural mapping between the conceptual principles and the physical implementation. If $P$ represents the principles and $I$ represents the implementation methods, then the total architecture $A$ can be represented as:

$$A=f(P,M)$$

Where $M$ is the organization method and $f$ is the functional specification. The goal of architecture is to optimize the system output ($S_{out}$) relative to the input requirements ($R_{in}$):

$$Optimization=\frac{S_{out}}{R_{in}}$$

This formalization shows that architecture is not merely a set of categories or functions, but a disciplined application of principles and methods to achieve a desired operational outcome.
