Free Bachelor of Computer Engineering Computer Architecture Questions and Answers

Question 1

Why is computer architecture important?

Accepted Answer

set of principles and methods that specify the functioning, organisation, and implementation of computer systems

Answer

Computer architecture is a fundamental concept that defines the operational structure of a computer system. It encompasses the set of principles and methods that specify how a computer system functions, its organizational structure, and how it is implemented. This includes aspects like the instruction set, memory organization, and input/output mechanisms, all crucial for the system's overall performance and functionality.

Question 2

What kind of computer architecture is the following?

Accepted Answer

All of the above

Answer

Computer architecture is a broad field that encompasses several distinct but related architectural types. Von-Neumann architecture and Harvard architecture describe different ways instructions and data are handled in memory. Microarchitecture refers to the specific implementation details of an instruction set architecture. Therefore, all these are valid classifications within the realm of computer architecture.

Question 3

Which of the following describes the architecture used today in computers?

Accepted Answer

Von-Neumann Architecture

Answer

The Von-Neumann architecture is the most widely adopted design for modern general-purpose computers. It is characterized by a single address space for both instructions and data, allowing the CPU to fetch both from the same memory unit. This unified memory model simplifies the design and is fundamental to how most personal computers and servers operate today.

Question 4

Which of the following groups would you classify as computer architecture?

Accepted Answer

Microarchitecture

Answer

Among the given options, microarchitecture is a direct classification within computer architecture. While Instruction Set Architecture (ISA) defines the programmer's view of the processor, microarchitecture describes the specific internal implementation of that ISA. It details the components like ALUs, registers, caches, and their interconnections, which together execute the instructions defined by the ISA.

Question 5

Which architectural design is the most energy-efficient?

Accepted Answer

RISC

Answer

RISC (Reduced Instruction Set Computer) architecture is generally considered more energy-efficient than CISC (Complex Instruction Set Computer) architecture. RISC processors use a smaller, simpler set of instructions that execute quickly and with fewer clock cycles. This simplicity often translates to less power consumption and heat generation, making them ideal for mobile devices and embedded systems where energy efficiency is critical.
