Computer Architecture Overview

What is the purpose of a memory hierarchy in computer architecture?

• Managing input/output operations

• Increasing the size of virtual memory

• Minimizing CPU clock speed

• Enhancing data access speed by using different types of memory

Which storage technology uses magnetic fields to store data on rotating disks?

• Flash memory

• Solid-state drive (SSD)

• Hard disk drive (HDD)

• Optical disc

Which component is responsible for temporarily storing data that the CPU needs during operations?

• Hard disk

• RAM (Random Access Memory)

• Cache memory

• ROM (Read-Only Memory)

What is the purpose of the control unit in the CPU?

• Managing memory storage

• Performing arithmetic calculations

What does the term "pipeline hazard" refer to in computer architecture?

• A security vulnerability in software

• A malfunction in the CPU cooling system

• A delay in instruction execution due to resource conflicts

• A network connectivity issue

What is the role of the input/output (I/O) subsystem in computer architecture?

• Executing arithmetic operations

• Facilitating communication between the CPU and external devices

• Controlling power supply
