Computer Architecture: Hardware Components Explained

What is the primary function of the Central Processing Unit (CPU) in a computer?

• Storing data permanently.

• Providing short-term memory for active tasks.

• Executing instructions and performing calculations.

• Connecting all other components and peripherals.

Which characteristic best describes Random-Access Memory (RAM)?

• It stores data permanently, even when the computer is off.

• It is a long-term storage device like a hard drive.

• It is volatile memory that temporarily holds data for quick access.

• It is primarily responsible for managing external devices.

What is a key difference between Hard Disk Drives (HDDs) and Solid State Drives (SSDs)?

• HDDs use flash memory, while SSDs use spinning magnetic disks.

• SSDs are generally slower and offer larger capacities at a lower cost.

• HDDs are typically faster and more expensive than SSDs.

• SSDs provide much faster data access speeds compared to HDDs.

What is the primary function of a Graphics Processing Unit (GPU)?

• To convert alternating current (AC) to direct current (DC) for computer components.

• To manage power distribution and communication between all computer components.

• To accelerate graphics rendering and process large amounts of data simultaneously for visual tasks.

• To maintain optimal operating temperatures and prevent overheating of critical components.

What is the main role of a Power Supply Unit (PSU) in a computer system?

• To process general computing tasks and manage overall system operations.

• To provide electrical power to all other computer parts by converting AC to DC.

• To render images, videos, and animations for display on a monitor.

• To allow users to provide data and commands to the computer.
