Understanding Computer Hardware

What are the main types of computer memory?

• Virtual memory (Swap space)

• Cache memory (CPU)

• Primary memory (RAM) and Secondary memory (HDD, SSD)

• Optical memory (CD, DVD)

What does RAM stand for and what is its purpose?

• Random Access Memory

• Rapid Access Memory

• Read Access Memory

• Random Access Module

What does ROM stand for and how does it differ from RAM?

• ROM stands for Read-Only Memory and differs from RAM in that ROM is non-volatile and retains data without power, while RAM is volatile and loses data when power is off.

• RAM stands for Read-Access Memory and is non-volatile like ROM.

• ROM stands for Random Access Memory and is volatile like RAM.

• ROM is a type of RAM that can be written to multiple times.

Name a type of non-volatile memory.

• RAM

• Hard disk

• Flash memory

• Optical disc

What is the primary function of the CPU?

• To provide power to the computer

• To store data permanently

• To manage network connections

• The primary function of the CPU is to execute instructions and process data.

What are the main components of a CPU?

• Arithmetic Logic Unit (ALU), Control Unit (CU), Registers

• Graphics Processing Unit (GPU)

• Input/Output Controller (IOC)

• Memory Management Unit (MMU)

How does RAM affect a computer's performance?

• More RAM always means a faster CPU.

• RAM has no impact on application loading times.

• RAM only affects the graphics quality of games.

• RAM affects a computer's performance by enabling faster data access and improving multitasking capabilities.

What is the difference between primary and secondary storage?

• Primary storage is used for long-term data retention, while secondary storage is for temporary data access.

• Primary storage is volatile and fast, while secondary storage is non-volatile and slower.

• Primary storage is larger in capacity than secondary storage, which is smaller and faster.

• Primary storage is non-volatile and slower, while secondary storage is volatile and fast.

List three common storage devices.

• CD-ROM

• Floppy Disk

• Hard Drive, Solid-State Drive, USB Flash Drive

• External Battery

What is the purpose of input devices?

• To connect the computer to the internet.

• The purpose of input devices is to allow users to input data and commands into a computer.

• To store data permanently.

• To display data on the screen.
