A Level Computer Science - Chapter 3 Hardware

What is the functionality of computer system hardware?

• To water plants and walk the dog

• To process data, perform calculations, and execute instructions.

• To cook food and clean the house

• To play music and watch movies

What are the main memory components of a computer system?

• Keyboard and mouse

• Hard drive and SSD

• CPU and GPU

• RAM and ROM

Explain the purpose of secondary storage devices in a computer system.

• To store data and programs for long-term use, even when the computer is turned off.

• To connect the computer to the internet

• To cool down the computer system

• To provide power to the computer system

How does computer system hardware functionality differ from embedded systems?

• Embedded systems are more expensive than computer system hardware

• Embedded systems are designed for specific tasks and are often part of a larger system, while computer system hardware is more general-purpose and can run a variety of software applications.

• Embedded systems are not part of a larger system, unlike computer system hardware

• Computer system hardware is designed for specific tasks while embedded systems are general-purpose

What are the different types of memory components in a computer system?

• CPU, GPU, PSU

• Keyboard, mouse, monitor

• RAM, ROM, cache memory

• Hard drive, SSD, CD drive

Discuss the importance of secondary storage devices in modern computer systems.

• They are only used for storing small amounts of data

• They are not necessary in modern computer systems

• They provide non-volatile storage for data and programs, allowing for long-term storage and retrieval of information.

• They are only used for temporary storage of data and programs

Explain the role of output devices in a computer system.

• Output devices control the speed of the computer system.

• Output devices present the processed information to the user.

• Output devices input information into the computer system.

• Output devices store data in the computer system.

What are the advantages of using embedded systems in electronic devices?

• No change in performance, same size, cost-neutral, and no impact on reliability.

• Decreased performance, increased size, expensive, and decreased reliability.

• Improved performance, reduced size, cost-effectiveness, and increased reliability.

• No impact on performance, increased size, cost-ineffective, and decreased reliability.

How does RAM differ from ROM in terms of memory components?

• Fast vs. slow

• Hard vs. soft

• Blue vs. red

• Volatile vs. non-volatile

Compare and contrast different types of secondary storage devices.

• Compare the color of the devices

• Consider the brand of the devices

• Contrast the weight of the devices

• Consider factors such as storage capacity, access speed, portability, durability, and cost.
