Understanding Computer Hardware

What is the primary function of the CPU in a computer system?

• To manage network connections

• To provide power to the computer

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

• To store data permanently

Explain the difference between RAM and ROM.

• RAM is volatile and used for temporary storage; ROM is non-volatile and used for permanent storage.

• RAM is used for permanent storage; ROM is used for temporary storage.

• RAM is non-volatile and used for temporary storage; ROM is volatile and used for permanent storage.

• RAM and ROM are both volatile and serve the same purpose in a computer.

Identify three types of storage devices and their characteristics.

• Network Attached Storage (NAS): Fast, limited portability, complex setup.

• 1. Hard Disk Drive (HDD): Mechanical, large capacity, cost-effective. 2. Solid State Drive (SSD): Fast, durable, higher cost. 3. USB Flash Drive: Portable, convenient, limited capacity.

• Tape Drive: Portable, high capacity, expensive.

• Optical Disc: Slow, high durability, low capacity.

How does a motherboard connect different hardware components?

• A motherboard connects hardware components via sockets, slots, and ports.

• A motherboard connects components via USB cables.

• A motherboard connects components using wireless signals.

• A motherboard connects hardware through software drivers.

What role does the power supply unit (PSU) play in a computer?

• The PSU cools the computer's components.

• The PSU stores data for the computer.

• The PSU supplies power to the computer's components.

• The PSU manages the computer's software.

Describe the function of a graphics processing unit (GPU).

• The function of a GPU is to accelerate graphics rendering and perform parallel processing for complex calculations.

• A GPU is primarily used for storing large amounts of data.

• The main function of a GPU is to manage system memory.

• A GPU is designed to enhance audio processing capabilities.

What are the advantages of using SSDs over HDDs?

• SSDs offer faster speeds, greater durability, lower power consumption, and silent operation compared to HDDs.

• SSDs are more prone to mechanical failure than HDDs.

• SSDs have a higher cost per gigabyte than HDDs.

• SSDs require more power to operate than HDDs.

How can overheating affect computer hardware performance?

• Overheating enhances system stability and reliability.

• Overheating improves performance by increasing processing speed.

• Overheating has no effect on hardware performance.

• Overheating negatively impacts performance by causing thermal throttling, hardware damage, and system instability.

Explain how input and output devices interact with the CPU.

• Input devices send data to the CPU for processing, and output devices receive processed data from the CPU.

• Input devices only receive data from the CPU.

• Output devices send data to the CPU for processing.

• Input and output devices do not interact with the CPU.

What factors should be considered when selecting hardware for a gaming PC?

• Mouse sensitivity

• CPU, GPU, RAM, Storage, Motherboard, Power Supply, Cooling

• Keyboard type

• Monitor size
