Computer Hardware Fundamentals

What are the main hardware components of a computer?

• Graphics card, sound card, cooling system

• Network cable, printer, monitor

• CPU, motherboard, RAM, storage devices, power supply, input/output devices.

• Webcam, external hard drive, keyboard

What is the primary function of a CPU?

• To store data permanently.

• To provide power to the computer.

• To manage network connections.

• To execute instructions from computer programs.

How does the clock speed of a processor affect performance?

• Higher clock speed typically improves processor performance, but other factors also play a significant role.

• Clock speed is the only factor that determines performance.

• Lower clock speed always results in better performance.

• Higher clock speed has no effect on performance.

What is the difference between RAM and ROM?

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

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

• RAM and ROM are both volatile and used for the same purpose.

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

What role does the motherboard play in a computer?

• The motherboard stores all the data and files of a computer.

• The motherboard acts as a cooling system for the CPU.

• The motherboard is responsible for powering the computer.

• The motherboard connects and allows communication between all components of a computer.

What are the different types of RAM available?

• Cache Memory

• Flash RAM

• DRAM, SRAM, SDRAM, DDR SDRAM, DDR2, DDR3, DDR4, DDR5

• EEPROM

How does a graphics card enhance computer performance?

• A graphics card is primarily used for audio processing.

• A graphics card only increases the computer's storage capacity.

• A graphics card has no impact on overall system performance.

• A graphics card improves performance by handling graphics processing, freeing the CPU for other tasks.

What is the purpose of a power supply unit in a computer?

• The purpose of a power supply unit in a computer is to convert and supply electrical power to the computer's components.

• To manage the computer's software applications.

• To store data permanently in the computer.

• To cool down the computer's components.

What are the key features to consider when choosing a CPU?

• Storage capacity

• GPU performance

• Key features to consider when choosing a CPU include core count, clock speed, cache size, TDP, and compatibility.

• RAM size

How does the architecture of a processor impact its efficiency?

• Processor architecture has no effect on efficiency.

• Efficiency is solely determined by the operating system.

• Processor architecture only affects physical size, not performance.

• Processor architecture impacts efficiency through instruction set design, pipeline optimization, cache management, and core utilization.
