Exploring Computer Hardware Functions

What is the primary function of a CPU?

• To manage network connections.

• To provide power to the computer.

• To execute instructions from computer programs.

• To store data permanently.

How does the CPU execute instructions?

• The CPU executes instructions by only fetching data from memory.

• The CPU executes instructions by directly writing results to storage without processing.

• The CPU executes instructions by fetching, decoding, executing, and writing back results.

• The CPU executes instructions by decoding them into binary format only.

What are the main components of a CPU?

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

• Input/Output Interface (IOI)

• Cache Memory (CM)

• Memory Unit (MU)

What role does the ALU play in a CPU?

• The ALU performs arithmetic and logical operations in a CPU.

• The ALU manages input and output devices.

• The ALU controls the CPU's clock speed.

• The ALU stores data in memory.

What is the difference between RAM and HDD?

• RAM is non-volatile and slower than HDD.

• RAM is volatile and fast, while HDD is non-volatile and slower.

• HDD is volatile and faster than RAM.

• RAM and HDD serve the same purpose in a computer.

How does RAM affect computer performance?

• RAM affects computer performance by enabling faster data access and multitasking capabilities.

• RAM increases the physical size of the computer

• RAM is solely responsible for graphics performance

• More RAM always means a faster CPU

What is the purpose of cache memory in a CPU?

• To store all data permanently.

• To increase the CPU's power consumption.

• The purpose of cache memory in a CPU is to speed up data access by storing frequently used data and instructions.

• To replace the main memory entirely.

What is the function of the control unit in a CPU?

• The control unit handles all arithmetic calculations in the CPU.

• The control unit generates power for the CPU.

• The control unit directs the operation of the CPU by managing instruction execution and coordinating data flow.

• The control unit stores data temporarily for quick access.

How does an HDD store data?

• An HDD stores data in solid-state memory chips.

• An HDD stores data magnetically on spinning disks using read/write heads.

• An HDD stores data on paper tapes and ink.

• An HDD stores data using optical discs and lasers.

What are the advantages of SSD over HDD?

• SSDs are heavier and more fragile than HDDs.

• SSDs are faster, more durable, consume less power, and operate silently compared to HDDs.

• SSDs are cheaper and have larger storage capacities than HDDs.

• SSDs require more power and generate more heat than HDDs.
