1. Hardware (Computer Architecture)

Parallel processing operates on certain principles and has associated drawbacks. Which of the following best describes these principles?

• Executing multiple processes simultaneously to increase computational speed.

• Running a single process on multiple processors to reduce power consumption.

• Using a single processor to execute tasks sequentially for better accuracy.

• Executing tasks in a linear fashion to ensure data integrity.

What is cache memory in a Central Processing Unit (CPU) and what are its advantages?

• A type of volatile memory that stores frequently accessed data for quick access.

• A permanent storage solution for all data in a computer.

• A type of memory used only for graphics processing.

• A backup storage for all system files.

What is the fetch-execute cycle and how does it show data being read from RAM into registers?

• It is a process where the CPU fetches an instruction from memory, decodes it, and then executes it, involving the transfer of data from RAM to registers.

• It is a cycle where data is written from registers back to RAM.

• It is a process where the CPU only executes instructions without fetching them.

• It is a cycle that involves only the storage of data in RAM without any execution.

Which of the following best describes the role of a CPU in a computer system?

• The CPU is the main processing unit that executes instructions and processes data.

• The CPU is responsible for storing all data permanently.

• The CPU is used exclusively for rendering graphics.

• The CPU is a backup unit for data storage.

What is the primary function of an Arithmetic Logic Unit (ALU) within a CPU?

• To perform arithmetic and logical operations on data.

• To store data permanently.

• To manage the power supply of the computer.

• To handle network communications.

What is the significance of the clock speed in a CPU?

• It determines how many instructions per second the CPU can execute.

• It indicates the amount of data the CPU can store.

• It shows the number of cores in the CPU.

• It measures the power consumption of the CPU.

What role does the Control Unit (CU) play in a CPU's operation?

• The CU directs the operation of the processor and coordinates the activities of the CPU.

• The CU stores data permanently within the CPU.

• The CU is responsible for performing arithmetic operations.

• The CU manages the computer's network connections.

What is the impact of increasing the size of cache memory in a CPU?

• It can improve the CPU's performance by reducing the time needed to access frequently used data.

• It decreases the CPU's overall processing speed.

• It increases the CPU's power consumption significantly.

• It has no effect on the CPU's performance.

What is the function of the Program Counter (PC) in a CPU?

• The PC holds the address of the next instruction to be executed.

• The PC stores data permanently within the CPU.

• The PC performs arithmetic operations.

• The PC manages the computer's network connections.

What is the role of registers in a CPU?

• Registers provide a small amount of fast storage for immediate data processing.

• Registers are used to permanently store all data in the CPU.

• Registers manage the power supply of the computer.

• Registers handle network communications.
