What is the function of the Arithmetic Logic Unit (ALU) in a CPU?

• It manages the execution of instructions.

• It stores data temporarily.

• It processes and manipulates arithmetic operations and logical comparisons.

• It synchronizes the clock speed of the processor.

What does the Program Counter (PC) do?

• It stores the address of the next instruction to be executed.

• It accumulates the results of arithmetic operations.

• It decodes and synchronizes instructions.

• It transfers data from the memory to the CPU.

Which register temporarily holds the data currently being processed by the central processor?

• Memory Address Register (MAR)

• Memory Data Register (MDR)

• Accumulator

• Current Instruction Register (CIR)

What is the role of the Current Instruction Register (CIR)?

• It holds the address of the data being accessed.

• It stores the results of arithmetic operations.

• It stores the address of the next instruction being executed and decoded.

• It synchronizes the clock speed of the processor.

The main purpose of the Control Bus within the computer architecture is (a)   .

• It carries data between the process
• It carries control and status signa
• It synchronizes the clock speed of
• It stores the address of the next i

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

• It determines the size of the cache.

• It controls the rate at which instructions are executed.

• It stores the results of arithmetic operations.

• It carries control and status signals between different components of a computer.

What is the primary function of cache in a CPU?

• It stores the address of the next instruction to be executed.

• It carries data between the processor and the memory.

• It provides extremely fast access to sections of a program and associated data.

• It synchronizes the clock speed of the processor.

Which architecture allows for steps of an instruction sequence to be executed in turn by a sequence of cores?

• Von Neumann Architecture

• Harvard Architecture

• Contemporary Architecture

• Pipelining

What distinguishes Reduced Instruction Set Computer (RISC) from Complex Instruction Set Computer (CISC)?

• RISC relies on a complicated and expensive integrated circuit.

• RISC provides no access to the instruction storage as data.

• RISC produces a simple, cheap integrated circuit with a basic range of machine instructions.

• RISC is a design that executes a few machine cycles.

What is the primary function of a GPU?

• To process and store data in memory chips

• To translate signals from the computer into a human-readable form

• To rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer

• To organize memory into fixed-sized units called pages
