What is the function of the Accumulator (ACC) in a computer?

• It carries the memory location address of the register.

• It performs arithmetic calculations and logical operations.

• It temporarily stores the results of operations performed by the ALU.

• It stores instructions and data that are accessed regularly.

Which bus carries the memory location address of the register the data is being carried to or from?

• Data Bus

• Address Bus

• Control Bus

• System Bus

What does the Arithmetic and Logic Unit (ALU) do?

• It stores instructions and data that are accessed regularly.

• It performs arithmetic calculations and logical operations on data.

• It carries control signals from the CU to synchronize access and use of data.

• It temporarily stores data to be read from or written to the computer’s memory.

What is the primary function of the Cache in a CPU?

• To carry data and instructions between the processor and memory.

• To store the memory address of the next instruction to load or data to use.

• To store instructions and data that are accessed regularly.

• To control the execution of instructions and coordinate execution.

What does Clock Speed control in a CPU?

• How often instructions are executed and data is fetched per second.

• The memory location address of the register.

• The process of fetching from memory and executing the instruction.

• The storage of the current instruction being executed and decoded.

What is Concurrent Processing?

• The process of fetching from memory and executing the instruction.

• More than one task happening ‘in progress’ at the same time.

• A modern computer architecture combining elements of both Von Neumann and Harvard architectures.

• A bi-directional bus carrying control signals from the CU to synchronize access and use of data.

What is the function of the Control Unit (CU) in a CPU?

• It stores the current instruction being executed and decoded.

• It carries data and instructions between the processor and memory.

• It controls and manages the execution of instructions.

• It stores the memory address of the next instruction to load or data to use.

What is the purpose of the Memory Address Register (MAR)?

• To temporarily store data to be read from or written to the computer’s memory.

• To store the memory address of the next instruction to load or data to use.

• To carry data and instructions between the processor and memory.

• To store instructions and data that are accessed regularly.

What is a core in the context of computer processors?

• A. A special memory cell that can be accessed quickly.

• B. A processing unit that handles instructions with its own fetch-execute-decode cycles.

• C. A special purpose register that stores the address of the next instruction to execute.

• D. A computer architecture where a single control unit manages program control.

What is parallel processing?

• A. The simultaneous decoding of several instructions.

• B. A special form of concurrency where tasks are processed simultaneously with multiple cores/processors.

• C. A special purpose register that stores the address of the next instruction to execute.

• D. A computer architecture where data and instructions are stored in a shared memory space.
