GCSE Comp Sci - Unit 3 Computers

What is the Von Neumann architecture?

• A type of computer memory

• A processor connected to a memory unit via a set of buses

• A programming language

• A computer network topology

What does the Stored program concept refer to?

• The idea that programs are stored on external storage devices

• The concept of storing the processor inside the main memory

• The idea that program instructions and data values are held in the main memory and retrieved by the processor as required

• The method of controlling the flow of data between the CPU and the peripherals

What is the function of the Control Unit in the CPU?

• Performs operations on data values

• Holds frequently used instructions

• Synchronizes the operation of the computer

• Coordinates the other components

What does the Arithmetic Logic Unit (ALU) do?

• Temporarily holds data for operations

• Coordinates the other components

• Performs operations on data values

• Holds frequently used instructions

Which of the following is a function of the Clock in the CPU?

• Holds frequently used instructions

• Performs operations on data values

What is the purpose of Cache in the CPU?

• Synchronizes the operation of the computer

• Temporarily holds data for operations

• Coordinates the other components

• Fast memory used to hold frequently used instructions

Which type of register is used to temporarily hold data for operations?

• Dedicated

• Control Unit

• Cache

• General Purpose

What is the purpose of the Program Counter?

• To store the result of arithmetic operations
• To manage the input/output operations
• To control the flow of data between registers
• To keep track of the memory address of the next instruction to be executed.

What is the purpose of the Memory Address Register?

• To store the result of arithmetic and logic operations
• To hold the address of the memory location to be accessed next.
• To control the execution of instructions in the CPU
• To manage the flow of data between the CPU and memory

What is the purpose of the Memory Buffer Register?

• To temporarily store an instruction or data being transferred between memory and the CPU.

• To control the input/output devices
• To store the operating system files
• To regulate the clock speed of the CPU
