Computer Architecture Quiz

What are the two major components of the CPU?

• Memory and I/O

• Instruction interpreter and arithmetic/logic unit

• Control unit and data bus

• Cache and registers

What is the purpose of an input module?

• To store data and instructions

• To execute instructions

• To accept data and convert it into a usable format

• To control the flow of data

What is the role of the output module?

• To receive and process input

• To display or store the results of computations

• To manage memory access

• To control the CPU

What is the purpose of memory in a computer system?

• To store data permanently

• To temporarily store both instructions and data

• To execute instructions

• To control input/output operations

What is the significance of the Von Neumann architecture?

• Using separate memory for instructions and data

• Using the same memory for both instructions and data

• Eliminating the need for memory

• Separating the CPU and memory

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

• To store data to be written to memory

• To receive data read from memory

• To specify the memory location for the next read or write

• To control the flow of data between the CPU and memory

What is the purpose of the MBR (Memory Buffer Register)?

• To store the address of the next instruction

• To hold data to be written to or read from memory

• To control the operation of the CPU

• To store the results of calculations

What are the two main steps of instruction processing?

• Fetch and execute

• Input and output

• Store and retrieve

• Encode and decode

What happens during the fetch cycle?

• The CPU executes an instruction

• The CPU reads an instruction from memory

• Data is transferred between memory and registers

• The CPU performs arithmetic operations

What happens during the execute cycle?

• The CPU reads an instruction from memory

• The CPU performs the operation specified by the instruction

• The CPU halts program execution

• Data is transferred to the output module
