Computer System Components Quiz

What are the two major components of the CPU?

• Input module and output module

• Arithmetic logic functions and input module

• Instruction interpreter and arithmetic logic functions

• Instruction interpreter and memory

What is the purpose of the input module?

• To execute programs sequentially

• To report results to the user

• To store data and instructions

• To convert data and instructions into internal signals

What is the function of the output module?

• To accept data and instructions

• To temporarily store instructions and data

• To report results from the system

• To execute arithmetic operations

What is the role of memory in a computer system?

• To execute programs

• To store only data

• To store only instructions

• To store both instructions and data

What does the memory address register (MAR) specify?

• The data to be written into memory

• The address in memory for the next read or write

• The specific I/O device

• The type of data being processed

What is the function of the memory buffer register (MBR)?

• To execute jump instructions

• To specify the address in memory

• To contain the data to be written into memory or received from memory

• To manage input and output devices

What does the I/O address register (I/OAR) specify?

• The type of arithmetic operation

• The data to be processed

• A particular I/O device

• The address in memory for the next read

What is the purpose of the I/O buffer register (I/OBR)?

• To convert data into internal signals

• To exchange data between an I/O module and the CPU

• To execute programs

• To store instructions

What does Von Neumann's architecture suggest about memory?

• It should only store data

• It is not necessary for a functioning computer

• It can store both instructions and data

• It should be separate for instructions and data

What is a key characteristic of program execution mentioned in the text?

• Programs always execute sequentially

• Programs do not require memory

• Programs only process one element at a time

• Programs can jump around during execution
