Von Newwman Flashcards
What are the three elements involved with the Von Newmann Architecture?
Fetch-decode-execute
Where is the accumulator found?
Within the ALU
What does the memory address register do?
Stores the address for the next piece of memory
Which type of bus is used to connect the cpu and the memory?
Bidirectional
Which of the components of the architecture isn’t a register?
The control unit
What does the program counter contain?
The memory address for the next instruction
What does the process “fetch” consist of?
“Fetching” instructions from the RAM to the cpu
What does the process “decode” consist of?
The control unit receives the instructions and decides what to do with them
What does the process “execute” consist of?
The instruction is carried out
What are registers?
High speed storage areas within the cpu (not cache!)
What does the address bus do?
Carries the address of the data but doesn’t carry the actual data
What does the data bus do?
Carries the data between the processor and the memory unit and the input/output devices
What does the control bus do?
Carries control signals/commands from the cpu to control the activities within the computer (peripherals)
