Von Neumann Architecture

According to the von Neumann model, _______ are stored in memory.

• only data

• only programs

• data & programs

• neither data nor programs

Which of these are REGISTERS in the CPU? (Tick ALL that are correct)

• Accumulator

• ALU

• Program Counter

• Memory Address Register

• Control Bus Register

What does MAR stand for?

• Main Address Register
• Memory Address Register
• Massive Address Register
• Minimal Age Readable

Tick all options that happen in the FETCH CYCLE?

• PC is incremented

• The Instruction at the MAR address is read from RAM

• The PC value is copied to the MAR

• The instruction in the MAR is decoded

• The value in the MDR is written to the address in the MAR.

Tick all options that happen in the DECODE CYCLE?

• PC is incremented

• The Instruction at the MAR address is read from RAM

• The PC value is copied to the MAR

• The instruction in the MAR is decoded by the CU

• The value in the MDR is written to the address in the MAR.

Tick all options that happen in the EXECUTE CYCLE?

• PC is incremented

• The data at the MAR address is read from RAM

• The ALU performs any calculations required on the ACC

• The instruction in the MAR is decoded by the CU

• The value in the MDR is written to the address in the MAR.

The idea developed in 1945 by Von Neumann of a computer holding both programs and the data used by the programs in memory is called the..?

• Stored Program Concept
• Memory Program System
• Stored Memory Concept
• Stored Memory Program

The small high speed storage areas within the memory and processor are known as..?

• Registers
• Addresses
• Cache
• Buses

The Program Counter

• Stores the address of the next instruction in memory

• Stores the address of where the next item will be fetched from

• Stores data fetched from memory, or waiting to be stored in memory

• Stores the result of arithmetic calculations

Accumulator

• Stores the address of the next instruction in memory

• Stores the address of where the next item will be fetched from

• Stores data fetched from memory, or waiting to be stored in memory

• Stores the result of arithmetic calculations
