State how many key named registers are there in the CPU?

• 3

• 4

• 5

• 6

The FDE cycle stands for?

• Find-Decrypt-Exe

• Fetch-Decode-Execute

• Find-Decode-Exe

• Fetch-Decrypt-Execute

The cycle the CPU preforms is known as:

• Fetch-Decode-Execute Cycle

• Fetch-Execute Cycle

• Instruction Cycle

• Data Processing Cycle

The CPU Von Neumann architecture introduced single stores of Data/Instructions known as _________

The part of the CPU that controls the flow of data and the FDE cycle is the:

• Control Unit

• Arithmetic Logic Unit

• Cache

• Registers

The part of the CPU that handles computational logic and mathematics is:

• Control Unit

• Arithmetic Logic Unit

• Cache

• Registers

The part of the CPU that is fast storage for the quick access is:

• Control Unit

• Arithmetic Logic Unit

• Cache

• Registers

The part of the CPU that is fast storage of a single value or instruction is:

• Control Unit

• Arithmetic Logic Unit

• Cache

• Registers

The main registers of the CPU are:

• Program Counter, Current instruction Register, Accumulator, Memory Address Register, Memory Data Register

• Program Current, Current instruction Register, Accumulator, Memory Adding Register, Memory Data Register

• Program Counter, Current instruction Register, Accumulator, Memory Adding Register, Memory Instruction Register

• Program Compiler, Current instruction Register, Accessing, Memory Address Register, Memory Instruction Register

Which register is described: The register holds the address of the next instruction to be executed. This ensures that the program runs in order and the correct thing is fetched for the next cycle.

• Program Counter (PC)

• Memory Address Register (MAR)

• Memory Data Register (MDR)

• Current Instruction Register (CIR)

• Accumulator (ACC)
