1.1.1 Structure and Function of the Processor

What does MAR stand for?

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

The location of where data can be found in the computer memory is called the?

• Address
• Coordinates
• Register
• Cache

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

• Registers
• Addresses
• Cache
• Buses

MDR stands for Memory Delete Register

• True
• False

When the CPU fetches data it makes use of a vital path called?

• The Address walk
• The Address Bus
• The bus
• The address plane

Which of the following is a different computer architecture to Von Neumann's?

• Yale
• Harvard
• Stanford
• MIT

Which register is used by the ALU to temporarily store data?

• Accumulator
• MAR
• MDR
• PC

The stages required for processing are known as the....

• Fetch-Execute-decode
• Process-decode-fetch
• Fetch-Decode-Execute
• Process

What happens during the fetch stage?

• The CPU fetches data and instructions from main memory and stores them in its own registers.
• The CPU fetches instructions from the hard drive.
• The CPU fetches instructions from the ROM
• The CPU fetches data and instructions from the registers

What happens at the decode step of the fetch-decode-execute cycle?

• The CPU works out what the instruction that it has fetched actually means.
• This is where the instruction is processed.
• This is where data is fetched from the main memory.
• It is where the CPU transfers instructions from the memory.
