Cards in this deck (20)
- 1Which logic operations can the ALU perform? (Tick all that apply)AND
OR
NOT Binary shifts - 2In the CPU, this is a register which holds the memory address of the next instruction to be run/fetched.Program counter
- 3Which part of the CPU is responsible for executing program instructions by following the fetch-decode-execute cycle?Control unit
- 4The area of the CPU which stores regularly used data is known asThe cache
- 5Which part of the CPU will control the flow of data by sending signals inside and outside of the CPU?Control Unit
- 6In the CPU, this is a register which stores the intermediate results of the ALU.Accumulator
- 7A dual core processor willHave 2 processors which perform the fetch, decode, execute cycle simultaneously. This means more instructions can be carried out at once, making it faster.
- 8The amount of times your CPU can complete the fetch-decode-execute cycle is known asThe clock speed
- 9Out of the 3 levels of cache, which is the correct order for capacity? (Highest to lowest)L3 cache, L2 cache, L1 cache
- 10Which part of the CPU will be used to decode the instruction stored in the memory data register (MDR)?Control Unit (CU)
- 11Which is not a register of the Von Neumann architecture?Control Unit
- 12Which register which holds the actual data or instruction fetched from memory or waiting to be written to memory?Memory data register (MDR)
- 13This component will fetch, decode and execute data and instructions.CPU
- 14Which calculations can the ALU perform?Subtraction Addition
- 15Out of the 3 levels of cache, which is the correct order for speed? (Fastest to slowest)L1 cache, L2 cache, L3 cache
- 16Which part of the CPU is responsible for doing all of the calculations?Arithmetic and logic unit
- 17Which part of the CPU would you expect to find the accumulator register?Arithmetic and logic unit
- 18The higher the clock speed�The greater number of instructions that can be carried out per second.
- 19Which part of the CPU would you expect to find the program counter register?Control Unit
- 20Which register holds any memory address where the data is about to be fetched/written?Memory address register (MAR)
