• Cheaper to desing
  -Limits numbers of funtions

Question 10

Name the process of the FDE cycle

Answer 10

1) Processor cheaks the PC to see which instruction to run next

2) PC gives an address value in the memory of where the instruction is

3) Processor fetches instruction value in the memory location

4) Once instruction has been fetched it need to be decode and execute

5) Once this is complete the processor incriminate (goes up by +1)

6) The cycle repat till the program ends.
