Question 5

What is Von Neumann architecture used for

Answer 5

Data and instructions are both stored as binary
Data and instructions are both stored in main memory
Instructions are fetched from memory one at a time and in order - serially
The processor decodes and executes an instruction, before cycling around to fetch the next
instruction (fetch-decode-execute cycle)
The cycle continues until no more instructions are available
