ITPEC FE Morning April 2021 Question 13
ITPEC FE Morning April 2021 — Question 13 of 80
Stored Program Architecture — the CPU sequentially reads and executes instructions stored in main memory (von Neumann architecture).
The key idea: both program instructions and data reside in the same main memory, and the CPU fetches them one by one in sequence.
Why not others:
- (a) Addressing system — a method for specifying memory locations (direct, indirect, indexed), not an architecture
- (b) DMA control architecture — allows peripherals to access memory bypassing the CPU, the opposite concept
- (d) Virtual memory system — extends physical memory using disk swap space, unrelated to sequential execution
Key rule: "Stored program" = von Neumann architecture = instructions stored in main memory and executed sequentially by the CPU.
