In a CPU based on the von Neumann architecture, registers are dedicated high-speed storage locations. State the two CPU registers that are specifically used to hold instructions (either the instruction currently being decoded or the instruction newly retrieved from memory) during the Fetch-Decode-Execute cycle.
Practise Edexcel GCSE Computer Science Hardware with exam-style questions for GCSE Computer Science. 97 questions covering Von Neumann architecture and FDE cycle, Secondary storage devices, and Embedded systems, matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
