The program instructions are represented in binary and stored in the ........... from which they are fetched, decoded and executed by the CPU.
Answer: A) memory
Program instructions are stored in binary format in memory, from where the CPU fetches, decodes, and executes them. This is a fundamental principle of computer architecture known as the fetch-decode-execute cycle. Memory (RAM/ROM) provides temporary or permanent storage for data and instructions, while a chip or control unit are specific components of this process. The CPU directly retrieves instructions from memory, not from a chip or control unit, making memory the correct answer. -
