FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The steps of a machine cycle are: Fetch – The control unit requests instructions from the main memory that is stored at a memory’s location as indicated by the program counter (also known as the instruction counter).

Detailed explanation-2: -At the end of the fetch operation, the PC points to the next instruction that will be read at the next cycle. Decode Stage: During this stage, the encoded instruction presented in the instruction register is interpreted by the decoder.

Detailed explanation-3: -Four steps of the machine cycle Fetch-Retrieve an instruction from memory. Decode-Translate the retrieved instruction into computer commands. Execute-Execute the computer commands. Store-Send and write the results back in memory.

Detailed explanation-4: -In this process, the execution result is stored in memory. Once the Arithmetic logical unit operates on data, the result of the operation and processed data is sent to the main memory for the restoration of the result. The memory (RAM) is the main component in this process as the result is stored for later use.

Detailed explanation-5: -Ans : The instruction cycle consists of four phases: fetching an instruction from memory, decoding the fetched instruction, reading the address from memory, and finally, instruction execution.
