Key Points
- The instruction cycle is the process by which a computer retrieves, decodes, and executes an instruction.
- The correct sequence of operations is:
- Fetch the information (B): The instruction is fetched from memory.
- Decode the instruction (D): The fetched instruction is decoded to understand the operation to be performed.
- Read the effective address (A): The effective address of the data required for the operation is determined.
- Execute the instruction (C): The instruction is executed and the desired operation is performed.
Additional Information
- The instruction cycle is fundamental to the operation of all computers and involves multiple steps to ensure that the correct operations are performed accurately.
- Each step in the cycle is crucial for the correct execution of instructions, ensuring that the computer processes data efficiently.
- Understanding the instruction cycle is important for those studying computer architecture and assembly language programming.
