The machine cycle is the process a computer uses to carry out program instruction from its memory, determine what actions the instruction requires, and carry out those actions. The four basic operations are:Fetch: Instructions are retrieved and data is input from memory.Decode: Instructions and data are examined and decoded, and then sent to the arithmetic/logic unit (ALU) for processing.Execute: The ALU executes the calculation with the data.Store: Results from the ALU calculation are stored in memory.
