Question
In a three-cycle instruction execution model, which of the following machine cycles is not present? A) Fetch B) Decode C) Execute D) Encode
Solution
The answer is D) Encode. In a three-cycle instruction execution model, the three cycles are: Fetch, Decode, and Execute. The Fetch cycle retrieves the instruction from memory. The Decode cycle translates the instruction into a form that can be used by the Execute cycle. The Execute cycle performs the operation specified by the instruction. The Encode cycle is not part of this model.
