What is a FDE cycle within a CPU?

Answer 1

The FDE cycle, which stands for Fetch-Decode-Execute cycle, is the fundamental process by which a CPU operates. During the fetch phase, the CPU retrieves an instruction from memory. In the decode phase, the CPU interprets the instruction to understand what actions are required. Finally, in the execute phase, the CPU carries out the instruction, which may involve performing calculations, moving data, or interacting with I/O devices. This cycle repeats continuously to process instructions in a program.
