The Fetch-Decode-Execute Cycle is the fundamental operational process of a computer's central processing unit (CPU) that retrieves instructions from memory, decodes them to determine the required action, and then executes them to perform tasks. This cycle is repeated continuously by the CPU to process instructions and manage data flow within a computing system.
