In computer architecture, the fundamental process of executing s occurs in a series of s known as the -- . This cycle is the backbone of a 's operation and involves several crucial stages. The first stage is the Fetch step, where the CPU s the next instruction from . The instruction, which is stored in memory, contains a of binary codes that represents a specific operation to be carried out.
Throughout the whole , the CPU interacts with the memory to retrieve and store data as required by each instruction. The memory stores both the instructions themselves and the data that is being manipulated by those instructions. The CPU regularly accesses the memory to ensure the instructions and data are available whenever needed.
The Fetch-Decode-Execute cycle continues until all the instructions in a program have been executed. The CPU repetitively performs this cycle, stepping through each instruction in a logical sequence. By following this cycle, the CPU sequentially retrieves, decodes, and executes instructions, ensuring the orderly execution of a computer program. This process enables the CPU to effectively complex tasks while utilizing the resources in an efficient manner.
