WebJan 13, 2024 · The basic operation of a computer is called the ‘ fetch-execute ’ cycle. The CPU is designed to understand a set of instructions – the instruction set. It fetches the instructions from the main memory (RAM) and executes them. This is done repeatedly from when the computer is booted up to when it is shut down. WebFETCH The CPU reads the contents of the Program Counter to find the address of the next instruction to be fetched, decoded and executed. In our case 3254. As soon as it is read, the PC increments. PC = PC + 1, or 3255 The contents of 3254 are then put on the MAR. The address in the MAR is then located in RAM.
