Think of cooking ackee and saltfish. The recipe (instructions) comes from a cookbook (storage). Your hands and brain do the chopping and frying (the CPU). You keep ingredients within arm's reach on the counter (RAM). The finished plate goes on the table (output). This is exactly what a computer does: INPUT, PROCESS, OUTPUT, STORAGE. We call it the IPOS cycle.
