Memory, Software and Operating Systems PYQs
Every time you press a key, open a file or switch on a computer, a quiet chain of events begins: instructions travel from storage to memory, the operating system hands out the processor's time, and a program written in a human-friendly language is translated into the 0s and 1s the machine understands.
