We use computers every day, but how often do we stop and think, “How do they do what they do?” This video series explains some of the core concepts behind computer science.
This session traces the development of operating systems from the Multics and Atlas Supervisor to Unix and MS-DOS, and takes at look at how these systems influenced popular OSes we use today.
Memory and storage are different things but both hold data in your computer. While memory is temporary, storage remains even in a system without power.
