Memory & Storage: Crash Course Computer Science #19
Pre-order our limited edition Crash Course: Computer Science Floppy Disk Coasters here! https://store.dftba.com/products/computer-science-coasters
So we’ve talked about computer memory a couple times in this series, but what we haven’t talked about is storage. Data written to storage, like your hard drive, is a little different, because it will still be there even if the power goes out - this is known as non-volatile memory. Today we’re going to trace the history of these storage technologies from punch cards, delay line memory, core memory, magnetic tape, and magnetic drums, to floppy disks, hard disk drives, cds, and solid state drives. Initially, volatile memory, like RAM was much faster than these non-volatile storage memories, but that distinction is becoming less and less true today.
CORRECTION: AT 5:00 we say "around 9 kilobytes" when we should have said "kilobits".
