Show the answer and mark scheme

  • 8(a)[2]

    Any two from:

    Data is stored on platters
    (Platters) are divided into tracks and sectors
    Has components that are spun
    Data is read/written using a read/write arm
    Data is read/written using electromagnets
    Magnetic field determines the binary value
    It is non-volatile

  • 8(b)[3]

    Any three from:

    Flashes data onto chips
    Uses transistors
    Uses NAND/NOR technology
    Uses control gates
    Uses flow gates
    Controls the flow of electrons
    It can be volatile or non-volatile

  • 8(c)[3]

    One mark for an example in each storage type e.g.:

    Magnetic

    HDD
    Magnetic tape
    Floppy disk
