What is serial random and parallel access What types of storage devices use each method Which ones do you use on your computer?
Serial- reads and writes in sequence. Like a cassette tape and maybe a floppy not sure.
Random- Can read and write between non continuous data. CD, DVD.
Parallel-reads and writes portions of data in parallel using separate lines or mediums. Such as an Ethernet cable- its made up of about 8 wires each wire sends a bit of data parallel with 7 other bits to send 8 total bits in parallel .
