What is a mainframe computer?

-Is computer software designed to help the user to perform specific tasks.
What is BPS?

What is a packet?

What is a protocol?
-Is a system of digital message formats and rules for exchanging those messages in or between computing systems and in telecommunications.
What is a magnetic disk?
-A memory device, such as a floppy disk, a hard disk, or a removable cartridge, that is covered with a magnetic coating on which digital information is stored in the form of microscopically small, magnetized needles.
