14. Microcomputers are used when traveling they have alotlessspeed andpower than a mini computer ormainframe.Mainframe computers are large and have more power and speed than a mini computer and that arecapable of quickly processing very large volumes of data.Special purpose computers are designed for specific tasks.Minicomputers are a category ofcomputers with lesspower and speed than amainframe but that are capable of storing and processing large volumes of data.
15. A portable one is made for traveling and are always inferior to a personal computer which are bigger and meant to stay at one spot.
