24、 are two kinds of mon digital puters.Microputers,also called personal puters,are thenewest puters.Many are aboutthe size of a very small television set.Some,however,are so small and light that peoplecan carry them easily on business trips.Because puter manufacturers produce anenormous amount of pute

26、and cannot do.Some experts say that almost half of allmicro-puters are not used often because their owners do not spend enough timelearning how to operate them efficiently.Like microputers,miniputers are used in small businesses.However,they arelarger than microputers and are used more frequently in
27、 large offices and businessesthan in small businesses.Another difference is thatmore than one person can use aminiputer at the same time.We call this time-sharing.Some miniputers can have morethan a hundred people time-sharing them.Each person who uses a miniputer has a.可修编.-puter terminal that is c
