Other Computers Microcomputers are the type of computers that we are most likely to notice and use in our everyday life. Mainframe computers are used when you access your bank account from a automated teller. The bank's mainframes handle all the transactions. Workstations are computers that are bigger than micros and have the power of mainframes. They are typically UNIX computers and are used by engineers for more computationally difficult tasks.
Laptop computers are increasingly popular because they are portable and can run on batteries.
A PDA is typically small enough to carry around in a pocket.
