It includes Laptop , Notebook and person digital assistant (PDA)
2. Micro Computer:
These are single user computers. Micro computers are often called as Personal Computers ie. PC's.
3. Mini Computers:
They are medium level ,multiuser computers. as compared to mainframe computers , these computers operates at slower speed and have lesser memory. These computers are used by insurance companies , Banks , Factories to keep records.
4. Mainframe Computers:
mainframe computers are expensive , large centralized computers. It is multiuser computer and have has large memory. it is capable of having speeds of the order of several billions of floati-point operations per second.
These computers are used for Railway Reservation and for Railwaysuch other works.
5. Super Computers:
Super computers are extensively used for solving very large computational problems in scientific research , engineering , industry , defence and business for variety of applications like molecular dynamics , aerospace ,nuclear -weapons , seismic studies , oil-explorations , geology.
