Apart from these in the medical sector, it provides a great helping hand in storing information that could be referred later, in space technology, automation in banks, ticket booking through the net, traffic control, and even games could be played in computers on and many more. Computer systems are also designed for their purposes, and each environment will require a different computer system. Initially we will focus on process scheduling. Thermal, Ink Jet, Daisy wheel, Thimble, Spark, Drum, Chain and Laser printer. This can include controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked by outside personnel to place the system in a compromising situation.
