FEATURES OF MICROPROCESSOR

The three types of working of processor is as follows:-

1.Multi tasking:-It enables the processor to run multiple programs at a single time. As we know that the speed of processor is faster than the i/o devices so,it quickly switches to one program into other programs in such a way that it appearance like multiple tasking. In multiple tasking only one CPU is worked. In early period processor goes to rest after completing one instruction set or waiting for other but due to multi tasking features its performance,capacity of the system tends to increase.

e.g-like editing words and listening music.

There are also two types of multi tasking:-

• Preemptive:-It switch task between one to another without any permission. It may mainly apply on the same task open.

       e.g:-Any programme which use processor seperatly.

• Cooperative multi tasking:-In cooperative switching wants permission before switch.It may mainly apply on different task.Each programme in cooperative uses CPU for as long as need.

       e.g:-Installation and Uninstalltion of window,application.

2.Multi processing(parallel processing):-It is the technology used for the working of two processor in a single processor at a same time.It double the performance given by the system having one process unit.

3.Multi user:-More than single user can use the computer.It may more than one PC.

      e.g:-Remote access,destop connection etc.
