Microprocessors are a mass storage device. They are the advanced form of computers. They are also called as microcomputers. The impact of microprocessor in different fields are significant. The availability of low cost, low power and small weight , computing capability makes it useful in different applications. Now a days , a microprocessor based systems are used in instructions, automatic testing product, speed control of motors , traffic light control , light control of furnaces etc.

Microprocessor based controllers are available in home appliances, such as microwave oven, washing machine etc.. Microprocessors are being used in controlling various parameters like speed, pressure, temperature etc.
It is very useful in the field of instrumentation. Frequency counters, function generators, frequency synthesizers, spectrum analyses and many other instruments are available , when microprocessors are used as controller. It is also used in medical instrumentation.
Microprocessors are being used in a wide range of communication equipments. In telephone industry , these are used in digital telephone sets. The use of microprocessor in television, satellite communication have made teleconferencing possible. Railway reservation and air reservation system also uses this technology. LAN and WAN for communication of vertical information through computer network
Microprocessor based micro computer with software packages has changed the office environment. Microprocessors based systems are being used for word processing, spread sheet operations, storage etc. The microprocessor has revolutionize the publication technology
The use of microprocessor in toys, entertainment equipment and home applications is making them more entertaining and full of features. The use of microprocessors is more widespread and popular.
because of low power consumption and accurate measurements we can use static relays based on microprocessor in power system networks. also filtering of noise is possible with static relays(based on microprocessor). also for continuous monitoring and security we can use these microprocessors. Filtering of noise is possible with static relays(based on microprocessor) Also for continuous monitoring and security we can use these microprocessors. There are actually 2 microprocessors in the phone: The processor and the baseband. The baseband controls wireless functions of the phone such as Bluetooth and telephone connection. This processor is a resource to the main processor which is used to control the user interface and higher-level systems of the Phone, such as applications that the user is likely to interact with

In washing machine we can see the options like 1. Set timings 2. Wash 3. Spin & rinse etc.... So in order perform all these options we need to program the MICRO CONTROLLER or MICROPROCESSORS to perform respective jobs. We program these processors in such a way that it has to recognize which job to be perform when user approach any of the above said options.
Microprocessors are used to control consumer electronic devices, such as the programmable microwave oven and DVD player; to regulate gasoline consumption and antilock brakes in automobiles. to monitor alarm systems and to operate automatic tracking and targeting systems in aircraft, tanks, and missiles and to control radar arrays that track and identify aircraft, among other defense application.
. Application of a microprocessor in a local intersection controller distributes the intelligence that was formerly concentrated in the central computer over an entire traffic network. This approach eliminates the limitations of the conventional traffic controllers. The central computer is now released of the direct traffic control and can be applied to optimize and to co-ordinate large traffic networks. An analysis of the basic operations executed in a traffic controller shows that they can be accomplished by special hardware as well as by a microprocessor with dedicated software routines.
A local traffic controller can now be developed by using a microprocessor, some specific I/O modules and a dedicated software package. Due to the flexibility of the software and a modular hardware approach it was possible to develop controller concept that could be applied stand alone or co-ordinate with neighbouring intersection controllers as well as supervised by a central computer. The latter is now free for selection of an optimal control strategy. The standard concept enables several local control strategies .
