Embedded System is a programmed computer system, which is only to create or perform a specialized set of functions. It is not like for general purpose computer system or a laptop to perform such a high level capabilities and flexibility which allow the user to do multiple functions same moment. The embedded technology system often provides limited interface and allows to performing one or more tasks. Nowadays, Embedded System are capable for touch panel module systems and high degree user interface such as these used in research equipments, security purpose, medical, railway and more. The embedded system was firstly used in spacecraft programs in 1960s. Today the system have become spread everywhere. Now almost every organization/ industry uses the technology to produce the electronic and digital device.
Embedded system will be a standalone or a subsystem device of a big mechanism. If a digital watch use a simple standalone and can perform a function which is pre-performed functions at that time a car use subsystem/complex inbuilt system. These systems are able to perform various functions like power windows, antilock, engine controls, brakes, power seat etc. Basically these systems are by multiple networks and controlled by a central module. Giving some more examples where embedded systems used:-

Giving some more examples where embedded systems used:-
- Pressure sensor
- Electrical safety monitor
- Thermostat
- Security camera
- Indoor/outdoor temperature sensor
- SCADA System
- Measuring devices
Nowadays, many consumer products use simple Embedded System microprocessors which have low memory storage. They have applications and operating systems which are incorporated into single system module. The systems program is stored in the device Random Access Memory. Even embedded systems are build into devices & machineries which is subjected to heavy usable systems for many years, and ensure that they can quickly recover and automatic system rest.
