Embedded systems are increasingly becoming integral parts of almost all technology-oriented applications. Embedded systems are the unsung heroes of much of the technology we use today- video games, washing machines etc. The appliances using embedded systems are pre programmed to perform a dedicated or narrow range of functions as part of a large system, usually with minimal end user interaction and optimum performance. Embedded systems are used in navigation tools like global positioning systems (GPS), automated teller machines(ATMâ„¢s), networking equipments such as Echo cancellation, facsimile etc. the coming together of embedded systems and the internet, which made possible the networking of several embedded systems to operate as part of a large system across networks- be it a LAN, WAN, or the Internet. This convergence of embedded systems with the Internet is going to transfer the way we live.
