Embedded Systems
An Embedded Systems is a kind of computer that is custom made and is inbuilt to perform only a certain type of function.
Introduction:
Very far removed from a Personal Computer, the Embedded Systems is a type of computer that runs Computer Software Applications. The Embedded Systems, however, is very different from a Personal Computer. While a Personal Computer is designed to multi task and operate diverse functions belonging to different levels, Embedded Systems are developed for the purpose of only carrying out specific and pre-defined tasks.
An Embedded System is basically a ‘Special Purpose Computer’. Today, there are numerous types of Embedded Systems. Among them is the Physically Embedded Systems. A Physically Embedded System is a device that is portable. The likes of this kind include objects like digital watches, MP3 players, traffic lights, or even factory controllers.Another fact about Embedded Systems is that they are always mass produced.

History of Embedded Systems:
When computers came into the market in the 1940’s, they were all Embedded Systems. However, they were never regarded as Embedded Systems because, firstly, they were regarded as computers; and secondly, because they were too large and uncouth to be formally termed as Embedded Systems.
The Apollo Guidance Computer changed history. It became the world’s first modern Embedded System. The Apollo Guidance Computer was developed by Charles Stark Draper. The size of the device was reduced considerably from its monolithic ancestor. However, this increased other risk factors.

Mass production of Embedded Systems began in the year 1961 with the Autonetics D-17.Ever since, there has been no stopping the production and increase in the use of Embedded Systems.
