Embedded system

An embedded system can be looked at as one or more computer chips or automated devices involving computer programs, microcode, firmware, ROM, PROM, and EPROM program code. Once the logic is burned into the chips, it cannot be changed. These automated devices typically perform their intended functions over long periods of time without error, unless there is a physical defect in the code. However, automated devices and embedded systems are really “limited function computers” and are subject to many of the same vulnerabilities as their “full function computer” counterparts.
