Embedded Systems
An embedded system typically has a specialized function with programs stored on ROM. An embedded system is a system within a larger system. It is often implemented on a single integrated circuit or as scaled-down software code. Examples of embedded systems are chips that monitor automobile functions, including engine controls, antilock brakes, air bags, active suspension systems, environmental systems, security systems, and entertainment systems. Everything needed for those functions is custom designed into specific chips. No external operating system is required.
Network managers will need to manage more and more embedded systems devices, ranging from printers to scanners, to handheld computing devices, to cell phones. All of these have a need to connect with other devices, either directly or through a wireless or direct-connect network. If the weather station is connected to the Internet, it may have its own IP address and, ideally, will provided information to anyone that accesses the IP address. In this sense, the weather station is acting as a mini-Web server. In fact, many embedded systems are basically Web servers on a chip. The chip contains HTTP and HTML functions, and custom applications appropriate for the environment in which the chip will be used.
