Embedded systems are machines that are built for a specific purpose and are completely enclosed within whatever it is these systems are controlling. This means that the software is embedded within the hardware allowing the designer to have more control over both the hardware and software of the machine in order to make it meet his or her expectations. Embedded systems can also be components of larger systems and carry out a specific task inside a greater system. For example, calculators, cell phones, printers are all examples of embedded systems.

            As mentioned before, embedded systems are made for a specific function and application and the programs on an embedded system are generally executed over and over. They are designed for real time, so they react to constraints and stimuli from their operator to give a real time response. They do this through many sensors that help them interact with the environment. This makes them reactive systems that are consistently in contact with the external world. As a result, many embedded systems either have minimal user interface or no user interface at all because of this interaction with the environment.

            Since embedded systems can be made for one specific purpose, their hardware can be simplified and therefore can be made more effectively and efficiently resulting in cheaper machines. This is why many kinds of embedded systems are mass produced and sold commercially. Some more advantages to embedded systems are the fact that they can generally withstand a wide variety of environments because they will not merely be sitting on a desk. Another benefit is that since they use less power than say a desktop computer, cooling is not needed quite as much and it is much easier to accomplish.
