The computer is one of the most powerful innovations in human history. With the use of computers, people are suddenly able to perform a staggering amount of computations at dazzling speeds. Information can be crunched, organized, and displayed in the blink of an eye. As technology continues to advance, the computer will no doubt become even more pervasive and in many cases, likely even less recognizable.
Computer like this is often referred to as an embedded computer. An embedded computer is differentiated from a personal computer because it is essentially static in its function. While a personal computer, or some cellular telephones, or some personal organizers are able to have new software installed, and make use of a wide range of features, an embedded computer usually has only a few purposes, which are relatively fixed once the computer is manufactured.
