Chapter 12. Embedded Devices > Where Are Embedded Systems?

Where Are Embedded Systems?

The first point of interest is that embedded systems are everywhere! We tend to identify with the computers that we see on our desk or on our laps because they offer an easy way to identify them: They have a display. However, we have an “out of sight, out of mind” kind of attitude regarding the other systems that don’t have an obvious computer display. Because we don’t “see” them, we tend to forget that they’re even there. For example, the automated teller machine (ATM) is an example of an embedded system that you run across every day.

Another example of an embedded system is your printer, as shown in Figure 12-1. Your printer most likely has an embedded controller in it that manages data coming from the Ethernet, provides a Web-based interface, and manages the print engine. If your printer is a network printer, it does have an embedded controller because it will also have a Web interface on it for remote management. Checking your printers is easy; just try to browse to your printer’s address! If you get a Web page, there’s an embedded system in your printer.
