Computer Science Stack Exchange. World Wide Web Consortium (W3C) Embedded system. An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.[1][2] It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.[3] Modern embedded systems are often based on microcontrollers (i.e CPUs with integrated memory and/or peripheral interfaces)[4] but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also still common, especially in more complex systems.

In either case, the processor(s) used may be types ranging from rather general purpose to very specialised in certain class of computations, or even custom designed for the application at hand.

COMPUTERSCIENCE1.tv. This is OpenCourseWare. Computer Science E-1 is a course at Harvard Extension School. E-1 isn't so much about computer science as it is about technology and how it all works. Most every student who takes this class uses computers every day but doesn't necessarily understand what's going on underneath the hood (or, in some cases, is outright scared!). All students exit this more comfortable with computers and the Internet. Even if you are not a student at Harvard, you are welcome to "take" this course via computerscience1.tv by following along via the Internet. (The course's own website is at www.computerscience1.net.) Available at left are videos of lectures along with PDFs of problem sets. If you're a teacher, you are welcome to adopt or adapt these materials for your own course, per the license.
