   What is embedded system?

   • An embedded system is a specialized computer system —a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. [ 1 ][ 2 ] It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts.

   What are the characteristics of embedded systems?

   • From the inside, one of the most striking characteristics of embedded systems is severity of their constraints. Unlike writing software for a general-purpose computer, an embedded system is usually shipped already integrated with all the hardware it needs.

   What is the difference between a general-purpose computer and an embedded system?

   • Unlike writing software for a general-purpose computer, an embedded system is usually shipped already integrated with all the hardware it needs. The hardware platform is not usually user-extensible, so resources such as memory, power, cooling, or computing power contribute to the per-unit cost (known as recurring cost).

   What are examples of embedded systems?

   • Embedded systems tend to have one, or a limited number of tasks that they can perform. Examples of embedded systems include: Embedded devices are not usually programmable by a user - the programming is usually done beforehand by the manufacturer. However, it is often possible to upgrade the on an embedded device.
