What is an Embedded system? Differentiate between embedded system and real-time system.

Ans: An embedded system is some combination of computer hardware and software, either fixed in capability or programmable, that is specifically designed for a particular function.

It can be defined as “A specialized computer system that is part of a larger system or machine”.

Embedded systems are the ones found in generally immutable machines, such as ATMs, internet kiosks, airport terminal displays, cell phones,or at the screen at McD that displays your order are all examples of embedded systems. Real-time systems are the ones that are designed to provide a result within a specific time-frame. If you are using a touch-screen to order a sandwich from a gas store chain, you don’t want to have to wait 20 seconds for it to display pictures of each of the ingredients. You want it “now”, or at least within a second or two of pushing the button.
