1 Answer

Answer :

An RTOS is an important subset of an embedded system. (See RTOS explanation below) An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions. The processor in these systems are also highly specialized. They are not, generally, the same processor you would find in a PC. A real-time operating system (RTOS) is intended for systems that need to tightly control responsiveness and performance. With
