Embedded refers to something that is tied to something else, as the name implies. A computer hardware system with software embedded in it is known as an embedded system. An embedded system can function as a stand-alone unit or as a component of a larger system. A microcontroller or microprocessor-based embedded system is a system that is designed to execute a certain task. A fire alarm, for instance, is an embedded device that can only detect smoke.
There are three parts to an embedded system: hardware, software, and peripherals.
It includes software for applications.
It has a Real Time Operating System (RTOS) that supervises application software and provides a mechanism for allowing the processor to conduct a process according to schedule by following a plan to control latencies. The system's behaviour is defined by the RTOS. It establishes the rules for the program's execution. RTOS may not be present in a small embedded system.
An embedded system might thus be defined as a Microcontroller-based, software-driven, dependable, real-time control system.
Embedded systems are hardware and software combinations. Embedded systems are designed to control a device, a method, or a broader system or framework. Embedded systems are all around us; they are present in every room. Embedded systems can control the basic units of a vehicle, telematics frameworks for traffic control, the chipset and programming in a set-top box for advanced TV, a pacemaker, chips in telecom switching equipment, ambient devices, and control systems embedded in nuclear reactors, to name a few examples. As a result of the embedded systems' broad appeal, job opportunities in the field are expanding.
The embedded systems course is designed to provide high-quality training to software developers and those seeking a career in this field. Students will learn how to design, implement, integrate, and test sophisticated embedded systems software in this course.

An embedded system is a computer system that is part of a larger system or machine. It is a system with a dedicated function within a larger electrical or mechanical system.
Computer systems that monitor, respond to, or control an external environment are known as real-time embedded systems. Actuators, sensors, and other input-output interfaces connect this environment to the computer system.
Microprocessor is managers of the resources (I/O, memory) which lie outside of its architecture
Microcontroller have I/O, memory, etc. built into it and specifically designed for control
The buses used for communication in embedded systems include
I2C: This protocol is used to communicate between numerous integrated circuits.
CAN: It's a network protocol that's utilized in cars with a centrally controlled network.
USB is a standard for communicating between a computer's processor and peripheral devices such as a mouse.
ISA, EISA, and PCI are parallel communication standard buses used in PCs, computer network devices, and other devices.
In a concurrent system, such as a multiprogramming operating system, a semaphore is an abstract data type or variable that is used to regulate access to a common resource by many processes. There are two main uses for semaphores. To be able to share a common recollection to grant others access to files.
