An embedded system combines computer software and hardware to perform a specific function. Embedded systems can also work as part of a more extensive system. The designs can be programmable or fixed in position. An embedded system could be installed in agricultural and industrial machines, consumer electronics, processing industry devices, automobiles, medical equipment, cameras, digital watches, household appliances, vending machines, aeroplanes, toys, and mobile devices.
In this article, we will talk about What it is an Embedded System and what its characteristics are.

What is an Embedded System?
An embedded system is a microcontroller or microprocessor-based system programmed to perform a specific function.
When classifying embedded systems based on microcontroller performance, embedded systems are divided into three categories:
- Small-scale embedded systems.
- Medium-scale embedded systems.
- Sophisticated embedded systems.
How does an Embedded System work?
The term embedded refers to systems that always operate as a component of a larger device. They are small, low-cost computers embedded in other mechanical or electrical systems. They typically include a processor, a power supply, memory, and communication ports. Embedded systems use communication ports to send data between the processor and peripheral devices, which are frequently other embedded systems, via a communication protocol. The processor interprets this data using minimal software stored in memory. The software is usually highly tailored to the function of the embedded system.

In real-time operating environments, embedded systems communicate with hardware via a real-time operating system (RTOS). Near-real-time approaches are appropriate at higher levels of chip capability, as defined by designers who have increasingly determined that the designs are generally fast enough and the tasks are tolerant of minor variations in reaction time. Stripped-down versions of the Linux operating system are commonly used in these cases. However, other operating systems, such as Embedded Java and Windows IoT, have been reduced in size to run on embedded systems (formerly Windows Embedded).
Characteristics of Embedded Systems
The primary distinguishing feature of Embedded Systems is that they are task-specific. The following characteristics can be found in Embedded Systems:
- It can be embedded in a more extensive system to perform a specific function because it is designed for specialised tasks rather than multiple tasks.
- It can be either microprocessor- or microcontroller-based; both are integrated circuits that provide compute power to the system.
- It is frequently used for sensing and real-time computing in the internet of things (IoT) devices, which are internet-connected devices that do not require a user to operate.
- It varies in complexity and function, influencing the software, firmware, and hardware used.
- They are frequently required to perform their function under time constraints to keep the more extensive system running smoothly.
