An embedded device is a hardware and software system that performs a dedicated function within a larger computer system. It is typically resource-constrained and comprises a processing engine. The software of an embedded Linux system runs on top of the Linux kernel, the fundamental core of the OS with complete control over everything occurring in the system. It follows an embedded Linux system simply denotes an embedded system running on the Linux kernel.

The Linux kernel is a member of the family of Unix-like OS kernels, with AT&T Bell Labs devising the first version of Unix back in 1969. Being proprietary, Unix, the first portable OS, stimulated the development of free and open-source alternatives like Linux and, among the many others, FreeBSD, NetBSD, and OpenBSD1.

Linux is the premier choice by developers of embedded applications for several reasons: from being open-source to scalability, developer support, and tooling, myriad arguments justify why Linux is a great candidate for embedded systems. Linux runs on many hardware platforms because developers ported the kernel to several CPU architectures. Instead of being restricted to a specialist programming language in an industrial setting and compared to native microcontrollers programming, with Linux also comes extensive support for languages. Linux implements a rich stack of networking protocols, it is highly scalable, open-source with extensive community support, and you can deploy it with no royalties1.
