Many people have heard of Linux, but most don’t really know what it is. Linux is an operating system that can perform the same functions as Windows 10 and Mac OS. The key difference is that Linux is open source. In the most simple terms, it just means that no one single person or corporation controls the code. Instead, the operating system is maintained by a dedicated group of developers from around the world. Anyone who is interested can contribute to the code and help check for errors. Linux is more than an operating system; it is a community.
