In conclusion, Linux is written in C. This is one of the reasons why it’s so popular and versatile. C is a powerful language that allows for efficient and low-level programming, making it ideal for writing the Linux kernel. It’s also relatively easy to learn and there are a lot of developers who are familiar with it. And since C is a portable language, it’s relatively straightforward to port Linux to different hardware platforms. All of these factors make C an ideal choice for writing the Linux operating system.
