What is the difference between Unix and Linux?

It is often treated as ** Unix-like OS ** in the same category, but it is actually divided into two types, Unix-like and Linux-based, as shown below.

--Unix: BSD, Solaris, AIX, HP-UX, Mac OS ...

--Linux: Red Had Enterprise Linux, Debian GNU, Ubuntu ...

The difference between the above two systems is ** " Whether Linux is used for the kernel part " **.

--Unix: Linux is not used for the kernel part

--Linux system: Linux is used for the kernel part.

Each Linux distribution builds its own OS on top of a kernel (the core of the OS) named Linux, which is open source. The name of each of these distributions is what is commonly referred to as the Linux OS name (Red Hat, Debian, Ubuntu, etc.).
