To find the shell on a computer, you can open a terminal or command prompt application. In Windows, you can use Command Prompt or PowerShell, while in Unix-based systems (such as Linux or macOS), you can use the Terminal application. These applications provide a command-line interface to interact with the operating system.

A shell in Linux is the interpreter that provides a commandline interface (CLI). There are many kinds of shells.
I am assuming you mean either a POSIX shell or a way to SSH into a Linux box. A POSIX shell is as simple as installing MinGW, which will usually also provide BASH, usually for scripts. For SSH you can just use PuTTY and connect to your Linux box (Assuming it has an SSH server running.) that way.
The Z shell is a Bourne-compatible shell for Linux and Unix systems.
bash (Bourne Again Shell) is the default shell in most Linux distributions. It was created as part of the GNU project.
echo $SHELL
Shell is the bridge between Kernel and User.
Strictly speaking, a "shell" is simply the interface between the user and the rest of the operating system. In that definition not all shells on Linux are command lines. However, most day-to-day usage of the term "shell" does refer to command line user interfaces. Finally, "Linux shell" is not a thing. Linux is an operating system, specifically a kernel, not a shell. Most Linux distributions use BASH, but I personally prefer ZSH.
The courses available for Linux include Linux server, Linux desktop, bash shell, and many others.
