Final answer:
To check for Git installation, open a terminal and enter the command 'git --version'. If installed, it displays the Git version; otherwise, an error message will appear indicating that Git is not found.
Step-by-step explanation:
To check if you have Git installed on your system, you can open a terminal (Command Prompt on Windows, Terminal on macOS, or the terminal app on Linux distributions) and type the following command:
git --version
If Git is installed, you should see a message displaying the installed version of Git, such as:
git version 2.24.0
If Git is not installed, you will receive an error message indicating that the 'git' command could not be found. In this case, you would need to download and install Git from its official website or through your package manager if you are using a Linux distribution.
