The term "System Root" refers to the main directory in a computer's file system where the operating system is installed. It serves as the starting point for accessing all other files and folders on the system. In many operating systems, such as Windows or Linux, the System Root is typically represented by a specific drive letter or path, like C:\ for Windows. In a broader context, the System Root contains essential system files and directories that are crucial for the operating system's functionality. This includes folders like Program Files, Windows, and System32 in Windows, which house applications and system resources necessary for the computer to operate effectively.
