System programs provide various functions for managing files, retrieving system status information, modifying files, and enabling communication. These programs are not part of the OS kernel but are part of the overall operating system. They allow users to create, delete, copy, rename, print, dump, list, and manipulate files and directories. Other programs provide date, time, and detailed performance, logging, and debugging information. Additional programs like text editors are used to create and modify files, while communication programs enable connections between processes, users, and other computers.
