An NFS Server (Network File System Server) is a system that allows files to be shared over a network. It enables users to access files on remote computers as if they were on their own local machines. This is particularly useful in environments where multiple users need to collaborate and share data efficiently. The NFS protocol was developed by Sun Microsystems in the 1980s and is widely used in UNIX and Linux systems. It operates on a client-server model, where the server hosts the files and the clients request access. This setup simplifies file management and enhances productivity in networked environments.
