A file server is a dedicated computer or device that stores and manages files for multiple users on a network. It allows users to access, share, and collaborate on documents and data from different devices, such as computers and smartphones. By centralizing file storage, a file server helps ensure that important information is organized and easily retrievable. File servers can be configured with various operating systems and software to enhance security and performance. They often support features like user permissions, which control who can access or modify specific files. This makes file servers essential for businesses and organizations that require efficient data management and collaboration among employees.
