A file descriptor is an abstract representation of a file or other input/output resource. It is used by operating systems to manage resources such as files, sockets, pipes, and devices. A file descriptor contains an integer value that uniquely identifies the resource and other information such as the file offset, access mode, and status flags. It does not usually contain the file name or directory name.
