Application Layer
The TCP/IP Application layer includes protocols for e-mail, remote logins, file transfers, Web browsing, network management, and name management.
- FTP: The File Transfer Protocol (FTP) sends data over a reliable connection. This protocol can be used to send, delete, and move files to and from an FTP server and client.
- TFTP: The Trivial File Transfer Protocol (TFTP) sends data using an unreliable connection. This protocol functions similarly to FTP, but is faster because it is not reliable. Unfortunately, a file transferred with TFTP stands a greater chance of being corrupted than if it were transferred with FTP.
- NFS: The Network File System is a distributed file system that allows data to be shared across a network, regardless of the type of computer, operating system, network architecture, or protocol. This standard UNIX file system allows remote files to be manipulated.
