Eih server files download

File Transfer Protocol: The FTP is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet. It uses port number 21.

FTP is built on server-client architecture and uses separate control and data connection between the client and the server.

FTP uses many authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can be connected anonymously if the server is configured to allow it.

Network File System (NFS): NFP is a distributed file system protocol allowing a user on a client computer to access a file over a network much like local storage access. It allows two different types of the file systems to interoperate. It has a different version: NFS2, NFS3, and NFS4. NFS protocol uses port number 2049.

In the NFS environment, a Windows server running NFS Server Software and the UNIX host running the NFS client software allows us to store the UNIX file which can be accessed by UNIX users. Hence both UNIX users and Windows users with Windows file system and UNIX file system can access that same file with their normal file system, in their normal way.

Post Office Protocol (POP): In computing, the POP is an application-layer Internet standard protocol used by local e-mails clients to retrieve email from a remote server over a TCP/IP connection. It is also known as an incoming address. POP has been developed through several versions with version 3 (POP3) being the latest one.

Email clients using POP generally connect, retrieve all messages, store them on the user’s PC as a new message, delete them from the server, and then disconnect. Most POP clients have an option to leave mail on the server after the download.

A POP3 server listens on well-known port 110 or Secure Socket Layer (SSL) on well-known port 995.
