FTP: File Transfer Protocol

FTP is an abbreviation of the File Transfer Protocol. FTP is a standard network protocol used in transferring files between systems of computers from a client to the server over a TCP/IP network. It is assembled on a client-server architecture and a basis of the Application layer. The client commands the conversation, while the server transfers the content of the file. The starting of the conversation is held by a browser that acts as a client and by making some appeals on the server side it communicates over the network. A client can remove, download, delete, or upload files on a server through FTP.

The transferring of a file from a client to the server is called "Uploading" and transferring of a file from server to the client is called "Downloading". Therefore, it is commonly used to process uploading files to a server using the internet and to process downloading files from a server over the internet.

Active and Passive Connection Mode

  • FTP works in a passive and active both types of mode.
  • In the case of active mode, the client instigates a request to the server and the server acknowledges back through connecting data and transmitting data.
