What is FTP, and how do I use it to transfer files?

Overview

FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network. You can use FTP to exchange files between computer accounts, transfer files between an account and a desktop computer, or access online software archives. Keep in mind, however, that many FTP sites are heavily used and require several attempts before connecting.

Note: You need to use a client that supports secure FTP to transfer files to and from Indiana University's central systems. For more, see At IU, what SSH/SFTP clients are supported and where can I get them?

How to use FTP

Graphical FTP clients

Graphical FTP clients simplify file transfers by allowing you to drag and drop file icons between windows. When you open the program, enter the name of the FTP host (e.g., ftp.empire.gov) and your username and password. If you are logging into an anonymous FTP server, you may not have to enter anything. Two common FTP programs are Cyberduck (for Mac) and WinSCP (for Windows). For more, see At IU, what SSH/SFTP clients are supported and where can I get them?

Web browser

You can use a web browser to connect to FTP addresses exactly as you would to connect to HTTP addresses. Using a web browser for FTP transfers makes it easy for you to browse large directories and read and retrieve files. Your web browser will also take care of some of the details of connecting to a site and transferring files. While this method is convenient, web browsers are often slower and less reliable and have fewer features than dedicated FTP clients.

To use your web browser to connect to an FTP site such as ftp.empire.gov, where you normally enter a URL, enter:

  ftp://username@ftp.empire.gov/

Command line FTP

Windows, Mac OS X, and Linux have built-in command line clients; see What are some common FTP commands? For example, to start FTP, at the command line prompt, enter:

   ftp ftp.empire.gov

If you are connecting to your own account, enter your username and password. If you are connecting to an anonymous FTP site, for your username, enter anonymous . For your password, enter your email address.

 

What is TCP/IP ?

TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, manages the assembling of a message or file into smaller packets that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination. Each gateway computer on the network checks this address to see where to forward the message. Even though some packets from the same message are routed differently than others, they'll be reassembled at the destination.

TCP/IP uses the client/server model of communication in which a computer user (a client) requests and is provided a service (such as sending a Web page) by another computer (a server) in the network. TCP/IP communication is primarily point-to-point, meaning each communication is from one point (or host computer) in the network to another point or host computer. TCP/IP and the higher-level applications that use it are collectively said to be "stateless" because each client request is considered a new request unrelated to any previous one (unlike ordinary phone conversations that require a dedicated connection for the call duration). Being stateless frees network paths so that everyone can use them continuously. (Note that the TCP layer itself is not stateless as far as any one message is concerned. Its connection remains in place until all packets in a message have been received.)

Many Internet users are familiar with the even higher layer application protocols that use TCP/IP to get to the Internet. These include the World Wide Web's Hypertext Transfer Protocol (HTTP), the File Transfer Protocol (FTP), Telnet (Telnet) which lets you logon to remote computers, and the Simple Mail Transfer Protocol (SMTP). These and other protocols are often packaged together with TCP/IP as a "suite."

Personal computer users with an analog phone modem connection to the Internet usually get to the Internet through the Serial Line Internet Protocol (SLIP) or the Point-to-Point Protocol (PPP). These protocols encapsulate the IP packets so that they can be sent over the dial-up phone connection to an access provider's modem. 

Protocols related to TCP/IP include the User Datagram Protocol (UDP), which is used instead of TCP for special purposes. Other protocols are used by network host computers for exchanging router information. These include the Internet Control Message Protocol (ICMP), the Interior Gateway Protocol (IGP), the Exterior Gateway Protocol (EGP), and the Border Gateway Protocol (BGP).

how it is possible without TCP/IP?

flow control, and error correction of data being sent across the network.Its main protocol is called the transmission control protocol (TCP). TCP provides reliable data delivery service with end-to-end error detection and correction.

Yes it is TCP/IP

Dear all,

Answer is FTP, it's clearly mentioned in the question i.e over internet. Internet in itself follows TCP/IP so to transfer file over TCP/IP, FTP protocol is required.

Basically FTP is part of the TCP/IP protocol suite. TCP/IP is the basic protocol that runs the whole Internet. Whether you are checking your email, visiting a web site or downloading files, you are using TCP/IP. There are a number of smaller protocols that run under the layer of TCP/IP, such as email, HTTP, and Telnet. FTP is one of these. File Transfer Protocol (FTP) is an application-layer protocol that enables files on one host, Computer B, to be copied to another host, Computer A. TCP provides a communication service at an intermediate level between an application program and the Internet Protocol (IP). FTP runs over the Transmission Control Protocol (TCP). FTP would not work without TCP/ IP over the Internet. The actual protocol for transmission is TCP/IP. I

I think the answer is D "TCP/IP"

Sir,

You are absolutely right.

Thanks
