What is FTP? How does it Work? Requirements of using FTP? with configurations

      

what is FTP :- What if you want to copy files from one computer to another that is halfway around the world?  You would probably use your Internet connection.  However, for security reasons, it is very uncommon to share folders over the Internet.  File transfers over the Internet use special techniques, of which one of the oldest and most widely-used is FTP.  FTP, short for "File Transfer Protocol," can transfer files between any computers that have an Internet connection, and also works between computers using totally different operating systems.

How does File Transfer Protocol Work: - When files are transferred through FTP, one of two actions is happening – uploading or downloading. Uploading involves transferring files from a personal computer to a server. Downloading involves transferring a file from a server to a personal computer. FTP uses TCP/IP (Transmission Control Protocol/Internet Protocol) to transfer your files. TCP/IP is basically the language that the Internet uses to carry out commands.
If you are going to use File Transfer Protocol in order to download files, you should keep security concerns in mind. Files downloaded from the Internet may have viruses that can harm your computer.
One way to use FTP is to go through an FTP client. FTP clients may make it safer for your computer to download/upload files and help you avoid malware and viruses. Some FTP clients are pricey, while some are completely free. Using an FTP client is not a necessary step for transferring folders, but it may make uploading and downloading files easier to do.
