The FTP client using the URL gives the FTP command along with the FTP server address. Whereas the data channel is used to actually transfer the data between client and server. It uses the NVT ASCII character set for communication. FTP uses the same approach as TELNET or SMTP to communicate across the control connection. The command channel is used to transfer the commands and responses from client to server and server to client. When an FTP connection is established, there are two types of communication channels are also established and they are known as command channel and data channel. So, for the connection, the user can get permission by providing the credentials to the FTP server or can use anonymous FTP. The FTP connection is established between two systems and they communicate with each other using a network. For example, the user can copy the files but not allowed to navigate through directories. Here, the access of the user is very limited. Instead, the username is set to anonymous and the password to the guest by default. So, the user can access those files without any username or password. Some sites can enable anonymous FTP whose files are available for public access. There are also built-in FTP programs, which makes it easier to transfer files and it does not require remembering the commands. Some of the commands are: get filename(retrieve the file from server), mget filename(retrieve multiple files from the server ), ls(lists files available in the current directory of the server). It is a set of commands that establishes the connection between two hosts, helps to transfer the files, and then closes the connection. The FTP client is a program that runs on the user’s computer to enable the user to talk to and get files from remote computers. FTP ClientsįTP works on a client-server model. The image file format is the default format for transforming binary files. In ASCII or EBCDIC the destination must be ready to accept files in this mode. The ASCII is the default file share format, in this, each character is encoded by NVT ASCII. FTP can transfer ASCII, EBCDIC, or image files. they differ in operating systems, directory, structures, character sets, etc the FTP shields the user from these differences and transfer data efficiently and reliably. Moreover, the systems involved in connection are heterogeneous systems, i.e. There are various other protocols like HTTP which are used to transfer files between computers, but they lack clarity and focus as compared to FTP. It promotes sharing of files and other types of data.įTP is a standard communication protocol.It shields users from system variations (operating system, directory structures, file structures, etc.).It encourages the direct use of remote computers.Role of Mahatma Gandhi in Freedom Struggle.
