The correct answer is: D. FTP
FTP stands for File Transfer Protocol. It is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is a client-server protocol, which means that there are two computers involved in the transfer: a client and a server. The client is the computer that initiates the transfer, and the server is the computer that hosts the files to be transferred.
FTP uses two connections between the client and the server: a control connection and a data connection. The control connection is used to control the transfer, such as to initiate the transfer, to list the files on the server, and to download or upload files. The data connection is used to transfer the actual files.
FTP is a very simple protocol, and it is supported by most operating systems and web browsers. It is a very common way to transfer files over the internet.
The other options
are:- TCP: Transmission Control Protocol. TCP is a connection-oriented protocol, which means that it establishes a connection between the client and the server before any data is transferred. This ensures that the data is transferred reliably.
- HTTP: Hypertext Transfer Protocol. HTTP is a protocol used for the transfer of hypertext documents, such as web pages. It is a stateless protocol, which means that it does not maintain any state between requests.
- SMTP: Simple Mail Transfer Protocol. SMTP is a protocol used for the transfer of email messages. It is a text-based protocol, and it is used to send email messages from a client to a server.
