Description
Hypertext Transfer Protocol (HTTP) is the protocol for transferring files on the World
Wide Web. HTTP is an application protocol that runs on top of the TCP/IP suite of
protocols, the foundation protocols for the Internet.
TELNET is the terminal emulation protocol of TCP/IP. TELNET uses TCP to achieve a
virtual connection between server and client, then negotiates options on both sides of
the connection.
File Transfer Protocol (FTP) is an application protocol that uses the Internet's TCP/IP
protocols. FTP provides a simple and efficient way to exchange files between
computers on the Internet.
Simple Mail Transfer Protocol (SMTP) is a TCP/IP protocol used for sending and
receiving email. Due to its limited ability to queue messages at the receiving end,
SMTP is often used with POP3 or IMAP. SMTP sends the email, and then POP3 or IMAP
receives the email.
Post Office Protocol (POP3) is a TCP/IP protocol intended to permit a workstation to
dynamically access a maildrop on a server host. A workstation uses POP3 to retrieve
email that the server is holding for it.
Domain Name Service (DNS) protocol searches for resources using a database that is
distributed among different name servers.

Transmission Control Protocol (TCP) is a set of rules used with Internet Protocol (IP) to send data as
message units over the Internet. While IP handles the actual delivery of data, TCP keeps track of
individual units of data called packets. Messages are divided into packets for efficient routing
through the Internet.
