a. The primary protocol used by Web servers and browsers (clients) is HTTP (Hypertext Transfer

b. In e-mail services, the recipient’s mail server delivers the message to the receiving client using
one of two protocols: POP3 (Post Office Protocol, version 3) or IMAP (Internet Message Access
Protocol, version 4). Using IMAP4, the email is downloaded to the client computer and typically
removed from the server. Using POP3 the client application manages the email while it remains
stored on the server.
c. FTP (File Transfer Protocol) is a client-server application that transfers files between two
computers, primarily using FTP. FTP uses encryption and is therefore extremely secure.

transmissions in Telnet are not encrypted. This has caused Telnet to be largely replaced by
other, more secure programs, such as the ssh command in the Linux operating system.
