Electronic mail consists of messages sent through a computer network to

POP3 - port 110
IMAP - port 143
SMTP - port 25

FTP

File Transfer Protocol enables fast transfer of files, including large files that it

WWW

The World Wide Web is an Internet system to distribute graphical, hyper-

server protocol for the World Wide Web. The Web is not synonymous with the

Internet; rather, it is just one service on the Internet. Other services on the

Internet include Internet Relay Chat and Newsgroups. The Web is accessed

through use of a browser.
