Telnet. A terminal emulation protocol commonly used on Internet and TCP/IP-based networks. It allows a user at
a terminal or computer to log onto a remote device and run a program.
SMTP (Simple Mail Transfer Protocol). The standard e-mail protocol on the Internet. It is a TCP/IP protocol that
defines the message format and the message transfer agent (MTA), which stores and forwards the mail.
DNS (Domain Name System). The way that Internet domain names are located and translated into IP addresses.
A domain name is a meaningful and easy-to-remember “handle” for an Internet address.
TFTP (Trivial File Transfer Protocol). A version of the TCP/IP FTP protocol that has no directory or password
capability.
Finger. A UNIX command widely used on the Internet to find out information about a particular user, such as a
telephone number, whether the user is currently logged on, and the last time the user was logged on. The person
being “fingered” must have placed his or her profile on the system in order for the information to be available.
Fingering requires entering the full user@domain address.
HTTP (HyperText Transport Protocol). The communications protocol used to connect to servers on the World Wide
Web. Its primary function is to establish a connection with a web server and transmit HTML pages to the client
web browser.
POP3 (Post Office Protocol 3). A standard mail server commonly used on the Internet. It provides a message
store that holds incoming e-mail until users log on and download it. POP3 is a simple system with little
selectivity. All pending messages and attachments are downloaded at the same time. POP3 uses the SMTP
messaging protocol.
NNTP (Network News Transfer Protocol). The protocol used to connect to Usenet groups on the Internet. Usenet
newsreaders support the NNTP protocol.
