Appendix C. Glossary
Authentication: The procedure to verify user identity as a security measure.
Passwords and digital signatures are the most popular forms.
DHCP: Dynamic Host Configuration Protocol. A method for automatically as-
signing IP addresses to computers on a local area network. With dynamic ad-
dressing, a device can have a different IP address each time it connects to the
network. Without DHCP, a network administrator would need to manually as-
sign and track static IP addresses for each device on the network. The official
specification is defined by RFC 2131.
Dialup: The procedure that activates an analog modem to connect to the ISP.
DNS: Domain Name System. An Internet service that maps alphabetic names
into IP addresses. For example, asante.com is a domain name that resolves to
the IP address 205.227.167.5.
FTP: File Transfer Protocol. Allows a user on one computer to transfer files to
and from another computer over a TCP/IP network. Requires software on both
the client and the server. A computer that runs FTP Server software and is used
to store files for downloading is called an FTP site or FTP server.
HTML: HyperText Markup Language – a text-based language used to build web
pages and interpreted by web browsers. Because the files are not restricted to a
single type of operating system, this allows websites to be platform-
independent; that is, to be viewed by computers regardless of their platform.
HTTP: HyperText Transmission Protocol. The protocol that computers use for
accessing web pages on the Internet.
Internet: A global network of interconnected computers and networks. Users
access the Internet via web browsers, e-mail, and other applications.
Intranet: A private network offering services similar to those offered by the
Worldwide public Internet, but for internal use by an organization.
IP Address: Internet Protocol Address. It is a unique number used to identify
computers in an IP network. The format of the IP address is 4 fields separated
by dots (for example: 192.168.132.250).
