78 Glossary

IP Internet Protocol. Also known as IPv4. A method used with Transmission Control

Protocol (TCP) to send data between computers over a local network or the Internet. IP

delivers packets of data, while TCP keeps track of data packets.

IP address A unique numeric address that identifies a computer on the Internet.

Jboss A full-featured Java application server that provides support for Java 2 Platform,

Enterprise Edition (J2EE) applications.

Kerberos realm The authentication domain comprising the users and services that are

registered with the same Kerberos server. The registered services and users trust the

Kerberos server to verify each other’s identities.

local hostname A name that designates a computer on a local subnet. It can be used

without a global DNS system to resolve names to IP addresses. It consists of lowercase

letters, numbers, or hyphens (except as the last characters), and ends with “.local” (e.g,

bills-computer.local). Although the name is derived by default from the computer

name, a user can specify this name in the Network pane of System Preferences. It can

be changed easily, and can be used anywhere a DNS name or fully qualified domain

name is used. It can only resolve on the same subnet as the computer using it.

multicast DNS A protocol developed by Apple for automatic discovery of computers,

devices, and services on IP networks. This proposed Internet standard protocol is

sometimes referred to as “ZeroConf.” For more information, visit www.apple.com or

www.zeroconf.org. To see how this protocol is used in Mac OS X Server, see local

hostname.

MySQL An open source relational database management tool frequently used by web

servers.

open source A term for the cooperative development of software by the Internet

community. The basic principle is to involve as many people as possible in writing and

debugging code by publishing the source code and encouraging the formation of a

large community of developers who will submit modifications and enhancements.

PHP PHP Hypertext Preprocessor (originally Personal Home Page). A scripting

language embedded in HTML that’s used to create dynamic webpages.

port A sort of virtual mail slot. A server uses port numbers to determine which

application should receive data packets. Firewalls use port numbers to determine

whether data packets are allowed to traverse a local network. “Port” usually refers to

either a TCP or UDP port.

protocol A set of rules that determines how data is sent back and forth between two

applications.
