Glossary 81
short name An abbreviated name for a user. The short name is used by Mac OS X for
home directories, authentication, and email addresses.
Simplified Finder A user environment featuring panels and large icons that provide
novice users with an easy-to-navigate interface. Mounted volumes or media to which
users are allowed access appear on panels instead of on the standard desktop.
SMB/CIFS Server Message Block/Common Internet File System. A protocol that allows
client computers to access files and network services. It can be used over TCP/IP, the
Internet, and other network protocols. Windows services use SMB/CIFS to provide
access to servers, printers, and other network resources.
SMTP Simple Mail Transfer Protocol. A protocol used to send and transfer mail.
Its ability to queue incoming messages is limited, so SMTP usually is used only to send
mail, and POP or IMAP is used to receive mail.
SNMP Simple Network Management Protocol. A set of standard protocols used to
manage and monitor multiplatform computer network devices.
spam Unsolicited email; junk mail.
SSL Secure Sockets Layer. An Internet protocol that allows you to send encrypted,
authenticated information across the Internet. More recent versions of SSL are known
as TLS (Transport Level Security).
static IP address An IP address that’s assigned to a computer or device once and is
never changed.
subnet A grouping on the same network of client computers that are organized by
location (different floors of a building, for example) or by usage (all eighth-grade
students, for example). The use of subnets simplifies administration. See also IP subnet.
system-less client A computer that doesn’t have an operating system installed on its
local hard disk. System-less computers can start up from a disk image on a NetBoot
server.
TCP Transmission Control Protocol. A method used along with the Internet Protocol
(IP) to send data in the form of message units between computers over the Internet.
IP takes care of handling the actual delivery of the data, and TCP takes care of keeping
track of the individual units of data (called packets) into which a message is divided for
efficient routing through the Internet.
Tomcat The official reference implementation for Java Servlet 2.2 and JavaServer Pages
1.1, two complementary technologies developed under the Java Community Process.
UID User ID. A number that uniquely identifies a user within a file system. Mac OS X
computers use the UID to keep track of a user’s directory and file ownership.
