G-40 Glossary
service A program or process that runs in the background on a computer to perform
particular system functions for other programs.
service access point (SAP) The interface between each of the seven layers in the
OSI protocol stack that has connection points, similar to addresses, used for communication
between layers. Any protocol layer can have multiple SAPs active at
one time.
Service Advertising Protocol (SAP) Allows service-providing nodes (including file,
printer, gateway, and application servers) to advertise their services and addresses.
service dependency The other services that must be running for a service to start, as
well as the services that cannot start until the service in question starts.
Service Pack A software upgrade to an existing software distribution that contains
updated files consisting of patches and fixes.
session A connection or link between stations on a network.
session layer The fifth layer of the OSI reference model. This layer allows two applications
on different computers to establish, use, and end a connection called a
session. This layer performs name recognition and functions, such as security,
needed to allow two applications to communicate over the network. The session
layer provides synchronization between user tasks. This layer also implements
dialog control between communicating processes, regulating which side transmits,
when, for how long, and so on. See also Open Systems Interconnection (OSI) reference
model.
session management Establishing, maintaining, and terminating connections
between stations on the network.
shared folder A folder made accessible to users on the network.
shared folder permissions Permissions assigned to shared folders that control
access to the folder over the network. Shared folder permissions include Read,
Change, and Full Control.
sharing Means by which files of folders are publicly posted on a network for access
by anyone on the network.
shell A piece of software, usually a separate program, that provides direct communication
between the user and the operating system. This usually, but not always,
takes the form of a command-line interface. Examples of shells are Macintosh
Finder and the MS-DOS command interface program COMMAND.COM.
SID See Security Identifier (SID).
Simple File Sharing A type of sharing that is used when a Windows XP computer
has not joined a domain or is running Windows XP Home Edition.
