Chapter 8 Data Communications
access point - ANS-The interconnecting bridge between a wireless local area network
workstation and the wired local area network
Active Directory - ANS-Network directory structure for Windows Server OS, a hierarchical
structure that stores information about all the objects and resources in a network and makes this
information available to users, network administrators, and application programs.
anti-spam software - ANS-software designed to detect and block spam that has been sent to a
computer
antivirus software - ANS-software designed to detect and remove viruses that have infected a
computer's memory, disks, or OS.
application programming interface (API) - ANS-a software module that acts as an interface
between application programs and technical entities, such as telephone switching systems.
backup software - ANS-software that allows network administrators to backup the data files
currently stored on the network server's hard disk drive.
Basic Service Set (BSS) - ANS-the transmission area surrounding a single access point in a
wireless local area network; it resembles a cell in a cellular telephone network.
bindery - ANS-a database that contains information on every resource connected to this one
server, including users, groups of users, printers, and data sets.
carrier sense multiple access with collision avoidance (CSMA/CA) - ANS-a contention-based
medium access control protocol for wireless networks in which wireless workstations can only
transmit at designated times, in an attempt to avoid collisions
corporate license - ANS-an agreement that allows a software package to be installed anywhere
within a corporation, even if the installation involves multiple sites.
crash protection software - ANS-software whose primary goal is to perform crash stalling (to try
to keep the OS running long enough to perform a graceful exit) on a workstation or network of
workstations.
disk mirroring - ANS-a technique used in RAID systems in which data is duplicated onto two
drives simultaneously in order to provide a backup for the data.
, domain - ANS-the primary unit of administration in all of the Windows network operating
systems.
Extended Service Set (ESS) - ANS-In a wireless LAN topology, the collection of all the Basic
Service Sets attached to the local area network through its access points.
General Public License (GPL) - ANS-a software license that allows the creator to distribute the
software for free; recipients may alter the software as they wish, but must still give the altered
software away for free.
hidden workstation - ANS-a situation when two wireless devices can communicate to an access
point but cannot see each other (the tow devices cannot intercommunicate by themselves)
interactive user license - ANS-an agreement in which the number of concurrent active users of a
particular software package is strictly controlled.
interframe space (IFS) - ANS-the time in which a workstation waits before transmitting on a
wireless local area network.
Internet software - ANS-the tool set of network software to support Internet-related services that
include Web browsers, server software, and Web page publishing software, among other
applications.
leaf objects - ANS-an object in a hierarchical directory structure that is composed of no further
objects and includes entities such as users, peripherals, servers, printers, queues, and other
network resources.
licensing agreement - ANS-a legal contract that describes a number of conditions that must be
upheld for proper use of the software package.
media converters - ANS-devices that convert cables and/or signals from one form to another
multiple input multiple output (MIMO) - ANS-a technology used in wireless LANs in which
sending and receiving devices have multiple antennas and transmit data over multiple streams
in an effort to send data faster with fewer errors.
multitasking operating system - ANS-an operating system that schedules each task and
allocates a small amount of time to the execution of each task
NetWare Directory Services (NDS) - ANS-Now called eDirectory, a database that maintains
information on, and access to, every resource on the network, including users, groups of users,
printers, data sets, and servers.
