Glossary
Access Point - A device that is able to receive wireless signals and transmit them to the wired network, and vice versa -
thereby creating a connection between the wireless and wired networks.
Adapter - A device used to connect end-user nodes to the network; each contains an interface to a specific type of
computer or system bus, e.g. EISA, ISA, PCI, PCMCIA, CardBus, etc.
Auto-Negotiation - A signaling method that allows each node to define its operational mode (e.g., 10/100 Mbps and
half/full duplex) and to detect the operational mode of the adjacent node.
Backbone - The core infrastructure of a network. The portion of the network that transports information from one central
location to another central location where it is unloaded onto a local system.
Base Station - In mobile telecommunications, a base station is the central radio transmitter/receiver that maintains
communications with the mobile radiotelephone sets within its range. In cellular and personal communications
applications, each cell or micro-cell has its own base station; each base station in turn is interconnected with other cells'
bases.
BSS - BSS stands for "Basic Service Set". It is an Access Point and all the LAN PCs that are associated with it.
CSMA/CA - Carrier Sense Multiple Access with Collision Avoidance
DHCP - Dynamic Host Configuration Protocol. This protocol automatically configures the TCP/IP settings of every
computer on your home network.
DNS - DNS stands for Domain Name System, which allows Internet host computers to have a domain name (such as
www.smc.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of host computers
and their respective domain names and IP addresses, so that when a domain name is requested (as in typing "
www.smc.com" into your Internet browser), the user is sent to the proper IP address. The DNS server address used by the
computers on your home network is the location of the DNS server your ISP has assigned.
DSL - DSL stands for Digital Subscriber Line. A DSL modem uses your existing phone lines to transmit data at high
speeds.
Ethernet - A standard for computer networks. Ethernet networks are connected by special cables and hubs, and move data
around at up to 10 million bits per second (Mbps).
ESS - ESS (ESS-ID, SSID) stands for "Extended Service Set". More than one BSS is configured to become an Extended
Service Set. LAN mobile users can roam between different BSSs in an ESS (ESS-ID, SSID).
Fast Ethernet NIC - Network interface card that is in compliance with the IEEE 802.3u standard. This card functions at the
media access control (MAC) layer, using carrier sense multiple access with collision detection (CSMA/CD).
