OSI reference model A seven layer scheme describing the various functions required for network and
computer communications. OSI stands for Open Systems Interconnection, which is the
International Standards Organization’s (ISO) program for standardization of data
communications.
PCMCIA The Personal Computer Memory Card International Association (PCMCIA) is a
standards organization that has developed standards for a PC card that fulfills the same
function as the AT bus on standard desktop computers—it provides universal,
non-proprietary expansion capability.
peer-to-peer network A network consisting only of workstations and peripheral devices, with no centralized,
dedicated server. An example of peer-to-peer network operating system is Microsoft
Windows 95. In BayStack 600 Wireless LAN networks, if a peer-to-peer network does not
include access to a wired network through a BayStack access point it is called an ad hoc
or standalone network.
See Ad hoc network and server-based network.
Physical layer The lowest level of the OSI reference model for data communications. It includes
transmission media such as cabling or, in the case of BayStack 600 Wireless LAN
products, radio waves. BayStack 600 Wireless LAN technology has been designed to
provide a level of reliability at the physical level comparable to that of wired LAN
adapters.
QuickList One of up to 10 groups of access points that you can quickly access using the Configure
and Actions menu in AP manager.
Resource manager See Configuration utility.
Roam Now A function button which permits the user to force the mobile unit to roam and select the
BayStack access point that provides the best performance at this time.
roaming A feature of a BayStack 660 Wireless LAN network that allows the user to move about
freely within range of the other workstations or BayStack access points on the network
without losing connection to the network. In a network with multiple access points, for
example, a roaming user can move out of range of one BayStack access point and into
the range of another BayStack access point without being disconnected.
server-based network A local area network on which network processing and storage are located on a
dedicated workstation or server to which other devices on the network are connected. A
server-based BayStack 600 Wireless LAN network, by definition, must include at least
one BayStack 660 Access Point giving workstations access to the wired network on
which the server is located. A BayStack 600 Wireless LAN network that does not include
an access point is called an ad hoc network.
See also peer-to-peer network and ad hoc
network.
service area The coverage around a BayStack 660 Access Point that is used by a mobile unit to
connect to a wired network. Users can roam from one service area to another without
losing connection to the network.
SNMP Simple Network Management Protocol.
Socket services A PCMCIA BIOS-level interface that hides the hardware implementation from the PC
vendor’s driver software. It identifies the number of PCMCIA sockets in the computer and
detects when a card is inserted into or removed from a socket.
