the LAN, individual workstations or computers can send messages and files to each other and to shared
devices, such as printers, disk storage, and other computer systems. LAN performance is measured in
the amount of data that can be transmitted and received, usually expressed as megabits transmitted per
second, so its critical factor is speed.

networks. The LNS architecture consists of the following elements:
1. The LNS Client application program, which can be used to develop, monitor and control
LonWorks networks.
2. The LNS Object Server ActiveX Control, which is a language-independent programming interface
to access the LonWorks network.
3. The Network Services Server (NSS), which maintains an image of the network.
4. The Data Server, which provides services for monitoring and control.
5. The Network Services Interface (NSI), which is the physical interface to the network.
LNS Event
An action handled by LNS that updates a LonMaker drawing. LNS events are used to track changes
made by an LNS application other than the LonMaker tool or a change in the status of device reported
by the LNS server. The LonMaker tool uses LNS events to keep it synchronized with other LNS
applications or plug-ins that are making changes to the network database.
LNS Network Database
Each L

network has its own LNS network database (also referred to as the network
database), which includes the network and device configuration data for that network. The network
database also contains extension records, which are user-defined records for storing application data.
LNS Server
The computer containing the LNS global database acts as the LNS Server. The LNS global database
contains the group of L
