For All Installations
Router
Device that routs IP (usually Ethernet) transmissions. In most home or small
business situations, the router performs two related tasks. First, it provides the
homeowner’s LAN, managing communication between all the devices on that
network. Second, the router communicates with the modem and through it with
the Internet. The place where two or more networks connect is called a gateway.
A router is located at a gateway and by communicating with the other devices on
the networks determines the best path for forwarding the data packets.
Server
A server is a computer or device on a network that stores and manages the
network’s resources. There are several different types or functions of servers.
For example:
A file server is a computer and storage device dedicated to storing files.
Users on the network can store and retrieve files on the server.
A print server is a computer that manages one or more printers. A
network server is a computer that manages network traffic.
A database server is a computer system that processes database queries.
Internet servers
store and serve the specially formatted documents
viewed by web browsers; the addresses for these documents include the
IP address of the server.
LoBenn Network Server
stores the monitoring information for a
number of individual LNIs. When an LNI signals an alarm or
communication failure, the LNS relays that information to the
monitoring center.
Switch
Device that routs IP (usually Ethernet) transmissions.
In networks, the switch filters and forwards packets between devices on a LAN.
Unlike a router, a switch does not communicate with other networks; it simply
provides more physical connections (ports) to the LAN.
Subnet
A subnet is the portion of a network sharing a common address component. On
TCP/IP networks, subnets consist of all the devices in the network whose IP
addresses have the same prefix. Subnets are used to improve both the security
and performance of a network. IP networks are divided using a subnet mask.
