Dynamic Routing
Dynamic routing uses a routing protocol to exchange routing information with
neighboring routers on the network. It calculates routing tables based on a given
metric, such as lest number of hops or shortest path. It can respond to changes in
the status or traffic on the network, re-routing traffic as required.
End Station
A workstation, server, or other device that does not forward traffic.
Ethernet
A network communication system developed and standardized by DEC, Intel, and
Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and
coaxial cable. The successor IEEE 802.3 standard provides for integration into the
OSI model and extends the physical layer and media with repeaters and
implementations that operate on fiber, thin coax and twisted-pair cable.
Fast Ethernet
A 100 Mbps network communication system based on Ethernet and the CSMA/CD
access method.
Firewall
A firewall is designed to prevent unauthorized access to or from a private network
Full Duplex
Transmission method that allows two network devices to transmit and receive
concurrently, effectively doubling the bandwidth of that link.
Hosting Server
A network device that may provide a limited number of services for external IP
clients, but is also used to transparently redirect specific service requests (such as
web or FTP) to other dedicated local servers.
Internet Group Management Protocol (IGMP)
A protocol through which hosts can register with their local router for multicast
services. If there is more than one multicast switch/router on a given subnetwork,
one of the devices is made the “querier” and assumes responsibility for keeping
track of group membership.
Internet Service Provider (ISP)
A company that provides access to the Internet. This may be your local telephone
company, or a dedicated Internet service company.
