Internet (Upper case I) The vast collection of inter-connected networks that all use the TCP/IP
protocols and that evolved from the ARPANET of the late 60’s and early 70’s.
Intranet A private network inside a company or organization that uses the same kinds of
software that you would find on the public Internet, but that is only for internal use.
IP Internet Protocol. The IP (currently IP version 4, or IPv4), is the underlying protocol for
routing packets on the Internet and other TCP/IP-based networks.
IP Alias Internet Protocol Alias allows you to partition a physical network into different logical
networks over the same Ethernet interface. The Prestige supports three logical LAN
interfaces via its single physical Ethernet interface with the Prestige itself as the
gateway for each LAN network.
IP Pool Internet Protocol Pool refers to the collective group of IP addresses located in any
particular place (for example, LAN, WAN, Ethernet, etc.).
IP Routing Policy Traditionally, routing is based on the destination address only and the router takes the
shortest path to forward a packet. IP Routing Policy (IPRP) provides a mechanism to
override the default routing behavior and forward the packet based on the policy
defined by the network administrator.
IPCP (PPP) IP Control Protocol allows changes to IP parameters such as the IP address.
IPX Internetwork Packet eXchange. Like IP (Internet Protocol), IPX is an internetworking
protocol that provides datagram services. The native NetWare internetworking protocol
is IPX (Internetwork Packet Exchange).
IRC Internet Relay Chat. IRC was developed in the late 1980s as a way for multiple users
on a system to “chat” over the network. Today IRC is a very popular way to “talk” in
real time with other people on the Internet. However, IRC is also one avenue hackers
use to obtain information about your system and/or company. Moreover, IRC sessions
are prone to numerous attacks that, while not dangerous, can cause system crashes.
ISP Internet Service Providers provide connections into the Internet for home users and
businesses. There are local, regional, national and global ISPs. You can think of local
ISPs as the gatekeepers into the Internet.
Jack Type Different types of jacks (RJ11, RJ45 or RJ48) can be used for an ISDN line. The RJ11
is the most common in the world and is most often used for analog phones, modems
and fax machines. RJ48 and RJ45 are essentially the same, as they both have the
same 8-pin configuration. An RJ11 jack can fit into an RJ45/RJ48 connector, however,
an RJ45/RJ48 cannot fit into an RJ11 connector.
LAN Local Area Network is a shared communication system to which many computers are
attached. A LAN, as its name implies, is limited to a local area. This has to do more
with the electrical characteristics of the medium than the fact that many early LANs
