ISDN Line
IEEE-1394 (Initially known as "Firewire")
- Interface specifications targeted for desktop and
laptop computers. Defines a cross-platform implementation of the
high-speed serial data bus that can move large amounts of data between
computers and peripheral devices. It features simplified cabling, hot
swapping, and transfer speeds of up to 400 megabits per second..
Firewire speeds up the movement of multimedia data and large files and
enables the connection of digital consumer products - including digital
camcorders, digital video tapes, digital video disks, set-top boxes, and
music systems (
Intranet:
A private network inside an organization that uses
the same kinds of software found on the public Internet, usually used
only for internal use. As the Internet has become more popular many of
the tools used on the Internet are being used in private networks, for
example, many companies have web servers that are available only to
employees. Note that an Intranet may not actually be an Internet, it may
simply be a network.
IP (Internet Protocol) --
Internet Protocol handles the address
part of each data packet that is transmitted from one computer to
another on the Internet. (A protocol is the set of rules computers use
to talk to each other.) Each computer (or host) on the Internet has a
unique address containing four numbers separated by periods (for
example, 199.0.0.2). Each file you request (for example, someone's Web
home page) is identified in part by a domain name that maps to the
Internet address of its computer. The file you request is in turn sent
to you at your associated Internet address by the IPs at either end of
the exchange.
The Internet Protocol, together with the
Transmission Control Protocol (TCP), which manages the assembly and
reassembly of data into the information packets sent over the Internet,
form a program, TCP/IP, that each computer on the Internet uses to
communicate with any other computer.
IPX (Internetwork Packet
Exchange) -- A networking protocol from
Novell that interconnects networks that use Novell's NetWare clients and
servers. IPX is a datagram or packet protocol. IPX works at the network
layer of communication protocols and is connectionless (that is, it
doesn't require that a connection be set up before packets are sent to a
destination as, for example, a regular voice phone call does).
Packet acknowledgment is managed by another
Novell protocol, the Sequenced Packet Exchange™ (SPX). Other related
Novell NetWare protocols are: the Routing Information Protocol (RIP),
the Service Advertising Protocol (SAP), and the NetWare Link Services
Protocol (NLSP).
ISDN (Integrated Services
Digital Network) -- Basically a way to
move more data over existing regular phone lines. Precursor to xDSL
technologies. Can provide speeds of roughly 128Kbps over regular phone
lines. In practice, most people will be limited to one or two 56Kbps
channels allowing the option for two channels of either voice or data.
Typical end user ISDN uses 2B+D channels. See:
