Frame relay
A high-speed packet-switching protocol used in wide area networks (WANs). Frame
Relay provides for a granular service up to DS1 rates of 1.544 Mbps and is suited for
data and image transfer.
Frequency
The number of times that an alternating current goes through its complete cycle in one
second of time. One cycle per second is also referred to as “one hertz; 1000 cycles per
second, one kilohertz; 1,000,000 cycles per” second, one megahertz, and
1,000,000,000 cycles per second one gigahertz.
Gateway
A computer that performs protocol conversion between different types of networks or
applications.
Hardware
Machinery and equipment (CPU, disks, tapes, modem, cables, etc.).
IANA
Internet Assigned Numbers Authority: central coordinator for the assignment of unique
parameter values for Internet protocols.
IEC
International Electrotechnical Commission: an organization that sets international
electrical and electronics standards founded in 1906 and headquartered in Geneva.
IGMP
Internet Group Management Protocol: protocol used by the IP host to report its
multicast group memberships to an adjacent multicast router (see RFC 2236).
Init string
Initialization String: a character string made up of control codes and commands that is
sent to a printer of modem for setup and initialization.
IP
An identifier for a computer or device on a TCP/IP network. Networks using the TCP/
IP protocol route messages based on the IP address of the destination. The format of an
IP address is a 32-bit numeric address written as four numbers separated by periods.
Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.
Within an isolated network, you can assign IP addresses at random as long as each one
is unique. However, connecting a private network to the Internet requires using
registered IP addresses (called Internet addresses) to avoid duplicates (see RFC 791).
IRD
Integrated Receiver Decoder. Set-top box used for the reception and descrambling of
signals. In the case of digital reception, the decoder is integrated with the satellite
receiver.
ISDN
Integrated Services Digital Network: an international telecommunications standard for
transmission over digital lines running at 64 kbps. ISDN uses 64-kbps circuit-switched
channels, called B channels, or bearer channels, and a separate D channel, or delta,
