The use of a random sequence of frequency channels to
achieve spread spectrum compliance. Stations that use
frequency hopping change their communications frequency
at regular intervals. A hopping sequence determines the
pattern at which frequencies are changed. Messages take
place within a hop. See Hopping Sequence and Spread
Spectrum.
See File Transfer Protocol.
Flash memory is responsible for storing the system
firmware and is non-volatile. If the system power is
interrupted the data is not lost.
An IP address for a network gateway or router. A mobile
computer may be part of a subnet as specified by its IP
address and Netmask. It can send packets directly to any
node on the same subnet. If the destination node is on a
different subnet, then the mobile computer sends the
packet to the gateway first. The gateway determines how
to route the packet to the destination subnet. This field is
an option used by networks that require gateways.
See Cold Boot.
A set of random frequencies designed to minimize
interference with other sets of random frequencies. A
hopping sequence determines the pattern with which a
station that uses frequency hopping changes its
communications frequency. See Frequency Hopping.
Hertz; A unit of frequency equal to one cycle per second.
A computer that serves other mobile computers in a
network, providing such services as computation, database
access, supervisory programs and network control.
Intelligent drive electronics. Refers to the solid-state hard
drive type.
International Electrotechnical Commission. This
international agency regulates laser safety by specifying
various laser operation classes based on power output
during operation.
