Flash Memory : Flash memory is a non-volatile solid state storage device that is
packaged as a chip. It can be electrically erased and reprogrammed. It is
primarily used in memory cards, USB flash drives, MP3 players, and
solid-state drives for general storage and transfer of data between
computers and other digital products. It is a specific type of EEPROM
(electrically erasable programmable read-only memory) that is erased
and programmed in large blocks.
GPS : The Global Positioning System (GPS) is a space-based global navigation
satellite system (GNSS) that provides reliable location and time
information in all weather and at all times when and where an
unobstructed line of sight is available to four or more GPS satellites.
The system is maintained by the United States government and is
freely accessible by anyone with a GPS receiver. The Global Positioning
System is making it possible for people using ground receivers to
determine their geographic location within 10 meters to 100 meters.
The satellites use simple mathematical calculations to broadcast
information that is translated as longitude, latitude, and altitude by
Earth-based receivers.
Impedance : Impedance is a measure of RF component electrical resistance,
measured in ohms. In most cable and antenna systems, the standard
impedance is 50 ohms.
Insertion Loss : Insertion Loss (or Cable Loss) is a measure of the total amount of signal
energy absorbed (lost) by the cable assembly. It is measured in dB. S21
(an S-Parameter) is another name for this measurement.
IP Address : An Internet Protocol address (IP address) is usually a numerical label
that is assigned to each device (computer or printer for example) that is
participating in a computer network that uses the Internet Protocol for
communication. An IP address serves two main functions: location
addressing and host (or network) interface identification. The Internet
Protocol originally defined an IP address as a 32-bit number. This was
known as Internet Protocol Version 4 (IPv4), which is still in use.
Growth of the Internet requires a new addressing system. An Internet
Protocol Version 6 (IPv6) that uses 128 bits for the address was
developed in 1995, and it is standardized as RFC 2460. IPv6 began
being deployed worldwide in the year 2000. IP adresses are binary
