Handoff: The transfer of a cellular phone transmission from one radio frequency within a cell to another radio frequency in an adjacent cell. Handoffs occur when a cellular phone user passes out of the range that the cell can handle and into another cell’s range, and the signal is passed from one base station to the next. The handoff is transparent to the user and typically will not result in a loss of service unless the user moves out of range of a cell’s base station. The transition and the process required to make the transition are both referred to as the handoff. Scalable parallel processor: Abbreviated as SPP, a computer that utilises parallel processing that can be upgraded by adding more CPUs to it, effectively increasing its computing power. PVR: Short for
personal video recorder, a generic term for a device that is similar to
a VCR but records television data in digital format as opposed to the
VCR’s analog format. VCRs utilise analog tapes to record and play
programs broadcast over television, but PVRs encode video data in MPEG-1
or MPEG-2 formats and store the data in a hard drive. PVRs have all of
the same functionality of VCRs (recording, playback, fast forwarding,
rewinding, pausing) plus the ability to instantly jump to any part of
the program without having to rewind or fast forward the data stream. Password: A secret
series of characters that enables a user to access a file, computer, or
program. On multi-user systems, each user must enter his or her password
before the computer will respond to commands. The password helps ensure
that unauthorized users do not access the computer. In addition, data
files and programs may require a password.
