Application sharing
Application sharing is a feature that allows two people to
work together when one of the individuals doesn't have the same application, or
same version of the application. In application sharing, one user launches the
application and it runs simultaneously. Both users can input information and
otherwise control the application using the keyboard and mouse. Although it
appears that the application is running on both PCs, it actually is running on only
one, yet each user operates as though the application were running on both PCs.
Files associated with the application can be easily transferred, so the results of the
collaboration are available to both users immediately. The person who launched the
application can lock out the other person from making changes, so the locked-out
person sees the application running but cannot control it.
Band width
The throughput or ability to move information through or from a
device, system, or subsystem. Usually measured in quantities of data per second.
B channel
Bearer channel. The B channel is intended for transport of user
information, as opposed to signaling information.
BONDing
Bandwidth On Demand.
