PACKET

"Packet" refers to a small amount of something.  In the computer or wireless world, packet usually refers to "packet data".  Packet data means a portion of the data that someone might wish to send to another location.  Each "packet" would likely not only contain some of the data that is needed, but also a sending and a receiving address such that the system may understand where the information packet is to go.

If much data is to be transferred, the data will be broken down into "packets" - each containing a small portion of it.  At the receiving end, of course, this data is re-assembled to the complete data message that was intended.

The term "data" in the above might refer to voice, text, email, video or other data information.
