what is a pda in an aircraft
If you asked what a file on a PDA is, my answer is everything. anything you see on a desktop computer can also be a file on a PDA. If you asked what a .pda file (having an extension of PDA), sorry, no idea. :)
PDA's can be connected to a computer. Files can be transferred from the PDA to the computer and from the computer to the PDA. Data such as phone numbers, addresses and appointments can be synchronized between PDA's and computers so the information can be the updated.

FUTURE TRENDS OF PDA

Depends on the PDA.
the disadvantages of the PDA are that they are very large.
It is an opinion. General etiquette states that it depends on how much PDA, a little pda is ok, very graphic pda or extreme mush not so much. Also, where the display is, in a theatre, depends on how loud, at a club the rules are less stringent.
