an installed DOS code page that contains the standard ASCII character set and a set of

downline
A device that is at the terminal end of a connection to the computer is referred to as being

If more than one computer is connected in a line, the upline computers usually handle
data processing and the downline computers usually handle data collection and sometimes
data “preprocessing.”
