Computing Dictionary
on-line definition
jargon 1. Ready for use. E.g. "The graph plotter's fixed and on-line again".
2.
Interactive as opposed to
batch. Accessible via a computer (or
terminal), rather than on paper or other medium.
3. Of a user, actively using a computer system, especially the
Internet. E.g "I haven't been on-line for three days."
"On-line" should be hyphenated because it is compounded from two words but the hyphen is often omitted in names of organisations or services.
