Definition
Instant messaging falls under the umbrella term online chat, since it is also text-based, bi-directionally exchanged, and happens in real-time. IM is distinct from chat in that IM is based on clients that facilitate connections between specified known users (often using a contact list, buddy list, or friend list). Online 'chat' includes web-based applications that allow communication between (often directly addressed, but anonymous) users in a multi-user environment.

Famous quotes containing the word definition:
“Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.”
—The Columbia Encyclopedia, Fifth Edition, the first sentence of the article on “life” (based on wording in the First Edition, 1935)
“No man, not even a doctor, ever gives any other definition of what a nurse should be than this—”devoted and obedient.” This definition would do just as well for a porter. It might even do for a horse. It would not do for a policeman.”
—Florence Nightingale (1820–1910)
“Was man made stupid to see his own stupidity?
Is God by definition indifferent, beyond us all?
Is the eternal truth man’s fighting soul
Wherein the Beast ravens in its own avidity?”
—Richard Eberhart (b. 1904)
