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:
“It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.”
—François, Duc De La Rochefoucauld (1613–1680)
“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)
“One definition of man is “an intelligence served by organs.””
—Ralph Waldo Emerson (1803–1882)
