IC

1. Short for Integrated Circuit or Integrated Chip, the IC was first introduced as a concept by Geoffrey Dummer a British radar engineer on May 7, 1952 and later successfully developed by Jack Kilby and Robert Noyce and first demonstrated September 12, 1958. The IC is a package containing many circuits, pathways, transistors, and other electronic components all working together to perform a particular function or a series of functions. Integrated circuits are the building blocks of computer hardware. To the right is an example of what an Integrated circuit may look like on a circuit board.
2. In role-playing games, IC is short for In-Character. IC is used to describe a player that is playing and acting out the role in the game and not talking about things not related to the game or the era of the game.
3. In chat rooms, IC is shorthand for I see. May also be abbreviated as OIC, which is short for Oh I See. Below is an example of how this could be used in chat.
