IC may refer to any of the following:
1. Alternatively referred to as a bare chip, monolithic integrated circuit, or microchip, IC is short for Integrated Circuit or Integrated Chip. The IC is a package containing many circuits, logic gates, pathways, transistors, and other components all working together to perform a particular function or a series of functions. Integrated circuits are the building blocks of computer hardware.
The picture shows an example of several integrated circuits. Because the IC is fragile, it's often encased in a plastic package with metal pins extending out of it to connect to a circuit board. An IC may be packaged as SIP (single in-line package), DIP (dual in-line package), PLCC (plastic leaded chip carrier), or another type.
When was the IC first created?
The integrated circuit was first introduced as a concept by British radar engineer Geoffrey Dummer on May 7, 1952. It was later developed by Jack Kilby and Robert Noyce, and successfully demonstrated on September 12, 1958.
Integrated circuit generations
Since their creation, there have been many different generations of integrated circuits with increases to the number of transistors and logic gates per chip. Below is a list of each of the generations and the approximate capacity of each chip.
- SSI (small-scale integration) - 1 to 10 transistors and 1 to 12 logic gates.
- MSI (medium-scale integration) - 10 to 500 transistors and 13 to 99 logic gates.
- LSI (large-scale integration) - 500 to 20,000 transistors and 100 to 9,999 logic gates.
- VLSI (very-large-scale integration) - 20,000 to 1,000,000 transistors and 10,000 to 99,999 logic gates.
- ULSI (ultra-large-scale integration) - over 1,000,000 transistors and 100,000 logic gates.
2. In role-playing games, IC is short for in character. IC is used to describe a player that is acting out their character's role in the game and not talking about things not related to 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.
