I²C is a serial computer bus invented by Philips. It is used by small low-speed peripherals to communicate with a processor.
My last project used I²C. I had a couple of video processing integrated circuits, and an A-to-D converter that used I²C. The Master I²C communicator would send out commands to these devices, and they would listen to their address, then act on the commands given to them (and reply, when requested).
Since it is a serial bus, and a multi-master bus (everyone is connected to 3 lines: data, clock, and reset), it cuts down on the number of traces taken up by communications
A loose comparison to I²C would be USB.

I2C bus is an interface bus invented by Philips. It uses two wired signals ( SDA and SCL ) to communicate in both directions, between the master and the slave.
It's also used in all PCs, but known as the "SM bus".
