I2C - Inter Integrated-circuit Communication. A two-wire (data + clock) bus used for low-speed (up to 400 kbit/s) communications between microcontrollers and other chips like other micros, sensors, eeproms, etc. Developed and standardised by Philips.

I2S - Inter Integrated-circuit Sound. Used for synchronous (clocked) serial communication of audio data between ADCs, DSPs, and DACs. This is not a bus, it is point-to-point, and it uses two clocks (bit clock and left/right or LR clock). There are several slightly different and very incompatible 'standards', which can make it tricky to just connect stuff together and expect it to talk.
