I2C is an acronym for Inter-Integrated-Circuit-Communications. It was invented by Phillips Semiconductor, now NXP. It's meant to provide simple, robust, inexpensive and easy-to-use communications between a "chain" of devices. Many devices such as accelerometers, temperature sensors, pressure sensors, etc. communicate on the I2C bus.
