Short for Inter-Integrated Circuit, I2C (also known as I2C and IIC) is a technology developed by Philips. It's a bus interface connection protocol that facilitates communication between multiple devices utilizing a two-wire interface. More plainly, I2C is like a language that different components can use to talk to each other within an electronic system. For example, it can allow slower or older peripherals to connect to a computer motherboard and other embedded systems.

I2C is commonly used in electronics for connecting components like small displays, real-time clocks, sensors, EEPROM (electrically erasable programmable read-only memory), and other integrated circuits. Each piece of equipment on the bus has a unique address, and the primary device initiates communication by addressing a specific device. The two wire types involved in this process are SDA (Serial Data Line) and SCL (Serial Clock Line).
