SDA and SCL are connected to a voltage source via pull-up resistors, allowing devices to pull the lines low without creating short circuits.

Multiple masters can control the same slave, and multiple slaves can reside on the same bus.

The master sends the 7-bit unique address of the target slave, followed by a R/W bit (0 for write, 1 for read).
