What does it mean to send serially information in I2C?

[brunokasimin]

'I2C' stands for Inter-Integrated Circuit and allows communication of data between I2C devices over two wires. It sends information serially using one line for data (SDA) and one for clock (SCL).

Can anyone explain me what means by the term 'serially'?

i2c

Just means its sends one bit after the other over a single line.
As opposed to sending several bits simultaneously over more than one line.

Re: i2c

On a I2C interface, the data you are sending down the wire is either a logic "1" or a logic "0". The data will change between these 2 values. So typically, you set the data line high or Low then you set the clock line from low to high to low. And keep repeating till all the data is transmitted.
