In the sentence below
The processor puts the data it wants to write on a bank of electrical traces, the data bus, by raising the voltage on some to represent ones and leaving voltages unchanged on others to represent zeros.
What is the relationship between 'a bank of electrical traces' and 'the data bus'? Does the sentence mean the processor put both on 'a bank of electrical traces' **and '**the data bus'?
Thank you in advance.
