A communications channel has a bandwidth of 4,000 Hz and a signal-to-noise-ratio (SNR) of 30 dB. What is the maximum possible data rate?

In a CAN bus, there are three computers: Computer A, Computer B, and Computer C. The messages being sent are 2 milliseconds long. Computer A starts sending a message on the bus; 250 microseconds later, Computer B starts to send a message, and 250 microseconds after that, Computer C starts to send a message. When does Computer A retransmit its message?
