B. Local Interconnect Network (LIN): LIN is an asynchronous serial broadcast bus where all messages are initiated by the one single master with at most one slave replying to a given message identifier. The  Local Interconnect Network (LIN) bus was developed to create a standard for low-cost, low-end multiplexed communication in automotive networks. LIN provides cost-efficient communication in applications where the bandwidth and versatility of CAN are not required.
 
 LIN is a single wire communication bus with data rates up to 20 Kbps which is suitable for modules where response time is not a critical issue as mirror controls and window controls. The LIN bus is a polled bus with a single master device and one or more slave devices. The master device contains both a master task and a slave task. Each slave device contains only a slave task.
