What is a protocol and why is it important in electronic communications? * Protocol: Rules that govern data communication, including error detection, message length, and transmission speed * Because before a communication link can be established between 2 devices, they must be synchronized, meaning that both devices must start and stop communication at the same point.

You can use the ipconfig command to get host computer configuration information, including the IP address, mac address, your adapter info and router or switch info, subnet mask, and default gateway. the tracert command can be used to check the path to the destination IP address that you want to reach. The tracert command displays the series of IP routers that are used in delivering packets from your computer to the destination and how long it took on each hop. If the packets are unable to be delivered to the destination, the tracert command displays the last router that successfully forwarded your packets. To get more detailed information about throughput rates and to determine what the physical topology is you need to be able to access the equipment and telco rooms because there might be some hidden problems.
