Just a fundamental LAN network questions as I am studying CCNA course<br />
<br />
Computer A and B both are connected to a normal L2 switch and turned on. there is no DNS server configured (it shouldn't matter as it is pure L2 connection?)<br />
what are the setups computer A pinging computer B by the name at the very first time? is the switch going to broadcast computerB's mac address? if yes, how would computer A know what is the computer B's mac? &nbsp;<br />
just trying to understand the principle of LAN communication. <br />
It would be great if I can get some articles to read.<br />
<br />
Thanks

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
