   * **COB** - A DAQ board like the HSIO-II, but suited for more large-scale stuff.
-  * **DHCP** - [[https://technet.microsoft.com/en-us/library/dd145320(v=ws.10).aspx|Dynamic Host Configuration Protocol]]. Automatically assigns stuff like IP addresses to computers on a network.

You can find out what the settings in the file mean by reading [[http://linux.die.net/man/5/dhcpd.conf|this]], but you should know about things like IP addresses and private/public networks first.
