Any more clarification then that Webopedia link in my above sentence?
It still doesn't make much sense to me (yet).
DOCSIS is like Ethernet, or Firewire, USB, ATA, SCSI, etc. It is a standard or specification that allows products from various manufacturers to work together and accomplish a task. In this case, giving you Internet access over the cable network. If DOCSIS was not around or the equivalent, then the cable company would have to buy the backend equipment from the same provider as the cable modems and would be locked into that specific vendor for everything. DOCSIS allows the manufacturers to test their equipment and verify that it follows DOCSIS and they consumers and cable companies will be able to use it and it will work.
To put it into another perspective, imagine if Ethernet didn't exist and you needed to move files from one computer to another. Both computers have a NIC, but there are from two different manufacturers. The first computer has a NIC from brand A and it only works with switches and router from brand A. The other computer has one from brand Z and it only works with other products from brand Z.
