network is assigned an address by a government agency, and each company
administrator assigns an address to each host computer.
MAC address
RF-MAC address is used for data services. This RF-MAC address is required to
provision Cable Modem for high-speed data services.
Modem registration
The process the Toshiba Cable Modem uses to make itself known to the headend
equipment. Once authorized by the router, the modem is assigned upstream and
downstream channels for data communication.
Network driver

divided into a subnet number and a host number. Hosts and gateways identify the bits
used for the network and subnet number through the use of a subnet mask.
TCP/IP communication stack
Software in the subscriber computer that processes packets through the
communication layers. The subscriber configures the IP address for the computer and
the router default gateway in the software. The TCP/IP communication stack handles
all the communications with the subscriber’s application.
USB
