Hi every body.
i have cable internet. I get my television channels and internet from the same cable. I understand how the bandwidth of cable is allocated to to each television channel, internet access. I am just wondering what is the access method used by hosts to access internet. For example on ethernet, csma is used. thanks and have a nice weekend.
Hi,
A Cable modem is a device used to connect a computer to a cable TV service for Internet access, A cable modem modulates and demodulates signals like a telephone modem but is a much more complex device. Data can be transferred over cable lines much more quickly than over traditional phone lines. Transmission rates range from about 8 megabits per second (Mbps) for basic services to some 50 Mbps for premium services
Cable modems connect to the computer via an Ethernet port, which is an always-on connection. Ethernet is a shared medium, and the individual user's speed will vary depending on how many customers are sending or receiving data on that cable segment at the same time
Internet packets are combined with standard TV programming in a cable modem system. The cable modem termination system (CMTS) is responsible for packet to RF conversion, routing, bridging, filtering and traffic shaping (see CMTS).
Hope to Help !!
