Cable Modem Access

             The Internet has been around for over 40 years and despite technological advances in speed, people still complain that it's too slow. How can people get their favorite songs or visit their favorite sites before dinner is over? This paper will discuss one option, cable internet access.
             Until now internet the public had to access the WWW through slow phone lines, connecting anywhere from 300 bps in the infancy of public access to 56k. But now there are several high-speed alternatives to the old phone line, one being the cable modem. Using your cable TV provider as your ISP, people can access the Internet at speeds up to 27 Mbps, but limitations with hardware limit this to about 2Mbps (www.TechTarget.com). This speed is fine for most users. It is also "always on". Meaning you do not have to dial-up to your ISP. It is similar to a LAN connection. This hasn't been done before mainly because when cable TV companies were being formed, the networks were only being set up to send data and not to receive it. The remedy for this was to upgrade the networks not only to be able to receive information, but to handle the larger amount of bandwidth (www.Vicomsoft.com). .
             The way cable internet access is possible is my using a standard cable TV coax line as the medium and a cable modem to connect the computer to the Internet. The cable TV provider has a Cable Modem Termination System (CMTS) that then goes through the coax line to the home. The coax line is then connected to a splitter, with one line going to the television or set-top box, and the other to the cable modem (www.Techtarget.com). The cable modem then is connected to a PC via a Cat 3 or 5 cable to a network card. Some modems can also be connected via the USB or FireWire port. .
             The type of modem a person needs depends on the standard the provider is using. One may be using the Multimedia Cable Network Systems (MCNS)/ Data over Cable Systems Interface Specification (DOCSIS) standard, and the IEEE 802.
