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.
Cable modems vs. DSL While the computer industry continues to grow, the need for higher speed internet access increases. ... Cable modems run off of the pre-existing coaxial cable that is already wired in most homes for TV. ... When there are many customers in the area that use the cable modem service, it can impact the performance of the cable modem. ... Cable modems and DSL differ in availability. ...
ADSL Versus Cable Modem ADSL (Asymmetric Digital Subscribers Line) and cable modems are modem technologies that have been created to provide faster access speeds for users accessing the web. ... DSL provides services as fast as a cable modem, and in some protocols much faster than a cable modem. ... Although I have written about some of the major problems with ADSL and cable modems, I believe ADSL has more advantages to the service than the cable modem. Since ADSL uses dedicated local bandwidth and a cable modem uses shared bandwidth across a neighborhood, ADSL still beats cable mod...
We have chosen as our project the principle of the modem, intelligent modems, high-speed modems and wireless modems. ... They consist either of a box of electronics connected to your computer by a cable (an external modem), or a card which fits inside your computer (an internal modem). ... Modems must be compatible with your computer type, so if you buy one, make sure you've got the right software and computer cable for your type of computer. ... Future Modem Technology We found in our research of this particular area a very interesting article by Michael Pastore who believes that a...
That is very slow as compared to today's standard 56k dial up modem. 56k modem connections are what most home internet user's use to access the internet. ... Unfortunately not all rural areas have access to broadband internet service providers for their home use. ... Cable modems send the information through a cable similar to the cable that your cable TV comes through. The cable modem connects to an Ethernet cable which connects to your computers network card and you are always connected to the internet as long as your computer is turned on. ... A downside to cable modems is in l...
Dial up is the least expensive access technology that's price is usually between 10 to 30 dollars. ... Cable modems transmit data from the network at about 3Mbps, and transmit data to the network between 500Kbps and 2.5Mbps. Like other modems cable modems convert signals between digital and analog. However, cable modems are much more complex than standard analog modems, because they must contain a tuner. ... Because of multiple users in the same location share the same cable the modem. ...
Over the past year ADSL has begun to be widely installed in telephone networks for always-on Internet access, typically operating at several hundreds of kbps or higher over phone wires up to about 5.5 kilometers in length. ... ADSL has a number of advantages over systems that use a cable television network. ... Where as cable modems are, which work over a giant network (party line) when someone else is receiving data, someone could be listening in on your data signal. ... A television channel has an effective throughput of only about 24 Mbps, greatly limiting its effectiveness under heavy use ...
"If you have access to both services and you're primarily interested in the fastest downloads possible, go for cable, which has very high theoretical throughput. ... The other choice of Internet broadband access is Cable Internet service. ... Cable modems are up to 10-20Mbps download. ... The hardware required is simple, a cable modem and a USB Ethernet adapter. ... Replacing the DSL or Cable modem your ISP provides is a sketchy proposition. ...
A cable modem is a device that allows you to hook up your PC to a local cable TV line and receive data. Cable modem works under the assumption that data traffic is bursty in nature, and several hundred cable modem users can surf at the same time without noticeable loss of performance. ... After a close analysis and comparison of the two technologies, it seems that cable modem has a slight performance advantage over DSL. ... The competition between the cable modem and the DSL (digital subscriber line) has brought out a new stream of options for every type of consumer. ... The focus of this ...
The access to the Internet will be through a cable modem supplied by AT&T. A Linksys single port router will be used as a firewall to isolate the cable modem from the internal computer network. ... The central location should be near a cable connection; this is because the network will connect to the Internet using a cable modem. ... The cable modem is connected to the incoming cable signal using standard RG-59 coaxial cable. The cable modem is also connected to the Linksys router using a cat5 pre-built cable. ...
