I think this is a good question. And think this will definitely help you to choose your modem. If you are using two-way cable modem then there is no need for telephone line. Both upstream and downstream signals carried through cable line. Only you need telephone when you using one-way cable modem. With this one way modem your upstream signals travel thro telephone line to the cable office and then to the Internet. And the downstream signals or your request is sent back to you via cable lines.
Friend, a simple dial up modem is different from cable modem. A cable modem is a small box that connects your computer to the Internet via your local cable television provider. A cable modem has two connections, one that leads to the cable lines outside your home and an Ethernet connection to your computer. A one-way cable modem will also have a telephone line connection.
Technically, cable modems modulate and demodulate RF signals. It receives data in what is known as the downstream signal. This signal usually runs adjacent to other television signals. For proper technical know how, you can refer to some modem processing sites.
I think yes, you can. Since television and the cable modem operate on separate frequencies of the available cable bandwidth, you will be able to watch television and browse the Internet at the same time.
Network speeds can reach up to 27 Mbps, but speeds will also depend on the service level to which you subscribe. As per my knowledge, for downloading web pages and multimedia files and participating in newsgroups requires much more bandwidth than sending web page requests or e-mail.
Yes it is definitely true. Cable modems can connect to the Internet and download information much faster than a dialup modem. It will take a cable modem user milliseconds to connect to the Internet while it will take a dialup modem user about a minute.
