A cable modem uses digital communications techniques to modulate and demodulate digital signals to and from (for sending and receiving) frequencies appropriate for transmission over the coaxial cable system. Current cable modem standards support speeds up to 400 megabits per second though the service sold is usually slower than that, usually up to around 100 megabits per second.
In general, a cable modem will offer better and more reliable bandwidth and a wireless modem.
Since this was posted under Cable Modems, I'm assuming that you are asking about the (Data Over Cable Service Interface Specification (DOCSIS) cable modem which allows different cable companies and different cable modem manufactures all to adhere to a uniform set of protocols and modulation schemes to allow for inter and intra market competition. Go to Wikipedia and search DOCSIS for more information if that truly was your question.
You could pay a cable company for Internet and they would supply it to your house. Then you would connect a modem to a tv jack and a router to the modem. Then you have wifi. For more information, you should contact a cable provider near you.
Wireless modems are more susceptible to being broken into than cable modems.
The best way for a person to find out more information about the Motorola Surfboard wireless cable modem gateways would be to contact Motorola directly or through their website. The internet may also give you some information but may not always have the most accurate information.
You are supposed to connect an ethernet cable from the modem to whatever device that needs an online connection and if you have 2 or more items connect the router to the modem with an ethernet cable and then connect the devices to the router with ethernet cables
If you have a lan cable with internet access, no you do not need a modem.
The speed of a cable modem needed to play online games is at least 15Mbps in order to play games seamless. Some games may require more bandwidth depending on configuration.
A switch is useful only when you have more than 1 system to connect to a network or through a cable or DSL modem.
one disadvantage of using satellite for an internet connection is that it experiences delays in transmission (call latency), especially when uploading, more so than DSL or cable modem
Yes you take the internet access from the modem to the computer and move it to the router so the router can allow more access than just to the computer. In the back of the router there are spots for ethernet cables only one is a input and that comes from the modem and should be connected. There should also be 4 or more outputs and one then gets connected to the computer. You will need to buy more ethernet cables. Internet comes from your DSL modem and you need to disconnect your computer to allow the router to be installed. Your computer and anything else is then connected to the router
A router or possibly a data switch can connect two PC's to a DSL or cable modem.
