You would need a cable modem when you want to connect to a cable internet service.
The cable modem that you got from your service provider is adequate. You might get a little faster service with another modem but it will probably not make much of a difference.
You must subscribe to an internet service and have WiFi modem or router or connect an ethernet cable to your PS3 from a router or a Modem with internet service
Yes, you can own your own cable modem, but most television and internet providers allow you to use a cable modem for free if you sign up for their service.
No. A modem is used for dial up.
I think that high speed wireless is worse then a cable modem, since it will go out during a very bad thunderstorm or any bad weather. With a cable modem you are less problems to occur an outage.
Satellite Internet does not use a cable modem. The service doesn't use cable or phone wiring in the house. There is a satellite on the property and wiring that brings the service into the house. The provider would supply the necessary peripherals to connect to the Internet.
You add a wireless router to your cable modem and you're in business. The router can run from $50 to $120 and you need an Ethernet cable to connect the devices
You can connect your laptop to the Internet with a cable modem, sure. You will need an Ethernet cable to do that. If you want wireless internet, you will need a cable modem, and a wireless router as well.
You first need to sign up for an Internet Service Provider (ISP). They will hook you up with service and give you a cable or dsl modem. From there, install the cable or dsl modem, install the software they gave you on your computer, plug in the cable or dsl modem. you know should have HIGH SPEED!
I use a cable modem, but you have to have service provided from a Cable internet company. It gives very fast Internet speeds.
Your question presupposes that you have subscribed to cable internet service, and that the provider has run a cable to your home. It also presupposes that you have a cable modem. If these suppositions are correct, you just have to run coax between the cable jack on the wall and the cable modem. Then you need to connect the modem to your computer via USB, FireWire, or whatever interface your modem and computer have in common. FriPilot
