[ddanny]

Ok im good with computers bu the internet not to good i just want to know do i really need a modem or just the router? And if i just need the router if im using my ps3 and my ipad and computer would it slow down? Or i need both for the internet to work good?

it depends. Do you need to use wifi connection to your wireless devices through your modem? If yes, you require a router.
If you are downloading something on your pc, surely it will have impact on other devices like your downloading speed will be slowed down on pc if at the same you are downloading something on your ipad.

What you need is totally dependent on what type of service you have from the ISP.

Generally, the chain goes like this:
ISP -> modem -> router -> devices
Often, the modem and router are in the same little physical box.

The 'modem' converts the signal the ISP delivers (coax/fiber/DSL) into something that the router and devices can understand. MOdulator/DEModulator.

For Time Warner (or Cox or Comcast, etc) it is advisable to buy something on their approved list of devices. Otherwise, they may not assist if you have to call them with a problem.
