what is the difference between a router and a modem?

Answer 1

A router uses a broadband connection to your modem (cable) via a Ethernet cable and allows more than one connection in your home/office for more than one computer to connect to the modem to go out on the internet.

Answer 2

A router is purely that - a router. to apply this for internet purposes demands a seperate modem. Modem plugs into telephone socket, router plugs into modem. A modem router - as you have in all probability guessed now - has a modem equipped into it. So with a modem router you purely have one piece of hardware on reveal.

Answer 3

A "modem" is short for modulator/demodulator. What it does is take a digital signal coming out of your computer and transform it in an analog format that can travel over a phone line, DSL, or cable. It as receives analog signals and converts them back to digital. That is what allows your computer to send signals over the Internet.

A router is used when you want to connect severals computers to each other and to share a single Internet connection. Since your computer is normally not talking to the Internet 100% of the time (usually 5-10%), the router keeps track of information coming from the all the computers, send it to the Internet, and then routers the reply back to the right computer. This allows you to share the connection between them all. The router, however, has to be attached to a cable or DSL modem in to work. It stills needs something to modulate and demodulate its signals.

Answer 4

A modem (such as a cable modem) actually negotiates the protocols needed to connect to the internet. The router beteween your modem and computer routes packets between your computer and the internet.

Most new routers have a firewall, which will protect your computer from hackers.

Answer 5

A modem only connect's 1 computer to the internet. A router connect's more than 1 computer and has a firewall.

Answer 6

A modem is a device that takes a signal from a phone line, DSL line, or cable provider, etc., and changes it into something your computer can understand. A router takes that signal, or a signal from any network, and "splits" it (either by physical ports or by wireless, or both) so that multiple computers can use the signal.

Many times, modems and routers are combined into one physical device; lots of broadband modems have wireless routers incorporated into them, for instance.

Answer 7

a modem is what connects ur pc to the internet via an ethernet cable, unless it is wireless enabled. If ur modem is not wireless enabled you can buy a router which is connected to the modem via the ethernet cable you would usually connect to your computer.

In short a router enables a modem that does not have a wireless capability to become wireless

Answer 8

Typically the modems provided by the ISP are also routers. They route the traffic from the ISP to your network. But they only allow one computer to be connected at any given time.

The routers you buy at home typically do two things. #1, they allow multiple computers to be connected to the internet. #2, they usually provide a firewall to protect you from intruders on the internet.

Answer 9

a router has multiple outputs while a modem has one output for a computer or an xbox or something
with a router you can plug in the computer for internet accesand have a phone connection to it

Answer 10

modem, an ancient modulator demodulator I think, for when internet was slower than you can type the letters, at least the 300baud one I got for 1.65 or whatever was

a router is also an ancient device (no I'm thinking hub), sorry routers send info packets to the appropriate machine so many pcs can share the fast cable connection
