What’s a MODEM?

The modem is your house’s gateway to the World Wide Web. It is frequently a skinny box with a row of LED icons onto the front, which tells you if it is on and attached to the worldwide Web. The title is short for modulator-demodulator-a term leftover in dial-up times when modems functioned by regulating telephone signs into frequencies that could send electronic data.

Now, most modems use broadband connections such as cable or satellite to transmit information. There are various kinds of modems constructed to match unique connections. If your online service provider (ISP) uses fiber or cable net, you will have to plug in a cable to the back of your modem, and if you still use a digital subscriber line (DSL), you are going to need to plug into a telephone line.


  • Connects to an ISP.
  • Compatible especially using the ISP.
  • Converts the signal from the ISP into a universal one that a computer can use.


  • It cannot make a local community.
  • Does not run WiFi.
  • Does not connect many devices to the Web.

What’s a ROUTER?

You can link to the net with only a modem provided that you do not mind plugging your device into the Ethernet port. But if you would like to give net to all of the notebooks, desktops, and smartphones at your house at precisely the same time, you’re going to want a router.

Routers typically lie flat and have antennas sticking out of these. The router hooks up to a modem via an Ethernet cable and functions as a conduit between the lead and your home network. After connecting your devices, the router “paths” your modem’s media visitors their way, either via Ethernet cables or wirelessly via WiFi (precisely what the antennas are for). The router also functions in another direction by routing information sent from the computer back to the Internet connection.


  • Creates a local area network (LAN).
  • Splits an online link to some devices.
  • Host’s WiFi.
  • Restoring a firewall.
  • Connects into a VPN.


  • It cannot link directly to the net.
  • Does not decode the signal in the ISP.

What exactly does a modem do, and how can it be distinct from what a router does?

A modem is a modulator/demodulator. Data transmission online happens via wires in analog format. But digital devices such as phones and computers know digital transmission. A modem would be the connection between the Internet and a computer system; the modem modulates and demodulates signals to convert analog signals to digital and vice versa. This allows devices to communicate online.

Modem vs Router Function

As shown in the image above, a modem transmits and receives information through cable or telephone lines and also is used to link a computer or a whole home computer system into the Internet Service Provider (ISP), including Comcast or Verizon FiOS. Nowadays, most Internet connections are delivered and broadband through cable; however, DSL connections also function precisely in an identical manner – both the cable and DSL Internet connections take a modem.

If you have one computer connecting to the world wide web, you might not require a router. Modems have an ethernet interface; a pc can connect directly into a modem’s ethernet port through an ethernet cable and become on the Web.

However, maybe not all computers have an ethernet port. And it’s a lot more common for there to be heaps of devices in a home or workplace which will need to connect to the Web. They can not all link directly to the modem; an intermediary apparatus is demanded – a router.

A router makes a network and enables multiple devices to link to the system. The router is connected to the modem; therefore, all devices on the router may connect to the Web through the modem-and connect. The router is smart enough to deliver packets of information to multiple destinations.

Routers for your home and small office marketplace are wireless-enabled; wireless routers make it possible for devices to link to them through WiFi. Many routers also have multiple ethernet interfaces that allow wired links, which is considerably faster than WiFi; at a house network, wired connections are ordinarily employed for gaming consoles or TVs for much better video streaming functionality.


A modem may only connect to a single device: either a home PC or a router.

A router may connect to multiple devices in a system, either via Ethernet cables or via WiFi.

Wireless Modem

Until today we’ve talked about the typical home or small office system. There’s another domain in which you get Internet service and utilize a modem-your mobile phone. Mobile phones have a built-in modem that translates the analog signal from radio waves, which are used to communicate with mobile towers. This is also referred to as a wireless modem and should not be confused with all the incorporated modem/wireless router employed in house networks.


A modem doesn’t display the information that it encodes or decodes, so it moves on any possible danger to connected computers.

Routers analyze data packets to ascertain their destination and comprise firewalls to screen out attacks on the system.


Taking a look at the best-selling wireless routers available on Amazon, you’ll locate routers ranging from $19.98 to $150 for innovative routers or $250 for 3-pack “net” systems that pay bigger homes.

The best-selling modems on Amazon range from $40 to about $200.
