What are Modems, Routers, and Combos?
To be able to get your home computer or mobile devices connected to the internet, you will need a modem and a router which are its two major components. With a modem you can communicate with your internet service provider. A cable modem connects to your cable provider through a coaxial cable. Connection to a telephone line makes your modem a DSL modem. Your modem will necessarily depend on the ISP’s infrastructure capability. It could also be fiber or satellite.
Sharing internet connection with other devices in your home or office is made possible through a router. If you have a wireless router, you can create a Wi-Fi network that devices can connect to. If there are Ethernet cables, there are also routers which has ports for these. with the modem, a router can connect different devices to the internet. The recipient and owner of a single IP address on the internet which servers on the net can connect to is the router.
Firewalls or protective barricades against the internet come with routers. With the router firewall, it gives protection in hardware format, in addition to the software firewall found in your computer.
Routers and modems are combine in one piece of equipment with ADSL devices.
There are only a few cosmetic differences with modem-router combos but all brands basically work the same way.
You can find many types of modem-router combos to choose from which vary in prices from those less than a hundred to a few hundred dollars.
If your internet is provided through cable network, then the modem is a standard one called DOCSIS 3.0 which is the latest format across all brands. For those with DSL connection, if your speed is great than 15 Mbps, the you would go for a VDSL connection and an ADSL connection for lesser speeds.
It is easier to choose a router. Two types of technology are used with routers. There is a beam forming technology for fast AC which directs a beam at your device as compared to the radius wifi technology. This is better for new devices and old ones too work well on this technology. The speed can range from 100 Mbps to 5300 Mbps.
Better to buy a modem router on your own rather than paying a low rent from the one that is provided by your service provider. Simply spend a few hundred dollars more and you get a big difference in internet speed.
Instead of getting a separate modem and router, it is better to have one unit that serves both function, a modem-router combo. If you are getting all the features of the best modem and the best router, then you get a good system since different brands can be used together.
