What are Modems, Routers, and Combos?
The modem and router are two major components of the system that gets your home computer or mobile devices connected to the internet. With a modem you can communicate with your internet service provider. A cable modem connects to your cable provider through a coaxial cable. A DSL modem is connected to your telephone line. 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. Sometime routers have ports for Ethernet cables. 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.
Routers have firewalls that protect them against the internet. The firewall gives protection in the hardware format as an additional protection to that provided by the software firewall in your computer.
ADSL devices combine both router and modem in one piece of equipment.
All modem-router combo brands basically work the same way although there are basic differences in the cosmetics or design of the devices.
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.
The DOCSIS 3.0 is the latest format for the standard modem for cable, if your service provider provides internet through cable network. 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.
There is no difficulty in choosing a router. Routers use two types of technology. These two technologies are the beam forming technology which directs a beam at your device and the other is the radius Wi-Fi technology. New and old devices work well on this technology. The range of speed are from 100 Mbps to 5300 Mbps.
A modem router bought on your own is much better than the low renal you pay for the modem router provided by your service provider. It is worth spending a few hundred dollars for a great 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. It helps in a tidy system, provided you are getting all the features of the best modem and the best router, because different brand can be used together.
