What Does A Modem And Router Do?
2 major components of a system that gets your mobile or home computer connected to the World Wide Web are the router and modem. The modem is communicating with your ISP or Internet Service Provider. It’s called as cable modem if it is connecting to your cable provider via coaxial cable, it is a DSL modem however if it’s connected to your phone line. Your modem will necessarily depend on infrastructure capability of your ISP which can either be satellite or fibre.
On the other hand, the router shares this internet connection among other devices in your office or home. If it’s wireless and creates a WiFi network, then devices can connect to it. The router can be provided with ports for the Ethernet cables. Whether you believe it or not, the router connects the internet through the modem and is recipient and owner of single IP address on the internet in which servers online can connect.
The routers come with firewalls which are protective barricades towards internet and at the same time, offering protection in hardware format together with software firewall protection that is available on your computer. All brands of modems and routers as well are basically working the same way except from their cosmetic differences but, there’s wide range of routers and modems that can be chosen from and the prices may vary from 30 dollars to few hundreds.
When you’re currently in the process of choosing a modem, if your ISP provides internet via cable network, then the modem for the cable will be a standard one which is also referred to as DOCSIS 3.0 as being the latest format across all the brands. In case that it is a DSL connection, you should go for a VDSL connection that is capable of delivering speeds of greater than 15mbps and ADSL connection for a lesser speed.
It is important to know the number of available channels. For 1 or 2 users, 4 upload and 8 download channels will suffice while bigger family that are making use of several devices working simultaneously, then 16 to 32 download channels will be the better choice but expect this to cost you more as well.
Believe it or not, it is a lot easier to choose routers as there are only 2 types of technologies used in such including AC which has beam forming technology that directs a beam to your device rather than the radius of the Wi-Fi technology and N technology which is comparatively slower. Buying a modem and router on your own instead of choosing what the service provider offers in exchange for a lower rent is a better deal.
