What Does A Modem And Router Do?
The router and modem are the 2 major components of a system that gets your mobile or home computer connected to the World Wide Web. The modem communicates with the 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. The devices can connect to it if it is wireless and creates a WiFi network. 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 too which are the protective barricades towards the internet and is offering protection in hardware format together with software firewall protection that’s 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 are in the process of selecting a modem, if your ISP is providing internet via cable network, then the modem for cable will be a standard one referred to as DOCSIS 3.0 as being the latest format across all the brands. However, if it’s a DSL connection you’d go for a VDSL connection that can deliver 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.
Whether you believe it or not, it is easier to buy routers since there are just 2 types of technologies used in such like N technology which is somewhat smaller and the AC which has beam forming technology that is directing beam to your device instead of its radius. 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.
