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 is referred to as cable modem if it’s connected to your cable provider through 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. Say that it’s wireless and creates a WiFi network, devices in the premises 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.
Routers also come with firewalls which are the protective barricades towards internet and offering protection in hardware format along with software firewall protection that’s available on your computer. Basically, all brands of modems and routers are working the same way except for some cosmetic differences but, there’s range of routers and modems to be chosen from and prices are varying 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. 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.
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. It is better to purchase a modem and router on your own instead of going for what the service provider offers in exchange of low rent.
