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 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 also depend on the 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 could be provided with ports for 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. In reality, all brands of modems and routers available work in the same way except for the fact that they are different in cosmetics but, there are huge range of routers and modems that can be chosen from and its prices might vary from 30 dollars to few hundreds.
Say that you are currently looking for a modem to be chosen, if your ISP offers internet via cable network, then expect the model for the cable to be a standard one which is called 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.
The number of available channels is also important. For 1 or 2 users, 4 upload and 8 download channels will suffice but for big families that have several devices working simultaneously, 16 to 32 download channels will be the ideal choice but it will cost you more obviously.
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.
