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 also depend on the infrastructure capability of your ISP which can either be satellite or fibre.
As for the router on the other hand, it shares the internet connection on several other devices in your home or office. 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 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. 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.
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. 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 persons, 4 upload and 8 download channels will suffice while for a bigger family that are using several devices working simultaneously, then 16 to 32 download channels is going to be the better choice but this will cost more of course.
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. It is a smarter deal for you to buy modem and router on your own than going for what the service provider is offering in exchange for lower rent.
