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 purpose of the modem is to communicate with 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 depend necessarily 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 can be provided with ports for the Ethernet cables. The truth is, router is connecting to the internet via 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.
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.
It is a lot easier to choose routers as there are only 2 types of technologies used in such like AC which has beam forming technology that is directing a beam to the device instead of the radius of the Wi-Fi technology and the N technology which is relatively 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.
