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 is called as cable modem if it’s 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.
The router on the other hand is sharing 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 may be provided with ports for 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.
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. 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’re currently in the process of choosing a modem, if your ISP provides internet via cable network, then the modem for the cable will be a standard one which is also 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.
Being able to know the number of channels available is vital. 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 better to purchase a modem and router on your own instead of going for what the service provider offers in exchange of low rent.
