Why Equipment Aren’t As Bad As You Think

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 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 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. If it’s wireless and creates a WiFi network, then devices can connect to it. The router may 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. All brands of modems and routers as well are basically working the same way except from their cosmetic differences but, there’s wide range of routers and modems that can be chosen from and the prices may vary 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. If it’s a DSL connection on the other hand, you’d go for a VDSL connection that could deliver speeds of greater than 15mbps and ADSL connection for 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 better to purchase a modem and router on your own instead of going for what the service provider offers in exchange of low rent.
