What are Modems, Routers, and Combos?
If you want to get your home computer or mobile devices connected to the internet, the modem and router are the two important components of the system. With a modem you can communicate with your internet service provider. A cable modem connects to your cable provider through a coaxial cable. Connection to a telephone line makes your modem a DSL modem. Your modem is dependent o the ISP’s infrastructure capability. It could also be fiber or satellite.
A router makes it possible to share internet connection with other devices in your home or office. A wireless router creates a Wi-Fi network that devices can connect to. If there are Ethernet cables, there are also routers which has ports for these. with the modem, a router can connect different devices to the internet. It is the recipient and owner of a single IP address on the internet which servers on the net can connect to.
Routers come with firewalls, which are protective barricades against the internet. The firewall gives protection in the hardware format as an additional protection to that provided by the software firewall in your computer.
A combination of both router and modem are combined in one piece of equipment with ADSL devices.
All modem-router combo brands basically work the same way although there are basic differences in the cosmetics or design of the devices.
You can choose from many different types of modem-router combos with prices varying from less than fifty dollars to those over a hundred.
If your service provider is providing internet through cable network, the modem for cable is a standard one called the DOCSIS 3.0 being the latest format across all brands. For those with DSL connection, if your speed is great than 15 Mbps, the you would go for a VDSL connection and an ADSL connection for lesser speeds.
Routers are easier to choose. Routers use two types of technology. There is a beam forming technology for fast AC which directs a beam at your device as compared to the radius wifi technology. This is better for new devices and old ones too work well on this technology. Speeds can range from 100 Mbsp to 5300 Mbps.
It is always better to buy a modem and router on your own rather than going for what your service provider is providing for a low rent. The difference in internet speed is worth spending a few hundred dollars for.
It is better to have one unit that serves both functions of modem and router, a combo, in other words, than getting a separate modem and router. If you are getting all the features of the best modem and the best router, then you get a good system since different brands can be used together.
