A router/ wireless router is a specialized networking device connected to two or more networks running software that allows the router to move data from one network to another.
Router functions in an Internet protocol-based network operate at the network layer (OSI Model’s layer 3). The primary function of a router is to connect networks together and keep certain kinds of broadcast traffic under control.
There are several companies that make routers: Cisco, Linksys, Juniper, Netgear, Nortel (Bay Networks), Redback, Lucent, 3Com, HP, Dlink and Belkin just to name a few.
With the right kind of router in your office, you may be able to enjoy faster internet service, help protect your family from cyber threats, and avoid those maddening Wi-Fi dead spots.
You don’t have to be a computer genius to know what a good router has to offer. All it takes is to know what you need it for. Understanding how routers work will help you choose the right equipment for your home network.
A typical Office/home has a range of internet-connected devices personal computers, tablets, smartphones, printers, smart TVs, and more. With your router, such devices form a network. A router directs incoming and outgoing internet traffic on that network.
The information travelling on your network could be a surfing the internet, emails, movies or a live streaming each of which takes up varying amounts of bandwidth (the amount of data that can be transmitted in a fixed amount of time and its measured in bits per second(bps) or bytes per second).
Making sure that information is delivered quickly and correctly is a big task and getting bigger. As you add more and more devices on your network.
How Modems differ from routers.
A router and your devices aren’t the only components on your network. There’s also the modem. In fact, without the modem, all you’d have is your local network with no access to the internet.
The modem’s job is to bring the internet service from your provider into your home. It then connects to your router, delivering that internet connectivity to your home network.
When most internet services were delivered over telephone lines (ADSL), modems enabled communication between the digital devices in your home and the analogue signals used on telephone lines. With today’s internet connections, including cable and satellite, modems play a similar but different role.
Wi-Fi signals within a home largely depend on the size of the home and the barriers that prevent signals from reaching their destinations. Fireplaces, mirrors, and thick walls are just a few common obstacles that block Wi-Fi signals. Look for a router that has the capability to reach the far corners of your home.
Router technology has changed over time. Make sure you have a router that uses the latest technology and has updated firmware (Software that is embedded inside your router. This software provides network protocols, security and administrative controls).
MU-MIMO is one such new technology. It stands for multi-user, multiple-input, multiple-output technology. It allows Wi-Fi routers to communicate with multiple devices simultaneously. This decreases the wait time and improves network speed.
