What Is A Router

What is a router? You don't need to be a network administrator to know the basics of using a router. A router is a simple device made to send data packets back and forth along the network, which connects computers together making a network. 

1. How a router functions. The router works on the IP protocol network level. What does this mean exactly? The information is sent from the computer to another computer in data packets. These data packets go along the network and the router distributes the information accordingly. So when data (also called packets) are sent across a network it is sent to another network sent by the router without mistakes. It works very efficiently and accurately. You can think of the internet as millions of computers connected together using a large network. The router is widely used in LANs, WANs and wireless networks. 
2. Why use a router. If you want to set up a network you need a router. A router will connect all the computers together creating a LAN, WAN or wireless LAN.  Now a days you can get a good quality wireless router for home use. There are many good brands to choose from when purchasing a router. All are good, the choice is yours. Just make sure you get a router that is compatible with 802.11g, if getting a wireless router. 
3. Using a router for workplace. A router is widely used in the workplace. In fact, it is normal to have LANs as well as WANs. Many places have integrated wireless routers. Usually the network administrator will choose the equipment and install the new equipment, but you can see how they connect them to get an idea of how it works.
