Router

  1. 1. Router<br />
  2. 2. Introduction<br />A router is a device in computer networking that forwards data packets to their destinations, based on their addresses. <br />The work a router does it called routing, which is somewhat like switching, but a router is different from a switch. <br />The latter is simply a device to connect machines to form a LAN.<br />
  3. 3. Router<br />Routers take information that arrives through your broadband signal via a modem, decipher it, and deliver it to your computer. <br />The router will also choose the best route for the data packet so that you receive the information quickly.<br />
  4. 4. Router<br />
  5. 5. How a Router Works<br />When data packets are transmitted over a network (say the Internet), they move through many routers (because they pass through many networks) in their journey from the source machine to the destination machine. <br />Routers work with IP packets, meaning that it works at the level of the IP protocol.<br />

  7. 7. Router Working<br />Each router keeps information about its neighbours' (other routers in the same or other networks). <br />This information includes the IP address and the cost, which is in terms of time, delay and other network considerations. <br />This information is kept in a routing table, found in all routers.<br />
  8. 8. Router Working<br />When a packet of data arrives at a router, its header information is scrutinized by the router. <br />Based on the destination and source IP addresses of the packet, the router decides which neighbour it will forward it to. <br />It chooses the route with the least cost, and forwards the packet to the first router on that route.<br />
  9. 9. Types of Routers<br />Broadband Routers<br />Broadband routers can be used to do several different types of things. <br />They can be used to connect two different computers or to connect two computers to the Internet. <br />They can also be used to create a phone connection.<br />
  10. 10. Broadband Router<br />
  11. 11. Broadband Router<br />If you are using Voice over IP (VoIP) technology, then you will need a broadband router to connect your Internet to your phone. <br />These are often a special type of modem that will have both Ethernet and phone jacks. <br />Although this may seem a little confusing, simply follow the instructions that your VoIP provider sends with your broadband router - usually you must purchase the router from the company in order to obtain the service.<br />
  12. 12. Types of Router<br />Wireless Router<br />Wireless routers connect to your modem and create a wireless signal in your home or office. <br />So, any computer within range can connect to your wireless router and use your broadband Internet for free. <br />The only way to keep anyone from connecting to your system is to secure your router.<br />
  13. 13. Wireless Router<br />
  14. 14. Wireless Router<br />A word of warning about wireless routers: Be sure your secure them, or you will be susceptible to hackers and identity thieves. <br />In order to secure your router, you simply need to come to WhatIsMyIPAddress.com, and get your IP address. <br />Then, you'll type that into your web browser and log into your router (the user ID and password will come with your router).<br />
