  • 1. Interconnecting devices  Interconnecting devices are devices that allows one computer device to communicate with other computer devices.
  • 2. Router  Router is used to connect a wireless device to a network without using cables.  Also allows users to share data on the internet and also finds the fastest path for data to travel.
  • 3. Switch  Switch is a devices used to create a network.  A switch has an internal address table, called the CAM table, what is uses to send data to its destination, by using their Mac address.
  • 4. CAM table  The CAM table is a table within the switch that records all mac address from the network.  If it does not have the mac address it broadcast the data and when it receives a reply it records the mac address.  The CAM is stored in the switch’s RAM what is volatile, meaning if the switch is turned off the data is all lost.
  • 5. Hub  Hub is another device used to create a network.  However unlike the switch it can’t read Mac address, so the data is sent to all devices on the network, the one its going to would accept it, while the others decline it.
  • 6. Bridge  Bride is a device used to connect two or more LAN networks together.  The Bridge records the source destination of all the data received.
  • 7. Wireless access point  Wireless access points connects wireless devices to LAN network.  However it does not provide IP address or have firewalls, like the router does, but it does lock out those who don’t have wireless key.
