      • When a Hub receives data from one device, it will send it to every device on that network
      • They both connect together a series of devices to form a network
        • This allows data and resources to be shared
      • When a switch receives from one device it has a table storing the addresses of every device connected to that network

      • It adjusts the data sent from the computer into a required format according to protocols
    • Router

      • Reads the data's destination address and looks up in the table all the paths to get to that address
      • In order to send data from one place to another it ahs a table in memory that contains list of all the networks
    • WAP
      • Stands for Wireless Access Point
      • Wireless allows you to be mobile when using devices, however, it is not as fast as a wired connection
