Networking Devices include all the devices that connect the end-user devices together to allow them to communicate • Example of network devices include hubs, switches, and routers.

  6. Network devices • Network devices provide transport for the data that needs to be transferred between end-user devices • Network devices provide extension of cable connections, concentration of connections, conversion of data formats, and management of data transfers • These devices are the following: • Repeaters • Hubs • Bridges • Switches • Routers

  7. repeaters Repeaters used to regenerate the signal

  8. HUBs Hubs concentrate connection

  9. bridges Bridges convert network transmission data formats as well as perform basic data transmission management

  10. switches Switches add more intelligence to data transfer management

  11. routers Routers have all the capabilities listed above and can connect to WAN
