Show answer & explanation

Correct answer: C

Explanation

The correct answer is switch i.e.

  • A network switch is a device that operates at the Data Link layer of the OSI model—Layer 2.
  • It takes in packets being sent by devices that are connected to its physical ports and sends them out again, but only through the ports that lead to the devices the packets are intended to reach. They can also operate at the network layer--Layer 3 where routing occurs.
  • Switches are a common component of networks based on Ethernet, Fibre Channel, Asynchronous Transfer Mode (ATM), and InfiniBand, among others. In general, though, most switches today use ethernet.
