A ______ is a networking device that filters network traffic while connecting multiple computer or communicating devices?

Correct option is C

A switch is a networking device that filters and forwards network traffic to specific devices within a network. It connects multiple computers or communication devices and ensures that data packets are sent only to the device they are intended for, enhancing network efficiency and security.

Important Key Points:

1. Switches operate at the data link layer (Layer 2) of the OSI model and sometimes at the network layer (Layer 3) for routing capabilities.
2. They create dedicated communication paths between devices, reducing network congestion.
3. Unlike hubs, switches intelligently filter traffic to send it to the correct destination.

Knowledge Booster:

• Router: Directs data between different networks and provides Internet connectivity.
• Gateway: Connects two different networks and translates data between protocols.
• Repeater: Amplifies signals to extend the range of a network but does not filter traffic.
