Switches, also known as network switches or Ethernet switches, primarily allow for data exchange and communication between network devices. Functions: 1. Data Exchange: Switches can forward and exchange data packets based on network addresses, enabling communication between different network devices. 2. Device Connection: Switches enable multiple devices to be connected to the same local area network, forming a large network system. 3. Improved Network Performance: Switches have a multi-port design that can process multiple data streams simultaneously, greatly improving network transmission efficiency and performance. 4. Data Packet Filtering: Switches use specific algorithms and protocols to filter and screen received data packets, only forwarding targeted packets to the intended device, reducing network congestion and transmission of unnecessary data. Advantages: 1. High Performance: The multi-port design and fast data exchange capabilities of switches result in excellent performance when handling large amounts of data. 2. Flexible Connection: Switches allow for easy connection of multiple devices, making network expansion simple and flexible. 3. Improved Network Security: By filtering and screening data packets, switches can effectively prevent unauthorized devices from accessing the network, thereby enhancing network security. 4. Strong Manageability: Modern switches have network management functions, allowing administrators to remotely manage switches over the network, monitor network status in real-time, and handle faults.
