Managed switches are network switches that offer more control and customization options compared to unmanaged switches. They allow network administrators to configure, monitor, and prioritize traffic on the network, as well as perform other advanced functions such as VLAN configuration, link aggregation, and Quality of Service (QoS) management. Managed switches are ideal for use in complex networks with multiple users and devices, and can provide greater security, reliability, and performance compared to unmanaged switches.
