A managed switch is a type of network switch that allows users to configure, manage, and monitor their local area network (LAN). Unlike an unmanaged switch, which operates with default settings, a managed switch provides advanced features such as VLAN support, traffic prioritization, and network monitoring. This makes it ideal for businesses that require better control over their network performance and security. These switches can be accessed through a web interface or command-line interface, enabling network administrators to make real-time adjustments. By using a managed switch, organizations can optimize their network traffic, enhance security, and ensure reliable communication between devices like computers, printers, and servers.
