What is the difference between a managed and an unmanaged switch?

An unmanaged switch is a simple device that allows devices to talk to each other immediately—just plug it in and go. A managed switch offers advanced features for IT professionals and prosumers, allowing you to configure, monitor, and manage your Local Area Network (LAN) traffic. If you have a complex network with VoIP phones and guest WiFi, a managed switch gives you the control you need.
