Hubs neither provide security, or identification of connected devices. Because of these features, a switch is often considered more "intelligent" than a network hub.
This maximises security and efficiency of the network. Each networked device connected to a switch can be identified using a MAC address, allowing the switch to regulate the flow of traffic. Switches manage the flow of data across a network by only transmitting a received message to the device for which the message was intended. Multiple cables can be connected to a switch to enable networked devices to communicate with each other. "A switch is a device used on a computer network to physically connect devices together.
The vector stencils library "Cisco switches and hubs" contains 26 symbols of Cisco switches and hubs for drawing computer network diagrams.
