Each device is drawn and programmed with Visio intelligence to give you complete automation benefits of Visio's features. For example, we never use a photo or non-Visio illustration as a shape. We don't use any shortcuts that are often found in Visio stencils available on other sites. Each and every shape we create is scaled to insert properly into a rack, device, or assembly. The symbols example "Cisco switches and hubs - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.All network equipment stencils available on ShapeSource are produced for our client companies by our Visimation team of shape developers using best practices for Visio drawing and behaviors. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision." The device is a form of multiport repeater. A hub works at the physical layer (layer 1) of the OSI model.
It has multiple input/ output (I/ O) ports, in which a signal introduced at the input of any port appears at the output of every port except the original incoming. "An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment. This means that messages have to be transmitted out of every port of the hub, greatly degrading the efficiency of the network." 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.
