The vector stencils library "Cisco switches and hubs" contains 26 symbols of Cisco switches and hubs for drawing computer network diagrams.
"A switch is a device used on a computer network to physically connect devices together. Multiple cables can be connected to a switch to enable networked devices to communicate with each other. Switches manage the flow of data across a network by only transmitting a received message to the device for which the message was intended. Each networked device connected to a switch can be identified using a MAC address, allowing the switch to regulate the flow of traffic. This maximises security and efficiency of the network. Because of these features, a switch is often considered more "intelligent" than a network hub. Hubs neither provide security, or identification of connected devices. This means that messages have to be transmitted out of every port of the hub, greatly degrading the efficiency of the network." [Network switch. Wikipedia]
"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. 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. A hub works at the physical layer (layer 1) of the OSI model. The device is a form of multiport repeater. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision." [Ethernet hub. Wikipedia]
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.

The vector stencils library "Logical symbols" contains 49 logical symbols for drawing logical network topology diagrams.
"Logical topology, or signal topology, is the arrangement of devices on a computer network and how they communicate with one another. How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology. Physical topology defines how the systems are physically connected. It represents the physical layout of the devices on the network. The logical topology defines how the systems communicate across the physical topologies.
Logical topologies are bound to network protocols and describe how data is moved across the network. ... EXAMPLE : twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's token ring is a logical ring topology, it is physically set up in star topology." [Logical topology. Wikipedia]

Cisco Network Diagrams
Cisco Network Diagrams solution extends ConceptDraw PRO software with samples, templates and libraries of vector stencils for drawing the Cisco computer network diagrams.
The vector stencils library "Cisco WAN" contains 15 symbols of wide area network (WAN) devices and equipment for drawing Cisco WAN diagrams.
"A wide area network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using leased telecommunication lines. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. ...
Related terms for other types of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively.
... it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other localised computer networking architectures. ...
WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/ IP deliver transport and addressing functions. Protocols including Packet over SONET/ SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs." [Wide area network. Wikipedia]
