Virtual networks.
Computer and Network Examples

A Virtual network is a computer network that consists of virtual network links, i.e. between the computing devices there isn't a physical connection.

Well known forms of network virtualization are virtual networks based on the virtual devices (for example the network based on the virtual devices inside a hypervisor), protocol-based virtual networks (VLAN, VPN, VPLS, Virtual Wireless network, etc.) and their combinations.

VLAN (Virtual LAN) is a logical LAN (local area network) based on the physical LAN that is divided on a multiple logical LANs using a VLAN ID.

VLAN can be on a VPN (virtual private network). VPN consists of several remote end-points (such as routers, VPN gateways of software clients) that are connected by the tunnel over another network. Two connected end points form the PTP VPN (Point to Point Virtual Private Network), more than two end points form a Multipoint VPN.

VPLS (Virtual Private LAN Service) is a specific type of Multipoint VPN. They can be Transparent LAN Services (TLS) that provides geographic separation and Ethernet Virtual Connection Services (EVCS) that provides geographic separation and VLAN subnetting.

Virtual Wireless network is a set of Wireless Access Points that behaves as one. Computer and Networks Area for ConceptDraw DIAGRAM provides professional looking examples, the libraries with ready-to-use predesigned vector stencils to help you create the Virtual Networks quick, easy and effective.

Personal area (PAN) networks. Computer and Network Examples →

All computer networks differ by various params, and their size is one of them. As global area networks are the biggest, personal area (PAN) networks are the smallest. Personal computers, smartphones and other devices that have possibility to connect to Internet form a personal network. This diagram was created using ConceptDraw Computer Network Diagrams to represent a typical components of Personal area network. A personal area network (PAN) is the connection of IT devices around an individual person. This sample of personal area network involves a notebook, a personal digital assistant (PDA), and a portable printer. Commonly a PAN contains such wireless devices as mouse, keyboard, smartphone and tablet. A wireless connection is typical for a PAN.Personal area (PAN) networks

Hybrid Network Topology →

Every corporate network is unique, though there are guidelines and best practices in developing networks. As it is quite difficult to implement a pure topology within a company, using a hybrid network topology is considered a better solution. As a rule, such network assembles advantages and features of source topologies. This diagram is an example of the Hybrid network. This type of network topology means a conjunction of other network topologies. Such as star-bus, ring-mesh topologies, etc. It should be obviously diverse networks. The final computer network inherits both advantages and disadvantages of its ingredients. Using the ConceptDraw Computer and Networks solution including vector graphic libraries and templates one can develop professional custom network diagrams of any topology and complexity.Hybrid Network Topology *

Campus Area Networks (CAN). Computer and Network Examples →

If we divide computer networks by scale, we get several main categories. The smallest network is PAN, as it connects personal devices themselves, and as the number of users grows, a local area network can be recognized, and campus area networks (CAN) connects several local networks located within some area like a university or a corporation. Computers connected to CAN share public educational materials and list of CAN network examples includes such prestigious universities like Stanford and Carnegie Mellon. This is an example of a computer network diagram created for a campus area network. It was created using using ConceptDraw solution for the Computer and Network diagramming. The specific of this sample campus network is its distribution. It is rather broad to embrace a big campus territory. This diagram can be applied as a template for designing custom area network topology diagram for a particular educational institution.Campus Area Networks (CAN). <br>Computer and Network Examples *

Metropolitan area networks (MAN). Computer and Network Examples →

A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks. Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.Metropolitan area networks (MAN).

Network wiring cable. Computer and Network Examples →

To connect two or more network devices are used the network cables. There are more different types of the network cables: Coaxial cable, Optical fiber cable, Twisted Pair, Ethernet crossover cable, Power lines and others. They are used depending of the network topology, size, protocol. This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.Network wiring cable. <br>Computer and Network Examples *

Hotel Network Topology Diagram →

A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network. On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.Hotel Network Topology Diagram *
