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.
Example 1. Virtual network.

Network Diagram Software LAN Network Diagrams & Diagrams for LAN Physical Office Network Diagrams
Local area network connects computers and other network appliances within an area, such as office building or a campus. It can be difficult to provide such network without a predesigned plan. For these purposes you can use network diagram software, which helps you to create LAN network diagrams and office network diagrams quickly and effortless. This will speed up your work and you can save the diagram for the future network improvements. The following diagram illustrates a network topology of the small office. LAN configuration has a star topology. The local network joins 8 computers among which are several desktop PCs, laptop, two iMacs and iBook. The end-point devices are divided into three groups. Each group is connected to its hub. There is a network printer and a modem, which are interconnected with other devices through a network server. Each computer on the LAN can access the server through a corresponding hub.

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.

Network Diagram Examples
When studying computer science, it is important to have good training manuals. To understand how the networks and data links work, you will probably need a set of network diagram examples depicting all the possible interconnections between network devices. You can find them on Internet or try to create your own. This example of a network topology diagram was made using ConceptDraw Computer and Network Diagrams solution. It represents a bus topology network diagram. A bus topology means that computers and peripherals in the network are connected to a mutual cable (backbone). This topology is often used for small networks. This diagram was designed using vector libraries of network equipment symbols. They also can be applied while creating various LAN and WAN diagrams.
