Communication Network Topology
This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
Computer and Networks solution provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment. LAN (local area network) is a computer network that connects computers in a limited area using the network media. WLAN (wireless local area network) is a computer network that links two or more devices and provides the connection to the Internet through the access point.
Example 1. Communication Network Topology
This sample shows the communication network topology.
Network topology is the topological structure of the computer network.
A communication network topology is defined by the evaluating costs of the states. Each state represents the possible distribution of the hubs and remote nodes to nodes of the communication network.
Using the Computer and Networks Solution for ConceptDraw PRO you can create your own professional Computer Network Diagrams quick and easy.
The Computer Network Diagrams produced with ConceptDraw PRO are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

Network Diagram Software LAN Network Diagrams & Diagrams for LAN Physical Office Network DiagramsLocal 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.
Network Diagram ExamplesWhen 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.

Internet Connectivity. Computer and Network ExamplesThe Internet Connectivity of the computers, mobile devices, computer networks to the Internet enables the users to access the various Internet services. There are many ways and technologies of the connection to the Internet with different data signaling rates: Wireless, Ethernet cable, Optical fiber, Dial-up, DSL, broadband Internet access, etc. This example was created in ConceptDraw PRO using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park and shows how the customers connect to ISPs and ISPs connect between the tiers (peering and transit).
Network TopologiesWhen describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.
Fully Connected Network Topology DiagramThere are several basic topologies including bus, star, point-to-point, ring and a hybrid. Two computers can form a fully connected network topology, and as the number of network nodes increases, the network diagram gets more complicated. This type of topology is also called a full mesh. This is a visual example of a computer network built using a mesh topology. This diagram presents the schematic structure of the full mesh network topology. A common mesh network topology means that each network device is connected with several points in the network, so if the one node of the network goes down, it does not cause an issue with an operability of the entire computer network. In a full mesh network topology, every computer or device in the network is interconnected with each of the other devices in the network.
Star Network TopologyNodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical. This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.
Near field communication (NFC). Computer and Network ExamplesNear field communication (NFC) is a wireless communication technology that allows smartphones and other similar devices to establish the radio communication with each other on the short distance around 10 centimeters (4 inches). This example was created in ConceptDraw PRO using the Computer and Networks Area of ConceptDraw Solution Park and shows the Near field communication (NFC) network.
Virtual networks. Computer and Network ExamplesA 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. This example was created in ConceptDraw PRO using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual network.
