Personal area (PAN) networks. Computer and Network Examples

Personal area network (PAN) is a network organized on a limited area and used for data transmission between various personal devices, such as computers, tablets, laptops, telephones, different digital and mobile devices, etc. and also for connecting to higher level network and Internet. PAN is used to manage the interconnections of IT devices which surround a single user and generally contains such appliances, as cordless mice, keyboard, phone, and Bluetooth handsets. PANs can be wired with computer buses, or wirelessly connected to the Internet using such network technologies as Bluetooth, Z-Wave, ZigBee, IrDa, UWB, Body Area Network. PANs have a lot of pros and cons, they are expedient, lucrative and handy, but sometimes have bad connection with other networks on the same radio bands, Bluetooth has distance limits and slow data transfer speed, but is comparatively safe. ConceptDraw PRO diagramming software supplied with numerous solutions of Computer and Networks Area included to ConceptDraw Solution Park perfectly suits for designing the Personal Area Networks.

Network Topologies

Network topology is a topological structure of computer network, which can be physical or logical. The physical topology depicts location of different computer network elements such as computers, cables and other devices. The logical topology visually displays network dataflows from one device to another. Sometimes network logical and physical topologies can be the same. ConceptDraw PRO diagramming and vector drawing software is powerful for drawing network maps and network topologies diagrams of any kinds and complexity thanks to the Computer Network Diagrams solution from the Computer and Networks area. ConceptDraw STORE proposes collection of network icons libraries and a lot of Network Topology Diagram examples, samples and templates which were created at ConceptDraw PRO software specially for Computer Network Diagrams solution. There are six basic types of the network topologies: Bus, Star, Ring, Mesh, Tree, Fully Connected. You can fast and easy design professional-looking diagram for each of them using the ConceptDraw PRO tools. There are plenty of web Visio-like diagramming software available. Web based diagrams software can be powerful, but sometimes it is essential to have desktop software. One of the most advanced diagrams tools like Visio for Mac OS is ConceptDraw PRO app.

Point to Point 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. This sample shows the Point-to-point network topology. Network topology is the topological structure of the computer network. Point-to-point network topology is a simple topology that displays the network of exactly two hosts (computers, servers, switches or routers) connected with a cable. Point-to-point topology is widely used in the computer networking and computer architecture.

Network Topology

Network topology describes a way of organizing the physical connectivity of computers and other network components. All networks are built based on basic topologies: bus, star, ring, mesh. The basic topologies themselves are not complicated, but in practice we often face with their complex combinations. A particular choice of one or another topology affects the composition of necessary network equipment, opportunity of network expansion and method of network management. Bus topology is widespread and the most simple, it uses a single cable along which are connected all computers. In Star topology each computer is connected by a separate cable to common hub device located in a center of network. In networks with Ring topology, the data are transmitted around the ring from one computer to another, usually in one direction. In Mesh networks, only the computers with intensive data exchange are connected. ConceptDraw PRO software extended with powerful tools of solutions included to Computer and Networks area, contributes to high-quality design Network Topology Diagrams of different types.

Fully Connected Network Topology Diagram

Fully Connected Network Topology (Complete topology, Full mesh topology) is a network topology characterized by existence of direct links between all pairs of nodes. The Fully connected network including n nodes, contains n(n-1)/2 direct links. This topology is mostly used in military applications. It is a quite expensive network technology and is extremely impractical for the large networks. But when it is set, it provides a high degree of reliability thanks to the large quantity of redundant links between nodes and so multiplicity of paths for the data. The two-node network is also considered as a Fully connected network. Computer Network Diagrams solution from Computer and Networks area of ConceptDraw Solution Park offers the predesigned vector stencils libraries, examples and templates for easy designing various Computer network topology diagrams for wired and wireless networks, including the Fully connected topology. This solution is intended to help computer network designers and engineers perfectly illustrate network documentation, reports, presentations, etc.

Using Both Wired and Wireless Connections

The ConceptDraw Wireless Networks solution helps users to quickly transit from an idea to the implementation of a both wired and wireless computer networks.

Overlay networks. Computer and Network Examples

An Overlay network is a computer network that is built on the top of another network. The nodes of the overlay network are connected by virtual or logical links. Overlay networks are widely used in telecommunication. They also allow to improve Internet routing. Using the solutions of the Computer and Networks Area for ConceptDraw PRO with wide set of ready-to-use predesigned vector stencils and examples you can design anyone overlay networks quick and easy.

Mesh Network. Computer and Network Examples

A Mesh Topology is a computer network topology that is based on the cells concept, in which each workstation connects with several other workstations of the same network with the possible to accept the switch functions for other workstations. 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 the Mesh Network.

Diagram Physical Topologies

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. This diagram shows the physical network topology. Network topology is the topological structure of the computer network. The physical network topology depicts the placement of the components in the network. It shows the configuration of cables, computers, and other devices.
