Computer Network.
Computer and Network Examples

A Computer Network is a telecommunication network that allows the networked computing devices to exchange the data using the network links. The most known computer network is the Internet.

The network links or connections between the nodes are set up using the cable media or wireless media. The nodes are the network computer devices, such as the computers, phones, servers.

There are many different types of the computer networks: Personal area network (PAN), Local area network (LAN), Metropolitan area network (MAN), Campus area network (CAN), Storage area network (SAN), Global Area Network (GAN) and Wide area network (WAN).

ConceptDraw PRO is a powerful computer network diagramming and vector drawing software. It provides the Computer and Networks Area for quick, easy and effective drawing the different types of computer network diagrams.

Solutions of the Computer and Networks Area contain many professional looking examples that you can customize for your needs to draw your own computer networks in a few minutes. You can also use the great number of ready-to-use predesigned vector objects from the libraries of the Computer and Networks Area.

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 Network

Network Topologies

When 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.Common Network Topologies Diagram

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. 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 PRO provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.Metropolitan area networks (MAN).

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.Network Diagram Software for Mac OS X and Windows
