Local area network (LAN). Computer and Network Examples
A local area network (LAN) is a devices network that connect with each other in the scope of a home, school, laboratory, or office. Usually, a LAN comprise computers and peripheral devices linked to a local domain server. All network appliances can use a shared printers or disk storage. A local area network serve for many hundreds of users. Typically, LAN includes many wires and cables that demand a previously designed network diagram. They are used by IT professionals to visually document the LANs physical structure and arrangement.ConceptDraw - Perfect Network Diagramming Software with examples of LAN Diagrams. ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Local Area Network diagrams.

Internet Connectivity. Computer and Network Examples
The 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 DIAGRAM 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).

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.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual network.

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.

Campus Area Networks (CAN). Computer and Network Examples
A campus network provides wireless access to the Internet or LAN to users located in two or more buildings or in the open space surrounding those buildings. A campus network is usually set in the campus of a university, but the same kind of planning and design can be applied for other purposes. For example, the campus network can used for an office or industrial park, in a public place like a supermarket with an entertainment center, even on a farm. Another form of temporary campus network can exist during special events such as music festivals or rallies.The elementary campus networks arise spontaneously: the radio signals from the access points, which provide network inside the building are not limited to its walls, so any user in the backyard can also get wireless network access. The larger and more complex campus network may have additional access points in places specially chosen for serving clients, i.e., on the lawn in front of the college or in a coffee shop around the corner.

Physical network. Computer and Network Examples
Physical network represents the computer network topology that includes the computer devices, location and cable installation. Physical network includes the actual nodes, segments and hosts.This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Physical star network.

Digital Communications Network. Computer and Network Examples
The digital communication is a physical transfer of the data over a point-to-point or point-to-multipoint communication channel. Channels can be copper wires, optical fibres, wireless communication channels, etc. The data are realized as electromagnetic signals (radiowave, microwave, electrical voltage, etc.).This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Digital Communication Network diagram.
