Diagram of a Basic Computer Network. Computer Network Diagram Example

What is a computer network? This is a set of devices and systems that are connected to each other (logically or physically) and communicate with each other. This could include servers, computers, phones, routers, and so on. The size of this network can reach the size of the Internet, and can consist of only two devices connected by a cable.
This sample shows the connection scheme of the home WLAN equipment to the Internet.

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.

Personal area (PAN) networks. Computer and Network Examples

A Personal area network (PAN) is a computer network that is used for data transmission between different personal devices (computers, telephones, digital devices, etc.) and for connecting to the higher level network and Internet. PANs can be wired with computer buses (USB and FireWire). A wireless personal area network (WPAN) can be made using the network technologies such as Bluetooth, IrDa, UWB, Z-Wave, ZigBee, Body Area Network. A personal area network handles the interconnection of IT devices at the surrounding of a single user. Generally, PAN contains from following such appliances: cordless mice and keyboards, cordless phone, Bluetooth handsets.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Personal area network.

Computer Network Architecture. Computer and Network Examples

The network architecture and design specialization will help you gain the technical leadership skills you need to design and implement high-quality networks that support business needs.

ConceptDraw DIAGRAM Network Diagram Tool

With ConceptDraw DIAGRAM you can diagram a network or create a computer network diagram using specialized libraries of network components such as computers, hubs, smart connectors etc. that simulate network design topologies and devices, network architectures (all these shapes are parts of network diagram tool ConceptDraw DIAGRAM).

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.

Network Concepts

ConceptDraw DIAGRAM diagramming and network drawing software extended with Network Layout Floor Plans Solution from the Computer and Networks Area is the best for visually representing and explaining the basic network concepts.
