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.

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.
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.

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.

Wide area network (WAN) topology. Computer and Network Examples
A Wide area network (WAN) is a telecommunication network that is used for connecting computers and covers a wide geographical area. WANs often contain a few smaller networks (LANs, MANs, etc.). The packet switching and circuit switching technologies are effectively used in WANs.This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Wide area network topology.

Home area networks (HAN). Computer and Network Examples
A Home Area Networks (HAN) is a type of local area network that is used in an individual home. The home computers can be connected together by twisted pair or by a wireless network. HAN facilitates the communication and interoperability among digital devices at the home, allows to easier access to the entertainments and increase the productivity, organize the home security.This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the home network diagram.

Wireless network. Computer and Network Examples
A Wireless network is a type of the computer network that uses the wireless connections for connecting network nodes for data transfer. The wireless networks are very useful, inexpensive, popular and widely used. They are easy setup and do not require the cables installation.Using the solutions of the Computer and Networks Area for ConceptDraw DIAGRAM you can design the wireless network diagrams of any complexity quick and easy.
