What is a Local Area Network?

Examples of LAN Diagrams

Local Area Network (LAN) is a network which consists of computers and peripheral devices connected each other and to the local domain server, and covers a little territory or small number of buildings, such as home, school, laboratory, office, etc. LAN serves for few hundreds of users. It includes many cables and wires, and demands to design previously a Network diagram. All local area network devices can use the shared printers and disk storage.

Cisco network topology - Vector stencils library

The vector stencils library "Cisco network topology" contains 89 symbols of Cisco network devices and design elements for drawing computer network topology diagrams.
"There are two basic categories of network topologies:
(1) Physical topologies,
(2) Logical topologies.
The shape of the cabling layout used to link devices is called the physical topology of the network. This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling. The physical topology of a network is determined by the capabilities of the network access devices and media, the level of control or fault tolerance desired, and the cost associated with cabling or telecommunications circuits.
The logical topology in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices." [Network topology. Wikipedia]
The symbols example "Cisco network topology - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

What is a Virtual Private Network?
VPN Diagram Examples

Virtual private networks (VPN). <br>Computer and Network Examples *

A Virtual Private Network (VPN) is a network that allows the private networks at a remote location securely connect to the public Internet and provide access only to the intended recipients for transmitting data. VPN is built by creating the virtual point-to-point connection using the dedicated connections, traffic encryption or virtual tunneling protocols. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual Private Network (VPN) diagram.

All listed types of plans will be a good support for the future correct cabling and installation of network equipment.

Star Network Topology

Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful. The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

Hotel Network Topology Diagram

Network topology is a layout of various elements of computer network, such as nodes, links, routers, etc. It is a network topological structure which can be depicted logically or physically. Physical topology shows the physical location of network's components and cable connections between network nodes. Logical topology describes the data flows, the circulation of signals in physical topology. The physical and logical topologies for two networks can be identical, while their physical interconnections, the distances between nodes, transmission rates, and/or signal types may be differ. ConceptDraw DIAGRAM with Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park lets you design physical and logical network topology diagrams for wireless and wired computer communication networks located in various premises, including the hotels.

10Base-T star topology - Network diagram

"Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer, which act as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected; this central node provides a common connection point for all nodes through a hub. In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch. The switch is the server and the peripherals are the clients. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star." [Star network. Wikipedia]
The computer network diagram example "10Base-T star topology" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

Wide area network (WAN) topology. Computer and Network Examples

Wide area network (WAN) topology. <br>Computer and Network Examples *

Wide area network (WAN) is a type of telecommunication network, which is used to connect the computers on a wide geographical area. WANs are quite popular and widely used networks, the most known and bright example of WAN is the Internet. They offer exceedingly convenient and quick way of exchanging information and data between employees, suppliers, and clients that are geographically remote each other. WANs are often constructed from several smaller networks (LANs, MANs, etc.) and use effectively different packet switching and circuit switching technologies. ConceptDraw DIAGRAM is a powerful network diagramming software. Including Computer and Networks Area with extensive variety of solutions, ConceptDraw DIAGRAM offers a lot of ready-to-use predesigned vector stencils, wide set of examples and samples, helping the business and government entities effectively design professional-looking Wide area networks (WANs) and Wide area network topology diagrams of any complexity.

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 DIAGRAM 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 DIAGRAM 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 DIAGRAM tools. There are plenty of web Visio-like diagramming software available.
