Local area network (LAN). Computer and Network Examples

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. ConceptDraw DIAGRAM is a perfect network diagramming software with examples of LAN Diagrams, templates and predesigned vector objects. ConceptDraw DIAGRAM is the ideal choice for network engineers and network designers who need to draw fast and easy Local Area Network Diagrams, for IT specialists, developers and other IT professionals which need to visualize the communication schemes of LAN and visually document the LAN's physical structure and arrangement in houses, offices and other buildings. Ready-to-use vector objects from Computer Network Diagrams solution will help you design LAN diagrams in minutes.

Computer Network. Computer and Network Examples

A Computer Network is a telecommunication network containing the set of nodes (computer network devices, such as computers, phones, servers) and allows them exchange the data using the network links. There are many kinds of computer networks. The primary difference is their size, according to the scale they can be classified as: Local area network (LAN), Metropolitan area network (MAN), Global Area Network (GAN), Wide area network (WAN), Storage area network (SAN), Campus area network (CAN), Personal area network (PAN). Computer networks also differ by connection method according to the used hardware technology (Ethernet, Wireless LAN, Optical fiber, HomePNA, Power line communication), by functional relationships that exist between network elements (Client-server, Active Networking, Peer-to-peer), by network topology (Tree computer network, Bus network, Star network, Ring network, Mesh network, etc.). Solutions of Computer and Networks Area from ConceptDraw Solution Park contain powerful drawing tools for easy designing diagrams for any Computer Network from listed diversity.

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. Web based diagrams software can be powerful, but sometimes it is essential to have desktop software. One of the most advanced diagrams tools like Visio for Mac OS is ConceptDraw DIAGRAM app.

Design Element: Computer and Network for Network Diagrams

There are many types of computer networks, they differ in size, topology, organizational intents, in transmission medium used to carry the signals, in communication protocols to organize network traffic, and in many other parameters. Computer Network Diagrams help to visualize schematically computer networks and computer network topologies, equipment nodes, as well as different types of their logical and physical connections. ConceptDraw DIAGRAM is a perfect network diagramming software intended for network designers and software developers who need to draw different types of Computer Network Diagrams. Computer Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park provides for ConceptDraw DIAGRAM users a lot of computer network design elements helpful for visualization varied ideas regarding to design and implementation of computer and telecommunication networks, LAN, MAN and WAN architectures, physical and logical topologies, wiring schematics and cabling layout plans.

Hybrid Network Topology

A network topology is the topological structure or the arrangement of different elements of computer network. There are several basic types of network topologies, such as star, ring, bus, mesh. But the most popular is a combination of two or more diverse basic network topologies, which is known as hybrid network topology. The examples of hybrid topology are: star-bus, star-ring topologies, etc. Each resulting hybrid topology has its own features, advantages and limitations of its components. Hybrid network topologies are more flexible, reliable, and have increased fault tolerance, the faults in them can be easily diagnosed and corrected, new nodes can be easily added. But at the same time hybrid topologies often are sufficiently expensive and difficult for managing. ConceptDraw DIAGRAM diagramming and vector drawing software supplied with the tools of Computer Network Diagrams solution from Computer and Networks area is perfect for schematic description various types of computer network topologies and easy designing Hybrid network topology diagrams.

Metropolitan area networks (MAN). Computer and Network Examples

A Metropolitan Area Network (MAN) is a great computer network located on the large geographical area or region. It is a network bigger than Local Area Network (LAN), but territorially smaller than Wide Area Network (WAN), its diameter usually ranges from 5 to 50 kilometers. MAN usually includes several buildings or even the whole city (metropolis). It is based on high data rate compounds using the fiber channels and other digital data transmission channels. MAN includes a lot of communicating devices, for its construction are used multiple routers, switches and hubs. MAN can combine together several Local Area Networks or Campus Area Networks located in different buildings within a city and provides the Internet connectivity for them. Solutions included to Computer and Networks Area for ConceptDraw Solution Park are the real godsend for those who want design Computer Network Diagrams, and among others the Metropolitan Area Network Diagrams. They offer the libraries with ready-to-use vector design elements, professional-looking examples, samples and templates.

Cisco Network Design. Cisco icons, shapes, stencils, symbols and design elements

Cisco is the largest company, which specializes in the field of high technologies, develops and sells network equipment mainly for the large organizations and telecommunication companies. Cisco produces wide variety of devices and equipment, such as routers, switches, gateways, servers, network security devices (firewalls, VPN, IDs, etc.), ATM switches, cable modems and DSL equipment, access points Wi-Fi, products for IP telephony, etc. The first commercially successful multi-protocol router, which enabled for previously incompatible computers to communicate between themselves, is also developed by Cisco company. Cisco is a generally accepted standard, which uses globally recognized Cisco icons for all produced Cisco equipment. ConceptDraw DIAGRAM software extended with Cisco Network Diagrams solution from Computer and Network area contains a lot of predesigned Cisco network design elements for professional drawing Cisco network diagrams, visualization computer network topologies, equipment connections and arrangement.
