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 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.

Network Community Structure. Computer and Network Examples

Network community structure is a network which nodes can be easily grouped into the sets of nodes with dense internally connections. This example shows a network that displays the community structure with three groups of nodes with dense internal connections and sparser connections between the groups.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.

Activity Network Diagram Method

Activity Network Diagram - This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Seven Management and Planning Tools solution from the Management area of ConceptDraw Solution Park. This sample shows the PERT (Program Evaluation Review Technique) chart of the request on proposal. A request for proposal (RFP) is a request of the company or the organization to potential suppliers to submit the business proposals for service or goods that it is interested to purchase. The RFP is represented on the initial procurement stage and allows to define the risks and benefits.

Example of DFD for Online Store (Data Flow Diagram)

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw DIAGRAM enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols.

Computer Networking Tools List

Network Diagrams visualize schematically the computer networks topology, equipment nodes and different types of their logical and physical connections. They are widely used by IT professionals to visually document the topology and design of computer and telecommunication networks.

Storage area networks (SAN). Computer and Network Examples

A Storage area network (SAN) is a dedicated network that provides access to data storage and operations only on the block level. SAN usually has own network of storage devices/elements and disk arrays that are connected with each other and to a remote data-sharing network. SANs are widely used for enhancing the storage devices (optical jukeboxes, disk arrays, tape libraries) that are accessible for networked servers. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park. It shows the hybrid of Storage area network (SAN) and Network Attached Storage (NAS) technologies.

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.
