Wide area network (WAN) topology. 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.

Entity Relationship Diagram Symbols

The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style. The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software.

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.

Point to Point Network Topology

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park. This sample shows the Point-to-point network topology. Network topology is the topological structure of the computer network. Point-to-point network topology is a simple topology that displays the network of exactly two hosts (computers, servers, switches or routers) connected with a cable. Point-to-point topology is widely used in the computer networking and computer architecture.

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.

Design elements - Cisco routers

The vector stencils library "Cisco routers" contains 27 router symbols for drawing the Cisco computer network diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node.
The most familiar type of routers are home and small office routers that simply pass data, such as web pages, email, IM, and videos between the home computers and the Internet. An example of a router would be the owner's cable or DSL modem, which connects to the Internet through an ISP. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common." [Router (computing). Wikipedia]
The example "Design elements - Cisco routers" is included in the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

Telecommunication networks - Vector stencils library

The vector stencils library "Telecommunication networks" contains 32 clipart images of telecommunication network devices and equipment for drawing telecom network diagrams.
"A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals.
The transmission links connect the nodes together. The nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal.
Each terminal in the network usually has a unique address so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space." [Telecommunications network. Wikipedia]
The clip art example "Telecommunication networks - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Telecommunication Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
