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.

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.

ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.

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.

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.
