Metropolitan area networks (MAN). Computer and Network Examples
A Metropolitan Area Network (MAN) is a large computer network on the large geographical area that include several buildings or even the entire city (metropolis). The geographical area of the MAN is larger than LAN, but smaller than WAN. MAN includes many communicating devices and provides the Internet connectivity for the LANs in the metropolitan area.
MAN is used to combine into a network group located in different buildings into a single network. The diameter of such a network can range from 5 to 50 kilometers. As a rule, MAN does not belong to any particular organization, in most cases, a group of users or a provider who takes charge for the service own its connecting elements and other equipment. Level of service is agreed in advance and some warranties are discussed. MAN often acts as a high-speed network to allow sharing regional resources (like a big LAN). It is also often used to provide public available connection to other networks using a WAN connection. There are many ways of classifying networks. The main criterion for classification is considering the administration method. That is, depending on how the network is organized and how it is controlled, it can be attributed to local or distributed, metropolitan or WAN. or her A network administrator manages a network or it’s segment. Administration team activities are logged, and their rights and responsibilities are strictly divided if the network is complex. Computers can be connected using a variety of media access controllers: a twisted pair, optical conductors (optical cables) and via radio (wireless technology). Wired optical connections are usually established via Ethernet, wireless - through Wi-Fi, Bluetooth, GPRS and other protocols. Private LAN may be linked to other local area networks through gateways, as well as being part of a global computer network (eg, the Internet), or have a connection to it.
Computer and Networks Area for ConceptDraw DIAGRAM provides professional looking examples, the libraries with ready-to-use predesigned vector stencils to help you create anyone computer network diagrams quick, easy and effective.

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity.
This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.

A complete (fully connected) topology is a network topology in which there is a direct link between all pairs of nodes. In a fully connected network with n nodes, there are n(n-1)/2 direct links. Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the multiple paths for data that are provided by the large number of redundant links between nodes.

Hazard pictograms are those which form a part of the international GHS which is a “Globally Harmonized System of Classification and Labelling of Chemicals. Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods. Either one or the other is chosen, depending on the target audience, but the two are not used together.

Flowcharts can be used in designing and documenting both simple and complex processes or programs and, similar to the other types of diagrams, they can help visualize what happens and so help understand some definite process, and, as a result, find flaws, bottlenecks and other features within it.

There are many ways to describe a database structure. One of the most usual is to draw an entity relationship diagram (ERD) using a Crow’s Foot notation to represent database elements. If you don’t want to draw it on paper, you should use an appropriate software.
An entity-relationship (ER) diagram is used to show the structure of a business database. ERD represents data as objects (entities) that are connected with standard relationships symbols which Illustrate an association between entities. ERD, there is a wide range of ERD notations used by data bases architects for reflecting the relationships between the data entities. According to the crow’s foot notation relationships are drawn as single labeled lines designating a certain kinds of relationship. Crow foot notation is a most frequently used ERD standard, because of improved readability of diagrams, with a more accurate use of space on the page.
