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.

A circuit diagram is sometimes also called an elementary diagram, electronic schematic or electrical diagram circuits. It is essential in construction of any electronic equipment. Among many digital drawing tools available, ConceptDraw DIAGRAM is a leading circuits and logic diagram software, affording for easy and quick creation of even the most advanced and complex diagram designs. This makes it a perfect choice for computer science and any kind of electronic engineering.
This drawing includes the graphic symbols that may be in use while creating a logic circuit diagram. The diagrams of such kind are used in the electronics industry. The logic symbol depicts a device that realizes a Boolean type functions. Practically a logic symbol means transistor, diodes, relays, and other mechanical or optical details which provide function of closing or opening "gates". Totally the logic circuits can involve millions of gates. ConceptDraw Electrical Engineering solution gives the opportunity to create a circuit diagrams both simple and difficult.

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical.
This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.

A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks.
Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.Picture: Metropolitan area networks (MAN).

Network infrastructure planning is a very important process in the network construction, and the share of time allocated to this within the scope of the entire project may reach 60-80%. A competent and thorough approach to planning contributes to the quick investment return, and also increases the reliability and flexibility of the final system, reducing the probability of additional costs related to the incorrect implementation.
Any planning begins with an analysis of the business requirements to the final system. Basic network parameters, which should be assessed are the scalability, accessibility, cost, speed and safety.
Speed and cost are often mistaken for the most important parameters, and the rest of the parameters aren't even remembered. This is not entirely correct. Initially, it is necessary to assess the business plans for the future, because sometimes it is more profitable to invest more money in the beginning. If the business is to develop, then, consequently, demands on
