We see how a MAN network quickly connects several buildings with a LAN network, located between them at a considerable distance. It connects them so well that it seems they are on a LAN even though they are more than 50 km away. distance between them.
For those who know English and do not know much about computers, the MAN network concept may sound something like "red man". Returning to our "network" refers to a normal network of type like internet, "MAN" is an English acronym that means "Metropolitan Area Network". Thus, we have as a literal meaning, Metropolitan Area Network ”. Once the term is explained, it must be said that its own translation defines it, it is a network in a metropolitan area.
There are many types of MAN networks but the function that these various types perform is essentially to provide an area where many people live and / or work an interconnection so that the inhabitants of that area can share video and voice over a copper cable. or fiber optic. There are other terms like LAN network, translated; local area network, as well as translated WAN network; wide-range network, the MAN network differs from the other two mentioned (LAN and WAN) in that its maintenance is considerably less expensive and that you can always predict how many people will connect to the network simultaneously, not accurately predict but Yes, with very little margin of error, it is for this reason that when we are on vacation in an area, sometimes the network of the resting place drops because more people suddenly connect than the network supports and it becomes "stuck" due to say it somehow.
MAN networks are based on the IEEE standard (Institute of Electrical and Electronics Engineers) translated as Institute of Electrical and Electronic Engineers. This standard gives the network reliability, stability, security, as well as other favorable qualities that contribute to lower maintenance costs. A MAN network can be made up of a few LAN networks or even many LAN networks, it can be made up and include within its structure other smaller networks etc., the combinations are many.
A graphical representation of the different major networks that exist.
MAN networks can have many applications, such as video surveillance, WIFI zones in addition to the typical internet connection and many other applications that we will not discuss. They can be public or private, the private ones are the well-known as internet providers for example and the public ones are those that connect a whole series of public buildings to a central database to coordinate, for example, the census of workers who contribute to social security.
