Disadvantages Of LAN- LANcovers small geographical area. Security issues are big concern as it is easy to have access to programs and data of peers. Special security measures are needed to stop unauthorized access. Title: Limitations, Pros and Cons of LAN, MAN, WAN Description: This is a PDF file of a presentation about the limitations, advantages and disadvantages of different types of networks. There are many advantages of LAN over MAN and WAN, such as LAN’s provide excellent reliability, high data transmission rate, they can easily be managed, and shares peripheral devices too. Local Area Network cannot cover cities or towns and for that Metropolitan Area Network is needed, which can connect city or a group of cities together. MAN is the abbreviation for Metropolitan Area Network and bigger than LAN network. It connects computer users that are in a specific geographical area. An example of MAN is your cable television or a large university. MAN’s data transmission speed is 5-10Mbps, which is faster and more expensive than LAN but slower and smaller than WAN. In general a LAN connection will be the fastest as the data does have to travel so far, and the costs of setting it up are relatively low. A MAN would probably be the next fastest as the data is only travelling around the city. WAN Networks are probably the slowest as the traffic could be traveling all around the world.Metropolitan Area Network
A metropolitan area network (MAN) is a network with a size between a LAN and a WAN. It normally covers the area inside a town or a city. It is designed for customers who need a high-speed connectivity, normally to the internet, and have endpoints spread over a city or part of city. A good example of a MAN is part of the telephone company network that can provide a high-speed DSL line to the customer.
A MAN may be wholly owned and operated by a private company, or it may be a service provided by a public company, such as a local telephone company. Many telephone companies vide a popular MAN service called Switched Multi-megabit Data Services (SMDS).
Advantages And Disadvantages Of Lan Wan And Man Relationship
advantages of MAN
– It utilizes drawbacks of both LAN and WAN to provide larger and controllable computer network.
– MAN requires fewer resources compare to WAN. This saves the implementation cost.
– It helps people interface fast LANs together. This is due to easy implementation of links.
– It provides higher security compare to WAN.
– It helps in cost effective sharing of common resources such as printers etc.
– Like LAN and WAN, it also offers centralized management of data and files.

– It is difficult to manage the network once it becomes large.
– It is difficult to make the system secure from hackers and industrial espionage.
– Network installation requires skilled technicians and network administrators. This increases overall installation and management costs.
– It requires more cables for connection from one place to the other compare to LAN.
