Advantages of MAN | disadvantages of MAN
This page covers advantages and disadvantages of MAN. It mentions MAN advantages or benefits and MAN disadvantages or drawbacks. MAN stands for Metropolitan Area Network.
What is MAN?
It interconnects number of LANs using high capacity backbone technology. It is a large network which usually spans city or large campus. It's geographic coverage is in between LAN and WAN.
Following are the types of MAN.
• Asynchronous Transfer Mode (ATM)
• Fiber Distribution Data Interface (FDDI)
• Switched multi megabit data service (SMDS)
Based on distance covered, the computer networks are divided into three main parts viz. LAN, MAN and WAN. Among these types, MAN has medium coverage which is in between LAN and WAN. It supports distances upto 100 miles (or 200 km) and data rates of about 100 Mbps. Refer difference between LAN vs WAN vs MAN>>.
Benefits or advantages of MAN
Following are the benefits or 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.
Drawbacks or disadvantages of MAN
Following are the disadvantages of MAN:
➨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.
