What is MAN?
MAN - Metropolitan Area Networks.
MAN is bigger than a LAN and as its name implies, covers the area of a single city. MANs rarely extend beyond 100 KM and frequently comprise a combination of dissimilar hardware and transmission media.
The two most significant components of MANs are security and standardization. Security is vital because information is being shared among dissimilar systems. Standardization is essential to ensure reliable data communication
