4.1.4 Metropolitan Area Networks MAN:
This network extends across an entire city (such as the network of the administrative
capital or an integrated compound). The MAN network is highly efficient, providing
fast connectivity through high-speed carriers like optical fiber cables. It is ideal for
various types of network users due to its medium size and is used to build high-speed
networks for modern cities.

4.1.5 Wide Area Networks WAN:
It is the connection between multiple local networks located in separate geographical
locations, such as networks connecting branches of a single bank at the national level.
WANs can extend to cities, countries, or even continents through
telecommunications service providers or satellite communication.
