A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area.The term MAN is applied to the interconnection of local area networks (LANs) in a city into a single larger network which may then also offer efficient connection to a wide area network.

The LAN contrasts the wide area network (WAN), which not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links. An even greater contrast is the Internet , which is a system of globally connected business and personal computers.
These acronyms are used to discuss LAN, internet, WAN, routing and switching protocols, and their applicable organizations. [1] [2] [3] The table contains only current, common, non-proprietary initialisms that are specific to information technology. Most of these initialisms appear in IT career certification exams such as CompTIA A+.
Unlike IAN, LAN interconnects computers in a limited area, such as a home, a school, a computer laboratory, or an office building. The WAN also differs from the IAN because it is a network that covers a broad area, such as any telecommunications network that links across metropolitan , regional, or national boundaries, using private or public ...
At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level, individual nodes may represent entire cities. In addition, when the scope of a diagram crosses the common LAN/ MAN /WAN boundaries, representative hypothetical devices may be depicted instead of showing all ...
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [ 3 ] [ 4 ] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association.. It is concerned with: [1] 802 LAN/MAN architecture; internetworking among 802 LANs, MANs and wide area networks
