IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
A PAN may be carried over wired interfaces such as USB, but is predominantly carried wirelessly, also called a wireless personal area network (WPAN). A PAN is wirelessly carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth, NearLink or Zigbee. The reach of a WPAN varies from a few ...
A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, [ 1 ] [ 2 ] [ 3 ] for sharing data and devices between each other, including Internet access .
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.
A MAN is a means for sharing resources at high speeds within the network. It often provides connections to WAN networks for access to resources outside the scope of the MAN. [2] Data center networks also rely highly on TCP/IP for communication across machines. They connect thousands of servers, are designed to be highly robust, provide low ...
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
