  2. Local area network - Wikipedia

    en.wikipedia.org/wiki/Local_area_network

    A router is configured with the provider's IP address on the WAN interface, which is shared among all devices in the LAN by network address translation. A gateway establishes physical and data link layer connectivity to a WAN over a service provider's native telecommunications infrastructure.

  3. Wide area network - Wikipedia

    en.wikipedia.org/wiki/Wide_area_network

    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.

  4. Ethernet - Wikipedia

    en.wikipedia.org/wiki/Ethernet

    Ethernet (/ ˈ iː θ ər n ɛ t / EE-thər-net) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). [1] It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.

  5. IEEE 802.3 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.3

    IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).

  6. Port (computer networking) - Wikipedia

    en.wikipedia.org/wiki/Port_(computer_networking)

    In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.

  7. List of TCP and UDP port numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_TCP_and_UDP_port...

    The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...

  8. 10 Gigabit Ethernet - Wikipedia

    en.wikipedia.org/wiki/10_Gigabit_Ethernet

    The WAN PHY was designed to interoperate with OC-192/STM-64 SDH/SONET equipment using a light-weight SDH/SONET frame running at 9.953 Gbit/s. The WAN PHY operates at a slightly slower data-rate than the local area network (LAN) PHY. The WAN PHY can drive maximum link distances up to 80 km depending on the fiber standard employed.

  9. Home network - Wikipedia

    en.wikipedia.org/wiki/Home_network

    For example the fact a typical home router has 4 to 6 Ethernet LAN ports, so a router's switching capacity could be exceeded. Another example may be that a network device might require a non-standard port feature such as power over Ethernet (PoE). (IP cameras and IP phones).
