    en.wikipedia.org/wiki/Year_2038_problem

    The year 2038 problem (also known as Y2038, [1] Y2K38, Y2K38 superbug or the Epochalypse [2] [3]) is a time computing problem that leaves some computer systems unable to represent times after 03:14:07 UTC on 19 January 2038. The problem exists in systems which measure Unix time —the number of seconds elapsed since the Unix epoch (00:00:00 UTC ...

    Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks ( WLANs ). It operates in the 2.4 GHz and 5 GHz bands, [9] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [10] It is an upgrade from Wi-Fi 5 ( 802.11ac ), with improvements for better performance in crowded places.

    en.wikipedia.org/wiki/Ethernet_flow_control

    Ethernet flow control. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion . The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.

  7. Media-independent interface - Wikipedia

    en.wikipedia.org/wiki/Media-independent_interface

    The serial gigabit media-independent interface (SGMII) is a variant of MII used for Gigabit Ethernet but can also carry 10/100 Mbit/s Ethernet. It uses differential pairs at 625 MHz clock frequency DDR for TX and RX data and TX and RX clocks. It differs from GMII by its low-power and low pin-count 8b/10b -coded SerDes.

  8. EtherType - Wikipedia

    en.wikipedia.org/wiki/EtherType

    EtherType is a two- octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames. EtherType is also used as the basis ...
