  2. Qualcomm EDL mode - Wikipedia

    en.wikipedia.org/wiki/Qualcomm_EDL_mode

    Screenshot of Device Manager, containing a Qualcomm device booted in the Emergency Download Mode. The Qualcomm Emergency Download mode, commonly known as Qualcomm EDL mode and officially known as Qualcomm HS-USB QD-Loader 9008 [1] is a feature implemented in the boot ROM of a system on a chip by Qualcomm which can be used to recover bricked smartphones.

  3. Merkle tree - Wikipedia

    en.wikipedia.org/wiki/Merkle_tree

    In cryptography and computer science, a hash tree or Merkle tree is a tree in which every "leaf" node is labelled with the cryptographic hash of a data block, and every node that is not a leaf (called a branch, inner node, or inode) is labelled with the cryptographic hash of the labels of its child nodes.

  4. 2 nm process nodes - Wikipedia

    en.wikipedia.org/wiki/2_nm_process

    In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.

  5. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter , but such systems are expensive and generally used only in ...

  6. Bit error rate - Wikipedia

    en.wikipedia.org/wiki/Bit_error_rate

    It will not invoke a B8ZS sequence because eight consecutive zeros are required to cause a B8ZS substitution. The pattern is effective in finding equipment misoptioned for B8ZS. Bridgetap - Bridge taps within a span can be detected by employing a number of test patterns with a variety of ones and zeros densities. This test generates 21 test ...

  7. 7 nm process - Wikipedia

    en.wikipedia.org/wiki/7_nm_process

    The naming of process nodes by 4 different manufacturers (TSMC, Samsung, SMIC, Intel) is partially marketing-driven and not directly related to any measurable distance on a chip – for example TSMC's "7nm" node was previously similar in some key dimensions to Intel's planned first-iteration "10nm" node, before Intel released further iterations ...

  8. 90 nm process - Wikipedia

    en.wikipedia.org/wiki/90_nm_process

    Toshiba, Sony and Samsung developed a 90 nm process during 2001–2002, before being introduced in 2002 for Toshiba's eDRAM and Samsung's 2 Gb NAND flash memory. [7] [8] IBM demonstrated a 90 nm silicon-on-insulator (SOI) CMOS process, with development led by Shahidi, in 2002. The same year, Intel demonstrated a 90 nm strained-silicon process. [9]

  9. Time to live - Wikipedia

    en.wikipedia.org/wiki/Time_to_live

    The original DARPA Internet Protocol's RFC describes [1]: §1.4 TTL as: . The Time to Live is an indication of an upper bound on the lifetime of an internet datagram.It is set by the sender of the datagram and reduced at the points along the route where it is processed.
