    en.wikipedia.org/wiki/Syn_and_anti_addition

    In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.

  4. Transmission Control Protocol - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Protocol

    TCP Fast Open allows the transmission of data in the initial (i.e., SYN and SYN-ACK) packets, removing one RTT of latency during connection establishment. [116] However, TCP Fast Open has been difficult to deploy due to protocol ossification; as of 2020, no Web browsers used it by default. [103] TCP throughput is affected by packet reordering ...

    en.wikipedia.org/wiki/TCP_hole_punching

    SYN from Peer A reaches NAT-b, SYN from Peer B reaches NAT-a; Depending on the timing of these events (where in the network the SYN cross), at least one of the NAT will let the incoming SYN through, and map it to the internal destination peer; Upon receipt of the SYN, the peer sends a SYN+ACK back and the connection is established.

    SYN cookie is a technique used to resist SYN flood attacks. The technique's primary inventor Daniel J. Bernstein defines SYN cookies as "particular choices of initial TCP sequence numbers by TCP servers." In particular, the use of SYN cookies allows a server to avoid dropping connections when the SYN queue fills up.

  9. C0 and C1 control codes - Wikipedia

    en.wikipedia.org/wiki/C0_and_C1_control_codes

    In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
