communication protocols - 2025 PACE NSC

Question

They're not databases, but "federated" examples of these systems include ActivityPub and the subject of the non-meteorological ATmosphere Conference. "Wars" (0[1])over these systems were lost by (0[1])X.25 and the OSI model following Van Jacobson's development of a congestion control algorithm for one of these systems. One of these systems has a "loopback" value for self-reference that begins (*) "127." (10[3])To avoid "exhaustion" (10[1])of four-number (10[1])dot-decimal notation (10[1])values, (10[3]0[1])the "v4" (10[1]0[1])of one (10[2])of these systems (10[5])has been partially (0[1])supplanted (10[2])by (10[1])"v6". (10[2]0[2])A "secure" (10[1])extension to one of these systems (0[1])adds "S" (0[1])to a (10[2])four-letter (10[1])acronym (10[1])that appears (10[1])in web addresses. (10[2])For 10 points, name these network communication systems denoted by the "P" in "HTTP." (10[2]0[1])■END■ (10[6]0[3])

ANSWER: communication protocols [or transfer protocols or Internet protocols; accept Internet Protocol suite or Transmission Control Protocol or Hypertext Transfer Protocol Secure; accept IPs or IPv4 or IPv6 or IP addresses; accept TCP/IP; accept HTTPS before read; prompt on computer networks or social networks before "network" is read by asking "what systems facilitate the formation of these networks?"; prompt on addresses before read by asking "what systems provide these addresses?"] (The ATmosphere Conference is dedicated to the AT Protocol.)
