Problem: USB:

USB device communication is based on pipes (logical channels). A pipe is a connection from the host controller to a logical entity, found on a device, and named an endpoint. Because pipes correspond 1-to-1 to endpoints, the terms are sometimes used interchangeably. A USB device could have up to 32 endpoints (16 IN, 16 OUT), though it's rare to have so many. An endpoint is defined and numbered by the device during initialization (the period after physical connection called "enumeration") and so is relatively permanent, whereas a pipe may be opened and closed.

What is a pipe?

A: a connection from the host controller to a logical entity

Problem: The developments during World War II continued for a short time into the post-war period as well. In particular the U.S. Army set up a huge air defence network around its larger cities based on radar-guided 90 mm and 120 mm guns. US efforts continued into the 1950s with the 75 mm Skysweeper system, an almost fully automated system including the radar, computers, power, and auto-loading gun on a single powered platform. The Skysweeper replaced all smaller guns then in use in the Army, notably the 40 mm Bofors. In Europe NATO's Allied Command Europe developed an integrated air defence system, NATO Air Defence Ground Environment (NADGE), that later became the NATO Integrated Air Defence System.
Which military set up a large air defence network surrounding its larger cities?

Context and question: The word qur'an appears about 70 times in the Quran itself, assuming various meanings. It is a verbal noun (masdar) of the Arabic verb qara'a (), meaning "he read" or "he recited". The Syriac equivalent is () qeryana, which refers to "scripture reading" or "lesson". While some Western scholars consider the word to be derived from the Syriac, the majority of Muslim authorities hold the origin of the word is qara'a itself. Regardless, it had become an Arabic term by Muhammad's lifetime. An important meaning of the word is the "act of reciting", as reflected in an early Quranic passage: "It is for Us to collect it and to recite it (qur'anahu)."
Which word do most Muslim scholars point to as the origin of the Quran's name?

Problem: Norfolk Island:

It was announced on 19 March 2015 that self-governance for the island would be revoked by the Commonwealth and replaced by a local council with the state of New South Wales providing services to the island. A reason given was that the island had never gained self-sufficiency and was being heavily subsidised by the Commonwealth, by $12.5 million in 2015 alone. It meant that residents would have to start paying Australian income tax, but they would also be covered by Australian welfare schemes such as Centrelink and Medicare.

When did the Commonwealth of Australia announce that Norfolk Island would always be governed by itself?
