Problem: In addition to and independent of the division into suras, there are various ways of dividing the Quran into parts of approximately equal length for convenience in reading. The 30 juz' (plural ajzāʼ) can be used to read through the entire Quran in a month. Some of these parts are known by names—which are the first few words by which the juzʼ starts. A juz' is sometimes further divided into two ḥizb (plural aḥzāb), and each hizb subdivided into four rubʻ al-ahzab. The Quran is also divided into seven approximately equal parts, manzil (plural manāzil), for it to be recited in a week.
How many ahzab are in a juz'?

Problem: A videoconference system is generally higher cost than a videophone and deploys greater capabilities. A videoconference (also known as a videoteleconference) allows two or more locations to communicate via live, simultaneous two-way video and audio transmissions. This is often accomplished by the use of a multipoint control unit (a centralized distribution and call management system) or by a similar non-centralized multipoint capability embedded in each videoconferencing unit. Again, technology improvements have circumvented traditional definitions by allowing multiple party videoconferencing via web-based applications.
What is a multi-point control unit?
