QUES: The design architecture of USB is asymmetrical in its topology, consisting of a host, a multitude of downstream USB ports, and multiple peripheral devices connected in a tiered-star topology. Additional USB hubs may be included in the tiers, allowing branching into a tree structure with up to five tier levels. A USB host may implement multiple host controllers and each host controller may provide one or more USB ports. Up to 127 devices, including hub devices if present, may be connected to a single host controller. USB devices are linked in series through hubs. One hubbuilt into the host controlleris the root hub.

How many devices may be connected to a host controller?
What is the answer?
ANS: 127 devices
QUES: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.

What is the result of using DC power on a DC motor?
What is the answer?
ANS: unanswerable
QUES: Orthodox Christianity includes a large number of traditions regarding the Ever Virgin Mary, the Theotokos. The Orthodox believe that she was and remained a virgin before and after Christ's birth. The Theotokia (i.e., hymns to the Theotokos) are an essential part of the Divine Services in the Eastern Church and their positioning within the liturgical sequence effectively places the Theotokos in the most prominent place after Christ. Within the Orthodox tradition, the order of the saints begins with: The Theotokos, Angels, Prophets, Apostles, Fathers, Martyrs, etc. giving the Virgin Mary precedence over the angels. She is also proclaimed as the "Lady of the Angels".

What are hymns to the Theotokos called in Orthodox tradition?
What is the answer?
ANS:
The Theotokia
