QUES: In 1994, over a hundred intrusions were made by unidentified crackers into the Rome Laboratory, the US Air Force's main command and research facility. Using trojan horses, hackers were able to obtain unrestricted access to Rome's networking systems and remove traces of their activities. The intruders were able to obtain classified files, such as air tasking order systems data and furthermore able to penetrate connected networks of National Aeronautics and Space Administration's Goddard Space Flight Center, Wright-Patterson Air Force Base, some Defense contractors, and other private sector organizations, by posing as a trusted Rome center user.

How were hackers able to obtain unrestricted access to Rome's networking systems?
What is the answer?
ANS: Using trojan horses
QUES: Because the electron mobility is higher than the hole mobility for all semiconductor materials, a given bipolar npn transistor tends to be swifter than an equivalent pnp transistor. GaAs has the highest electron mobility of the three semiconductors. It is for this reason that GaAs is used in high-frequency applications. A relatively recent FET development, the high-electron-mobility transistor (HEMT), has a heterostructure (junction between different semiconductor materials) of aluminium gallium arsenide (AlGaAs)-gallium arsenide (GaAs) which has twice the electron mobility of a GaAs-metal barrier junction. Because of their high speed and low noise, HEMTs are used in satellite receivers working at frequencies around 12 GHz. HEMTs based on gallium nitride and aluminium gallium nitride (AlGaN/GaN HEMTs) provide a still higher electron mobility and are being developed for various applications.

Which material has the highest electron mobility?
What is the answer?
ANS: unanswerable
QUES: Bateman was responsible for the building of 36 new buildings for the university both on and off campus, including the expansion of the Harold B. Lee Library. He was also one of several key college leaders who brought about the creation of the Mountain West Conference, which BYU's athletics program joined BYU previously participated in the Western Athletic Conference. A BYU satellite TV network also opened in 2000 under his leadership. Bateman was also president during the September 11th attacks in 2001. The planes crashed on a Tuesday, hours before the weekly devotional normally held at BYU. Previous plans for the devotional were altered, as Bateman led the student body in a prayer for peace. Bateman was followed by Cecil O. Samuelson in 2003. Samuelson was succeeded by Kevin J Worthen in 2014.

What type of BYU TV network opened in 2000 under Pres. Merrill J. Bateman?
What is the answer?
ANS:
satellite
