Question: The MC controls the conferencing while it is active on the signaling plane, which is simply where the system manages conferencing creation, endpoint signaling and in-conferencing controls. This component negotiates parameters with every endpoint in the network and controls conferencing resources. While the MC controls resources and signaling negotiations, the MP operates on the media plane and receives media from each endpoint. The MP generates output streams from each endpoint and redirects the information to other endpoints in the conference.
Is there an answer to this question: What is one example of what the signaling plane controls in a videoconferencing system?

Answer: endpoint signaling


Question: One of Albert's greatest contributions was his study of Dionysus the Areopagite, a mystical theologian whose words left an indelible imprint in the medieval period. Magnus' writings made a significant contribution to German mysticism, which became vibrant in the minds of the Beguines and women such as Hildegard of Bingen and Mechthild of Magdeburg. Mysticism, for the purposes of this study, refers to the conviction that all believers have the capability to experience God's love. This love may manifest itself through brief ecstatic experiences, such that one may be engulfed by God and gain an immediate knowledge of Him, which is unknowable through the intellect alone.
Is there an answer to this question: What was not one of Albert's great contributions?

Answer: unanswerable


Question: The nonprofit landscape is highly varied, although many people have come to associate NPOs with charitable organizations. Although charities do comprise an often high profile or visible aspect of the sector, there are many other types of nonprofits. Overall, they tend to be either member-serving or community-serving. Member-serving organizations include mutual societies, cooperatives, trade unions, credit unions, industry associations, sports clubs, retired serviceman's clubs and peak bodies – organizations that benefit a particular group of people i.e. the members of the organization. Typically, community-serving organizations are focused on providing services to the community in general, either globally or locally: organizations delivering human services programs or projects, aid and development programs, medical research, education and health services, and so on. It could be argued many nonprofits sit across both camps, at least in terms of the impact they make. For example, the grassroots support group that provides a lifeline to those with a particular condition or disease could be deemed to be serving both its members (by directly supporting them) and the broader community (through the provision of a helping service for fellow citizens).
Is there an answer to this question: Who does an NPO usually serve?

Answer: member-serving or community-serving
