A Technical Assurance Center, or TAC, is a department within a company that's primary purpose is networking, or an ISP. The TAC also works closely with a company's Network Operations Center, or NOC. A TAC can only monitor items with a return signal, such as a modem or a MTA. Forward-only systems, such as cable boxes, are currently unable to be monitored.

Development aid or development cooperation (also development assistance, technical assistance, international aid, overseas aid, official development assistance (ODA), or foreign aid) is financial aid given by governments and other agencies to support the economic, environmental, social and political development of developing countries. It is distinguished from humanitarian aid by focusing on alleviating poverty in the long term, rather than a short term response. The term development cooperation, which is used, for example, by the World Health Organisation (WHO) is used to express the idea that a partnership should exist between donor and recipient, rather than the traditional situation in which the relationship was dominated by the wealth and specialised knowledge of one side. Most development aid comes from the Western industrialised countries but some poorer countries also contribute aid. Aid may be bilateral: given from one country directly to another; or it may be multilateral: given by the donor country to an international organisation such as the World Bank or the United Nations Agencies (UNDP, UNICEF, UNAIDS, etc.) which then distributes it among the developing countries. The proportion is currently about 70% bilateral 30% multilateral.
