Its mission is to prevent work-related injuries, illnesses, and occupational fatality by issuing and enforcing standards for workplace safety and health. The agency is headed by a Deputy Assistant Secretary of Labor. OSHA issues guidelines and regulations for the safe use of a computer.
Answer option B is incorrect. The Federal Bureau of Investigation (FBI) is an agency of the United States Department of Justice that serves as both a federal criminal investigative body and an internal intelligence agency. The FBI has investigative jurisdiction over violations of more than 200 categories of federal crime. Its motto is "Fidelity, Bravery, Integrity", corresponding to the FBI initials.The FBI's top investigative priorities are as follows:

Protect the United States from a terrorist attack.
Protect the United States against foreign intelligence operations and espionage. Protect the United States against cyber-based attacks and high-technology crimes, such as Cyberwarfare, Cyberstalking, Cyberfraud,
Cybertheft, etc.
Combat transnational/national criminal organizations and enterprises. Upgrade technology for successful performance of the FBI's mission.

Answer option D is incorrect. The Institute of Electrical and Electronic Engineers (IEEE) is a society of technical professionals. It promotes the development and application of electro-technology and allied sciences. IEEE develops communications and network standards, among other activities. The organization publishes number of journals, has many local chapters, and societies in specialized areas.
Answer option C is incorrect. The International Organization for Standardization, widely known as ISO, is an international-standard-setting body composed of representatives from various national standards organizations. Founded on 23 February 1947, the organization promulgates worldwide proprietary industrial and commercial standards. It has its headquarters in Geneva, Switzerland.
While ISO defines itself as a non-governmental organization, its ability to set standards that often become law, either through treaties or national standards, makes it more powerful than most non-governmental organizations. In practice, ISO acts as a consortium with strong links to governments.

QUESTION: 22

Drag and drop the connector names below their respective connectors as shown in the image.

See Explanation section for answer.

Answer(s): A

Explanation:

The image displays the following connectors:RP-TNC connector: An RP-TNC (Reverse-Polarity- Threaded Neil Concelman) is a variation of the TNC specification that reverses the polarity of the interface. This is usually achieved by incorporating the female contacts normally found in jacks into the plug, and the male contacts normally found in plugs into the jack. RP-TNC connectors are widely used by Wi-Fi equipment manufacturers to comply with specific local regulations, i.e. those from the FCC, which are designed to prevent consumers from connecting antennas that exhibit gain and therefore breach compliance. RP-TNC can also be abbreviated as RTNC.

N connector: An N connector is a threaded RF connector that is used to join coaxial cables. It is the first connector capable of carrying microwave signals. This connector initially carried signals of up to 1 GHz for military applications when it was designed, but the common N type connector, which is used today, carries signals of up to 11 GHz easily. It follows the MIL-C-39012 standard.

SMA connector: An SMA (Subminiature version A) connector is a coaxial RF connector designed in the 1960s. It is designed as a minimal connector interface for coaxial cable that follows the screw type coupling mechanism. The impedance of an SMA connector is 50 O. It provides an outstanding electrical performance from DC to 18 GHz.
