NEW QUESTION # 70
Which motherboard component is used for short-term storage of data?
Answer: C
Explanation:
*RAM (Random Access Memory) is the motherboard component used for short-term storage of data.
*RAM is a type of computer memory that can be read and written. It serves as temporary storage for data that the CPU (Central Processing Unit) needs to access quickly.
*When you run programs or open files, the data is loaded into RAM from storage devices (such as hard drives or SSDs). The CPU can then access this data rapidly, allowing for efficient execution of tasks.
*Unlike permanent storage (such as hard drives), RAM is volatile, meaning its contents are lost when the computer is powered off or restarted.
*RAM is crucial for overall system performance. The more RAM a computer has, the better it can handle multitasking, large applications, and data-intensive tasks.
*In summary, RAM provides fast, temporary storage for data that the CPU actively uses during program execution.

NEW QUESTION # 71
What is the type of software that has no intellectual property protections?
Answer: B
Explanation:
Public domain software has no intellectual property protections such as copyright restrictions. In Information Technology licensing concepts, public domain means the creator has waived copyright or the copyright has expired, so the work can be used freely by anyone. Users can copy, modify, distribute, and reuse the software without needing permission and without paying licensing fees. This is different from freeware, which is free to use but still copyrighted and subject to license limitations. It is also different from shareware, which is typically copyrighted software released as a trial or limited version to encourage purchase of the full product.
Closed-source refers to a model where the source code is not provided publicly, but it does not mean there are no intellectual property protections. The key phrase in the question is no intellectual property protections, which aligns directly with public domain status. Therefore, the correct answer is public domain.
NEW QUESTION # 72
Which of the following is required for communication over the Internet?
Answer: B
Explanation:
Communication over the Internet relies on packet-switched networks. Here's why:
1.Packet Switching:
oThe Internet uses a packet-switching approach to transmit data.
oIn this method, data is divided into smaller packets before transmission.
oEach packet contains a portion of the original data along with addressing information.
oThese packets are then sent independently across the network.
oAt the destination, the packets are reassembled to reconstruct the original data.
2.Advantages of Packet Switching:
oEfficiency: Packet switching allows multiple users to share the same network resources efficiently.
oRobustness: If a link or node fails, packets can find alternative routes to reach their destination.
oScalability: The network can handle varying traffic loads without significant reconfiguration.
3.Other Options:
oAn IP Alias: An IP alias is an additional IP address associated with a network interface. It is not a requirement for communication over the Internet.
oA LAN (Local Area Network): A LAN is a local network within a limited geographical area. While LANs are essential for local communication, they are not directly required for Internet communication.
oA circuit-switched network: Circuit-switched networks establish dedicated connections between sender and receiver. The Internet does not use this approach.
oAn analog signal: Analog signals were used in older communication systems (e.g., telephone lines), but the Internet primarily relies on digital signals.

NEW QUESTION # 73
What is one example of a professional organization in the IT industry?
Answer: A
Explanation:
Computer Professionals for Social Responsibility is an example of a professional organization in the IT industry. Professional organizations are generally membership-based groups that support practitioners through community, publications, conferences, ethical guidance, and advocacy related to professional practice. CPSR historically focused on the social and ethical impacts of computing, encouraging responsible technology use and informed public policy discussion. By contrast, the National Security Agency is a government intelligence and cybersecurity agency, the Institute for Telecommunication Sciences is a U.S. government research organization under the Department of Commerce, and the Federal Communications Commission is a government regulatory body overseeing communications. Those entities may influence IT and telecommunications, but they are not professional membership organizations in the standard sense used in IT fundamentals coursework. Professional organizations often provide networking opportunities, professional development resources, and codes of ethics or best-practice guidance for members. Therefore, among the options given, CPSR is the correct example of a professional organization in the IT industry.
NEW QUESTION # 74
What is a common physical location for data storage that needs to be off-site?
Answer: D
Explanation:
Salt mines are a well-known physical location used for off-site data storage, especially for long-term archival backups. In Information Technology and records management, underground salt mines offer environmental conditions that help preserve storage media. They are typically cool, dry, and stable, which reduces humidity- related damage, corrosion, and temperature fluctuations that can degrade tapes, disks, and other archival media. Their underground location can also provide protection from many surface-level threats such as storms, fires, and some types of physical intrusions. Because off-site storage is meant to protect data from disasters affecting the primary site, a specialized facility like a salt mine can serve as a secure and controlled environment for storing backup media. The other options are not standard "common physical locations" described in many IT disaster recovery materials. Cold or warm climates are vague, and coastlands are generally higher risk due to storms and flooding. Therefore, salt mines are a common physical location used for off-site storage.
