NEW QUESTION # 25
Which type of network is used to connect wireless headphones to a smartphone?
Answer: B
Explanation:
Wireless headphones typically connect to a smartphone using Bluetooth, which is an example of a personal area network. In Information Technology, a personal area network is a short-range network centered around an individual's devices, usually within a few meters. PAN technology is designed for low power usage and convenient device pairing, making it ideal for accessories such as headphones, smartwatches, fitness trackers, and wireless keyboards. A local area network covers a larger area such as a home, office, or campus and commonly uses Ethernet or Wi-Fi to connect computers and network devices. A wide area network spans large geographic distances and connects networks across cities, countries, or continents, often using leased lines or internet infrastructure. Extended area network is not a standard category used in most networking fundamentals curricula compared with PAN, LAN, MAN, and WAN. Since the connection between headphones and a phone is short-range and personal, it is best classified as a personal area network.
Therefore, the correct answer is PAN.
NEW QUESTION # 26
Which generation of computing is known for the use of operating systems to allow for shared memory and resources?
Answer: A
Explanation:
The third generation of computing is known for major advances in operating systems, especially the move toward multiprogramming, time-sharing concepts, and improved resource management. During this era, computers became powerful enough to support operating systems that could coordinate multiple programs and users more effectively, enabling shared use of memory, processing time, and peripheral devices. This meant that instead of a computer running only one program at a time with long idle periods, the operating system could schedule tasks, allocate memory, and manage input and output to keep the system busy and efficient. These developments matched the growth of integrated circuits, which improved speed and reliability and made more advanced system software practical. Third-generation systems also emphasized better user interaction through terminals and more standardized system environments. While later generations improved operating systems further, the third generation is widely credited in Information Technology history with establishing the operating system as a central system layer for managing shared resources. Therefore, the correct answer is the third generation.
NEW QUESTION # 27
What is a component of disaster recovery strategies?
Answer: C
Explanation:
Off-site storage is a key component of disaster recovery strategies because it protects critical data from local disasters and facility failures. In Information Technology, disaster recovery focuses on restoring systems, applications, and data after disruptive events such as fires, floods, theft, ransomware, or power failures. If backups are stored only on-site, the same event that damages the primary systems can destroy the backups as well. Off-site storage places backup copies in a physically separate location, reducing the risk of total data loss. It may be implemented through secure tape vaulting, remote backup servers, third-party backup facilities, or cloud-based backup services. Disaster recovery planning typically defines backup schedules, retention periods, recovery procedures, and target recovery goals, such as recovery time objective and recovery point objective. While user authentication supports security and parallel processing relates to performance, they are not core elements that ensure data remains available after a site-level disaster.
Therefore, off-site storage is correctly identified as a component of disaster recovery strategies.
NEW QUESTION # 28
Which component of the data-information-knowledge-wisdom DIKW pyramid includes raw facts?
Answer: D
Explanation:
In the DIKW hierarchy, data represents raw facts and unprocessed observations. Data is typically collected directly from events, measurements, transactions, or sensors and does not carry meaning by itself until it is organized and interpreted. Examples include numbers, symbols, dates, individual readings, or isolated text entries. In Information Technology and Information Systems fundamentals, data is considered the foundation of the DIKW pyramid because all higher levels depend on it. When data is processed, structured, or placed into context, it becomes information. For example, the number 18 alone is simply data, but when connected to a context such as minutes to bake a pizza, it becomes meaningful information. Knowledge goes further by combining information with experience, rules, and understanding to support decisions and actions. Wisdom sits at the top and reflects judgment, ethics, and choosing what should be done in a situation. Therefore, the DIKW component that includes raw facts is data.
NEW QUESTION # 29
What is the primary role of the database administrator?
Answer: A
Explanation:
The core responsibility of a database administrator (DBA) centers around managing and optimizing Database Management Systems (DBMS). This includes:
*Installation and Configuration: Setting up new database instances, applying relevant configurations, and ensuring they align with the organization's needs.
*Maintenance: Performing regular backups, security updates, and patch management to keep the databases secure and healthy.
*Performance Analysis: Monitoring database performance, identifying bottlenecks, and implementing optimizations to ensure efficient data retrieval and operations.
*Troubleshooting: Proactively addressing database errors, resolving operational issues, and ensuring data integrity.
