NEW QUESTION # 77
Which type of network is used to connect wireless headphones to a smartphone?

Answer: C

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 # 78

Answer: D


NEW QUESTION # 79
Which method is frequently used to protect software?

Answer: B

Explanation:
Software protection involves safeguarding software applications from unauthorized use, distribution, or reproduction. Various methods are employed to protect software, but one of the most frequently used approaches is through copyrights. Here's why:
1.Copyrights:
oDefinition: Copyright protection grants exclusive rights to the creator or owner of the software. It prevents others from copying, distributing, or using the software without permission.
oHow It Works:
When a software developer creates an original program, they automatically hold the copyright to it.
The copyright holder can specify licensing terms and conditions, allowing or restricting certain uses.
Users must comply with these terms to legally use the software.
oBenefits:
Legal Protection: Copyright laws provide legal recourse against infringement.
Revenue Control: Developers can license their software and generate revenue.
Innovation Encouragement: Copyright protection encourages innovation by rewarding creators.
oReferences: 12
2.Other Methods:
oGNU General Public License (GPL): GPL is an open-source license that allows users to freely use, modify, and distribute software. However, it requires derivative works to be open-source as well.
oFair Use: Fair use is a legal doctrine that permits limited use of copyrighted material without permission for purposes such as criticism, commentary, or education.
oTrademarks: Trademarks protect brand names, logos, and symbols associated with software. While not directly related to software protection, trademarks play a role in branding and identity.
In summary, while other methods exist, copyrights remain a fundamental and frequently used approach to protect software from unauthorized use and ensure developers' rights are respected.

NEW QUESTION # 80
Which component of an operating system allows the operating system to run applications?

Answer: B

Explanation:
The kernel is the core component of an operating system that enables applications to run by managing system resources and providing essential services. In Information Technology, applications do not directly control the CPU, memory, or hardware devices. Instead, they request services from the operating system through system calls, which are handled by the kernel. The kernel manages process creation and execution, memory allocation, multitasking, and communication between software and hardware. It also enforces protection and security boundaries so one program cannot easily interfere with another or with the operating system itself.
The user interface affects how users interact with the system, but it is not the component that actually runs programs. The file manager handles organization and access to files, and drivers allow the operating system to communicate with specific hardware devices, such as printers and network cards. Because the kernel controls process execution and resource management, it is the operating system component that allows applications to run.


NEW QUESTION # 81

2.Stores IP addresses and aliases in a table on the server: DNS servers maintain records that map domain names to corresponding IP addresses. These records are stored in distributed databases across various DNS servers, ensuring efficient and reliable resolution of domain names1.
