Answer: C
NEW QUESTION # 80
What is the goal in improving uptime?
Answer: C
Explanation:
The goal of improving uptime is increasing the portion of time for which systems are operational. In Information Technology operations and service management, uptime measures availability, meaning how consistently an information system is running and accessible when users need it. High uptime is critical for business continuity, customer satisfaction, and meeting service level agreements. Improving uptime involves reducing both planned downtime, such as maintenance windows, and unplanned downtime, such as hardware failures, software crashes, network outages, or cyberattacks. Common strategies include redundancy, failover clustering, monitoring and alerting, preventative maintenance, patch management, and resilient infrastructure design. Increasing time between maintenance events can contribute indirectly, but it is not the definition of uptime improvement. Faster startup processes may reduce downtime duration during restarts, but it is only one factor. Increasing the interval between backups could actually increase risk and does not improve availability. Since uptime is fundamentally the percentage of time systems remain available and functioning, the correct objective is to increase the portion of time the systems are operational. Therefore, the correct answer is option D.
NEW QUESTION # 81
What are two differences between a handheld computer and a desktop?
Choose 2 answers.
Answer: B
Explanation:
1.Smaller Screens:
oVerified Answer: Handheld computers (such as smartphones and tablets) have smaller displays compared to desktop computers.
oExplanation: Handheld screens are typically around 3-5 diagonal inches for phones and up to 9-12 inches for tablets. In contrast, desktop screens range from 20-30 inches diagonally.
oReferences: 1
2.Processing Power and Customizability:
oVerified Answer: Desktop computers usually have more processing power, memory, and storage capacity than handheld devices.
oExplanation: Desktops are ideal for resource-intensive tasks like video editing, gaming, and software development. Handheld devices, while becoming more powerful, are still constrained by size and battery life considerations.
NEW QUESTION # 82
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 # 83
How does application software differ from operating systems?
Choose 2 answers
Answer: A,C
Explanation:
Application software and operating systems serve different purposes within a computer system. The primary distinction lies in their functionality and interaction with the computer's hardware and the user.
*Operating Systems (OS):
oAn OS is system software that acts as an intermediary between the user and the computer hardware.
oIt manages and coordinates the hardware components of a computer system, including the CPU, memory, storage devices, and peripheral devices.
oThe OS provides a platform for application software to run and facilitates user interaction with the system through a user interface.
oExamples include Microsoft Windows, Linux, and macOS.
*Application Software:
oApplication software consists of programs designed to perform specific tasks for the user.
oThese tasks can range from productivity applications like word processors and spreadsheets (Answer A) to communication tools like email clients (Answer B).
oUnlike the OS, application software does not manage hardware resources directly. Instead, it relies on the OS to provide these services.
oExamples include Microsoft Word, Excel, and Mozilla Firefox.
*Key Differences:
oApplication software is run by the end-user to perform specific tasks, while the OS runs in the background, managing the overall operation of the computer system.
oThe OS directly supports and manages the computer hardware system, which is not the case for application software.
References: The information provided here is verified through reliable sources that detail the differences between application software and operating systems12.
