Which of the following depicts a significant difference between proprietary software and open-source software? Compatability Issues , single-Platform vs Cross-Platform , Licensing and sources code accessibility , advanced Installation options

Back

Licensing and sources code accessibility

Answer explanation

Explanation

Proprietary software's source code is kept confidential and users need to purchase a license to use it, while open-source software's source code is freely accessible and can be modified and redistributed under its licensing terms. Both types of software can be either single-platform or cross-platform. Advanced installation options are steps involved in software installation, and do not specifically differentiate proprietary from open-source software. While compatibility can depend on the specifics of the software, it is not a specific differentiator between proprietary and open-source software.

Alice is experiencing slow browsing speed and frequent browser crashes. What could potentially fix this situation? Options: Removing Browser extensions, Clearing the cache, Switching the private browsing, Deactivating client-side Scripting

Back

Clearing the cache

Answer explanation

Clearing browser cache can improve browsing speed and stability, as it frees up memory space and discards old, irrelevant data. Overloaded caches can cause browser crashes. Private browsing mode does not inherently improve speed or reduce browser crashes. It's primarily used for privacy, not performance enhancement. While deactivating client-side scripting can increase security, it's primarily relevant for browsing speed if the scripts are large, intensive, or poorly written. However, it doesn’t address browser crashes due to memory overload. While removing unused extensions can also free up memory, it won't directly improve browser crashes or speed unless a specific extension is causing these issues.

What type of software is Microsoft Excel, used by Jennifer, a financial analyst at Dion Training, to analyze complex financial data? Options: Database Software, Spreadsheet Software, Word processing Software, Visual Diagramming Software

Back

Spreadsheet Software

Answer explanation

Explanation

Microsoft Excel is the most popular spreadsheet software in the world. It is a powerful tool that can be used for a variety of tasks, including data analysis, financial modeling, and creating charts and graphs. Although database software can store large amounts of data, it doesn't readily provide the functions to analyze it. While it can help in visual representation, visual diagramming software wouldn't be apt for performing calculations or analyzing data. Word processing software is for document creation and editing, not suitable for performing data analysis.

Lara, a small business owner, wants to acquire new software for her employees. Her staff varies in size from season to season, so she needs a license that can cater for that. Which form of licensing should she consider?

Back

Concurrent License

Answer explanation

A concurrent license allows a specified number of users to access the software at any given time. This is optimal for Lara's fluctuating team size, as it provides flexibility. Although group use/site license permit multiple users, it sets a fixed user number. This could present issues for Lara's variable staff size. Despite offering multiple user access, an open-source license might not offer Lara the business-specific features or professional customer support a commercial product with a concurrent license would. Single-use licenses only permit one user to install and use the software. It wouldn't suit Lara's needs as she has multiple employees who need to use the software.

Patrick, a systems analyst at Dion Training, wants to install a small, lightweight software tool on his laptop, without the necessity of network access. Which application delivery method is most suitable for his needs?

Back

Locally installed

Answer explanation

Locally installed delivery is the most suitable choice as a locally installed application resides on the device and does not require network connectivity to function. Cloud hosted delivery requires an active internet connection, and hence it would not cater to the need for an application that runs without network access. While a local-network-hosted application does not need internet access, it still requires a network for data sharing and operation, which makes this method an unsuitable choice here. While SaaS is a delivery model, it relies on an active internet connection to provide software services. Therefore, this model is not suitable for the requirements.

Which term refers to instances of running applications actively executing tasks in the operating system?

Back

Processes

Answer explanation

Processes refer to the active execution instances of applications or tasks running in an operating system. Drivers are software pieces that enable communication with hardware. They are not instances of running applications. Services are background tasks that run without user participation on the operating system, but they do not necessarily refer to active application instances. Task scheduling is an operating system utility feature that sets up tasks to run automatically at certain times. It is not a term for actively executing applications.

What distinguishes an open-source license from a proprietary license?

Back

Proprietary licenses prevent modifications of the source code, whereas open-source licenses allow it.

Answer explanation

Proprietary licenses restrict the use, modification, and sharing of the code, while open-source licenses promote openness by permitting individuals to inspect, modify, and distribute the software source code. Open-source software is usually available at no cost and permits public access to the source code for review and modification. Proprietary software, on the other hand, often requires a license fee and restricts access to the source code. Proprietary licenses usually discourage community contribution because they limit access to and modification of the source code. Conversely, open-source licenses encourage community development and contribution because they allow for access to and modification of the source code. Open-source licenses permit anyone to review, modify, and distribute the software's source code, while proprietary licenses prevent unauthorized modification or sharing of the source code.

What’s the difference between a concurrent license and a group/site license?

Back

Concurrent license restricts simultaneous usage, while a group license restricts by the number of devices.

Answer explanation

In a concurrent license approach, the number of simultaneous users accessing the software at any given time is limited. This is regardless of where these users are located. On the other hand, a group or site license allows an organization to install and use the software across numerous devices within a specified organizational unit or location. The concept of geographical location is more important in this type of licensing. The payment model is not an inherent difference between concurrent and group/site licenses. Access to or control of the source code is not a difference between concurrent and group/site licenses. The number of installationsis not necessarily a demarcation between concurrent and group/site licenses.

Steve, a network administrator at Dion Training, wants to stop an unresponsive application on a Windows PC. Which feature of the operating system will facilitate this?

Back

process management /scheduling

Answer explanation

Process management/scheduling controls how programs run on the operating system. In this context, it allows the user to terminate the unresponsive application. Though part of disk management, disk defragmentation is not associated with stopping unresponsive applications. While memory management relates to how the OS allocates memory, it doesn't help in ending an unresponsive application. Device compatibility has more to do with ensuring hardware devices work properly with the operating system, not with managing applications.

What should Jane do to speed up her browser experiencing slow performance due to a specific extension? Options: Clear her browser's cache, remove or disable the troublesome extension, Add new extensions, Enable Private browsing

Back

remove or disable the troublesome extension

Answer explanation

Disabling or removing the extension that's causing slow performance would increase browser speed. Private browsing mainly ensures that your surfing data isn't stored, it doesn't inherently speed up the browser. Adding new extensions could further slow down the browser, as they can consume resources. Clearing the cache will remove stored data, potentially increasing loading speed for websites but the problem with the extension remains.
