    The diff between a web app and a moible app is that the program code for web apps----whereas moible apps are stored on the handheld device so they have to be

    • Arrives only when you use the app, downloaded and installed

    • Is downloaded and installed, retrieved from cloud

    • Is downloaded and installed retrieved only when you use the app

    • None of the above

    Correct Answer
    A. Arrives only when you use the app, downloaded and installed
    Explanation
    The correct answer is "arrives only when you use the app, downloaded and installed". This answer accurately distinguishes between web apps and mobile apps. Web apps are accessed through a web browser and do not require downloading and installation since they are stored on a remote server. On the other hand, mobile apps are specifically designed for handheld devices and need to be downloaded and installed on the device before they can be used. Therefore, the program code for web apps does not need to be downloaded and installed, while mobile apps do.

    Which optical storage technology stores data permanently on a disc, which cannot be subsequently added to or changed

    • Read-only

    • Recordable

    • Rewrtitable

    • None of the above

    Correct Answer
    A. Read-only
    Explanation
    Read-only optical storage technology refers to a type of disc that stores data permanently and cannot be modified or added to after it has been written. This means that the data on the disc is read-only and cannot be altered or deleted. Examples of read-only optical storage technologies include CD-ROMs and DVD-ROMs, which are commonly used for distributing software, movies, and other types of content that do not require modification or editing.

    Chrome os is an example of a ----because it depends substantially on processing and storage provided by cloud-based servers

    • Thin client

    • Forked license

    • ARM

    • Linux

    Correct Answer
    A. Thin client
    Explanation
    Chrome OS is considered an example of a thin client because it relies heavily on processing and storage provided by cloud-based servers. A thin client is a lightweight computer or software that depends on a network connection to access most of its resources and applications from a central server. In the case of Chrome OS, the operating system itself is minimalistic, and most of the computing power and storage are handled by remote servers, making it a prime example of a thin client system.

    A-----is a template that adds the correct formatting as data is entered if someone attempts to enter data in the wrong format the database can be set up to reject that entry or correct it

    • Field format

    • Primary key

    • Database structure

    • Parameter

    Correct Answer
    A. Field format
    Explanation
    A field format is a template that ensures that data entered into a database is in the correct format. This template adds the necessary formatting to the data as it is entered. If someone attempts to enter data in the wrong format, the database can be set up to either reject that entry or automatically correct it to match the specified format. This helps maintain data integrity and consistency within the database.

    Sampling---refers to the number of times per second that a sound is measured during the recording process

    • Rate

    • Compression

    • Depth

    • Sound

    Correct Answer
    A. Rate
    Explanation
    The term "sampling rate" refers to the number of times per second that a sound is measured during the recording process. It determines the level of detail and accuracy in capturing the sound. A higher sampling rate means more samples are taken per second, resulting in a higher quality and more accurate representation of the original sound. Therefore, the correct answer is "rate" because it directly relates to the concept of sampling and its impact on the recording process.

    Two of the most common open source and free software licenses are

    • BSD and GPL

    • EULA and VoIP

    • EULA and GPL

    • None of the above

    Correct Answer
    A. BSD and GPL
    Explanation
    The correct answer is BSD and GPL because these are two of the most widely used open source and free software licenses. BSD (Berkeley Software Distribution) is a permissive license that allows users to modify and distribute the software freely, with minimal restrictions. GPL (General Public License), on the other hand, is a copyleft license that ensures the software remains free and open source by requiring any modifications or derivative works to also be licensed under the GPL. Both licenses have been instrumental in promoting the development and sharing of open source software.

    • Public domain

    • Commercial software

    • Freeware

    Correct Answer
    A. Public domain

    Public domain refers to software that is not protected by copyright and is freely available for anyone to use, modify, and distribute. This means that the software can be copied, distributed, and even resold without any legal restrictions. Unlike proprietary software, which is owned by a specific individual or company and usually requires a license or payment to use, public domain software can be used by anyone for any purpose without any restrictions. Therefore, the given statement "software may be freely copied, distributed and even resold" aligns with the concept of public domain software.
