Question 1

What are mobile systems?

Accepted Answer

Mobile systems are information systems that support users in motion. Mobile systems users access the system from any place-at home, at work, while traveling-using any smart device, such as smartphone, tablet, or PC. Mobile systems users move not only geographically, they also move from device to device. The major elements in a mobile system are users in motion, mobile devices, wireless connectivity, and cloud-based resources.

Question 2

In a ________ application, the browser provides a relatively consistent platform for the application.

Accepted Answer

A Web application runs on a browser, which provides a platform that is relatively consistent across different devices and operating systems. This is in contrast to native applications, which are built for specific operating systems, and thick-client applications, which require software to be installed on each client device. Virtual applications are typically run in a virtual machine environment.

Question 3

A browser provides a more-or-less consistent environment for a Web application when it is developed to be run outside the browser.

Accepted Answer

A browser provides a highly variable environment for a Web application, depending on factors such as browser type, version, and user settings. When a Web application is developed to be run outside the browser, it is usually designed to function consistently across different systems and configurations.

Question 4

Which of the following is TRUE about the impact of mobile systems on data usage in information systems?

Accepted Answer

Mobile systems have smaller screen sizes, which means there is less device real estate available to display information. This can impact how data is presented and consumed in information systems.

Question 5

Logan, a professional programmer and developer, develops a Web mobile application. The application allows users to book cabs for rides within the city. Which of the following languages is Logan most likely to have used to develop this app?

Accepted Answer

Logan is most likely to have used HTML5 to develop the mobile web application, as it is the standard markup language used for structuring and presenting content on the web. The application is accessed through a mobile device's web browser, so developing it using a language like VB.Net or C++ would not be ideal. Objective-C is used for developing native iOS applications, which are downloaded and run directly on a user's iPhone, and it would not be the best choice for a web application.

Question 6

Which of the following is a major element of mobile systems?

Accepted Answer

Cloud-based resources are a major element of mobile systems as they allow for on-demand access to data and applications from anywhere with an internet connection.

Question 7

Which of the following statements about native applications is TRUE?

Accepted Answer

Native applications are developed specifically for a particular operating system (such as iOS or Android) and can only run on that system. They are not dependent on browsers or web technologies. Option (A) is false because native apps are usually developed by professional developers. Option (B) is false because it describes web applications, not native apps. Option (D) is also false because native apps are not dependent on browser platforms.

Question 8

In the context of industry changes, which of the following statements is TRUE of mobile systems?

Accepted Answer

Mobile systems allow organizations to be more flexible in their staffing, including the effective use of part-time employees and independent contractors, by enabling remote access to organizational resources and communication tools.

Question 9

Which of the following statements is TRUE of Web applications developed for mobile systems?

Accepted Answer

Web applications developed for mobile systems can be developed by professional programmers and technically oriented Web developers or business professionals. It is not necessary to have specialized knowledge for mobile platforms like in the case of native applications. Additionally, web applications can run on multiple platforms, making them more cost-effective compared to developing separate native applications for each platform. Thin-client applications refer to web applications, and it is not necessarily easier to earn money from them as opposed to native applications. Web applications also do not require multiple versions as they run on different devices using standard web browsers.

Question 10

Continually evolving software leads to a decline in entrepreneurial opportunities.

Accepted Answer

Continually evolving software creates new and different entrepreneurial opportunities as the technology and market needs change. While it may make some existing business models obsolete, it also opens up new avenues for innovative entrepreneurs.

Question 11

Briefly describe the mobile system effect for each of the five components of an information system.

Accepted Answer

The answer of Briefly describe the mobile system effect for...

Question 12

________ languages can be used to create difficult, complex applications, and, if used properly, will result in high-performance code that is easy to alter when requirements change.

Accepted Answer

Object-oriented languages, such as Java and C++, allow for complex programs to be built with reusable code in the form of objects. They also offer features like inheritance and encapsulation, which makes it easier to modify code as requirements change. Additionally, modern object-oriented languages include memory management, making programming in these languages more straightforward and less error-prone compared to low-level programming languages like Assembly or Hardware Description languages.

Question 13

Web applications can be developed by less-skilled, lesser-paid employees; they are considerably cheaper to develop than ________ applications.

Accepted Answer

Native applications are usually developed by highly-skilled employees and require a lot of time and resources to develop, making them much more expensive compared to web applications which can be developed by less-skilled employees and are considerably cheaper to develop.

Question 14

Web mobile applications ________.

Accepted Answer

Web mobile applications are developed using web technologies like HTML, CSS, JavaScript, and are accessed through a mobile browser. Therefore, they are limited by the capabilities of the browser used on the device, rather than specific to a particular operating system or programming language. They can be developed by both professional programmers and amateurs with coding experience.

Question 15

Which of the following is a characteristic of a mobile device?

Accepted Answer

Mobile devices are known for their portability and convenience. They are designed to be small and lightweight, enabling users to carry them easily in their pocket or bag. This makes them perfect for on-the-go computing and communication. Option A is incorrect because mobile devices may have touchscreen keyboards or voice recognition software. Option B is also incorrect because many mobile devices are designed to be energy-efficient to preserve battery life. Option C is incorrect because wireless connectivity is one of the defining characteristics of mobile devices, enabling users to connect to the internet, transfer data, and communicate wirelessly with other devices.

Question 16

Mobile systems users only move geographically, not from device to device.

Accepted Answer

Mobile systems users can move from one device to another, such as switching from a smartphone to a tablet or laptop. This is often facilitated through cloud-based services that allow for synchronization of data and access to applications across multiple devices.

Question 17

________ systems are information systems that support users in motion.

Accepted Answer

Mobile systems are specifically designed to support users who are in motion, such as those who are traveling or working remotely. They are accessed through smartphones, tablets, and other mobile devices, which enable users to receive real-time updates and access relevant information whenever and wherever they need it. Data systems and web-based systems may also be accessed through mobile devices, but they are not specifically designed for mobile use. Remote systems refer to any system that can be accessed remotely, regardless of whether the user is in motion or not.

Question 18

A mobile device is a small, lightweight, power-conserving computing device that is capable of wireless connectivity.

Accepted Answer

A mobile device is typically small and lightweight, designed for easy portability. It also usually has wireless connectivity options, such as Wi-Fi, Bluetooth, or cellular data. Examples of mobile devices include smartphones, tablets, e-readers, and smartwatches.

Question 19

Mobile systems are information systems that support users in motion.

Accepted Answer

Mobile systems are designed to support users who are not stationary, typically using portable devices such as smartphones or tablets. These systems often rely on wireless networks to connect users to information and services that they need while on the go.

Question 20

A ________ application is a thick-client application that is designed to work with a particular operating system, and sometimes only with a particular mobile device that runs that operating system.

Accepted Answer

A native application is designed specifically for a certain operating system or device, providing better performance and functionality compared to other types of applications. It is installed on the device, making it independent of the internet connection and allowing access to device-specific functions. Virtual applications are hosted on a server and accessed remotely, while remote applications are designed to run on a different computer than the one the user is working on. Browser-based applications run within a web browser, and they require an internet connection, making them less responsive and less robust than native applications.
