Operating Systems And Applications_svc

Explanation
The computer's operating system (OS) manages all of the software and hardware on the computer. It controls and coordinates the various components of the computer system, such as the processor, memory, storage devices, input/output devices, and other peripherals. The OS ensures that the hardware resources are allocated and utilized efficiently, and it provides a platform for running software applications. Without the operating system, the hardware components would not be able to function properly and interact with the software.

Explanation
Microsoft created the Windows operating system.

Explanation
Operating systems are typically pre-loaded on computers when they are purchased. This means that when a person buys a new computer, it already has an operating system installed on it. This is done by the computer manufacturer to ensure that the computer is ready to use right out of the box. The operating system is necessary for the computer to function properly and allows the user to interact with the hardware and software on the computer. Therefore, the statement "Operating systems usually come pre-loaded on any computer they buy" is true.

Explanation
Modern operating systems use a graphical user interface, or GUI, which allows users to interact with the computer using visual elements such as windows, icons, and menus. This interface makes it easier for users to navigate and perform tasks on their computers, as they can simply click on icons or select options from menus instead of having to remember and type complex commands. GUIs have become the standard interface for most operating systems today, including Windows, macOS, and Linux.

Explanation
The correct answer is OS X. This is because all of the recent versions of Mac OS have been named with the prefix "OS X," followed by a specific name such as Mavericks or Yosemite. Therefore, OS X is the correct answer as it encompasses all of the recent versions of Mac OS.

Explanation
Linux is a family of open-source operating systems. Unlike Windows and OS X, which are proprietary operating systems, Linux is open-source, meaning that its source code is freely available for anyone to view, modify, and distribute. This allows for a large community of developers to contribute to its development and create different distributions, or versions, of Linux tailored to different needs and preferences. Therefore, Linux is the correct answer as it represents a family of open-source operating systems.

Explanation
A laptop is not considered a mobile device because it is not designed to be easily carried around and used while on the move. Unlike smartphones, MP3 players, and tablets, laptops are typically larger and heavier, with a built-in keyboard and larger screen size. While laptops are portable, they are not as convenient or easily used in mobile situations as the other options listed.

Explanation
The statement that Linux is the most popular operating system in the world is false. While Linux is widely used and highly regarded, it is not the most popular operating system globally. The most popular operating system is Windows, followed by Android for mobile devices. Linux has a significant presence in servers and embedded systems, but it does not have the same level of market share as Windows or Android.

Explanation
Apple iOS is not a desktop application. It is a mobile operating system developed by Apple Inc. for its mobile devices such as iPhones and iPads. Desktop applications, on the other hand, are software programs that are designed to be used on desktop or laptop computers. Word processors, web browsers, and media players are examples of desktop applications as they are typically used on desktop computers.

Explanation
Android OS is an open source operating system primarily used in mobile devices. It is developed by Google and is based on the Linux kernel. Android OS is known for its flexibility and customization options, making it a popular choice for smartphone manufacturers. It offers a wide range of features and supports a large number of applications, making it a versatile operating system for mobile devices.
