Explanation (approx. 300 words):
- BlackBerry OS is not commonly used on tablet computers. While iOS, Android, and Windows have been widely deployed on tablets, BlackBerry OS was primarily used on smartphones and failed to gain traction in the tablet market.
- When a computer uses part of the hard drive to supplement RAM (especially when physical RAM is full), it utilizes virtual memory. This allows the system to handle more applications than it could with RAM alone, although it is significantly slower than actual RAM due to the limitations of hard drive speed.
- Linux is an example of an open-source operating system, meaning its source code is freely available to the public for modification and distribution. In contrast, Windows and OS X (now macOS) are proprietary, and DOS, while historically significant, is not actively developed or open-sourced in the modern sense.
- System Restore is not an accessibility utility. Accessibility tools help users with disabilities interact with the system and include features like Narrator (a screen reader), Magnifier (for screen zoom), and Speech Recognition (voice control). System Restore is a system recovery tool, used to revert a computer’s state to a previous point in time.
- Windows 8.1 apps, especially those known as Modern UI or Metro-style apps, are designed to run full screen, emphasizing a touch-friendly interface. This distinguishes them from traditional desktop apps that run in resizable windows.
- File Explorer is the primary file management tool in Windows. It allows users to navigate folders, manage files, and perform operations like copy, move, and delete. Disk Manager manages disk partitions, and Task Manager handles processes and system performance—not file operations.
