In the Windows operating system, files and folders that are deleted are moved to the Recycle Bin, where they can be restored or permanently removed.

Airplane mode disables wireless communications (Wi-Fi, cellular, Bluetooth), which reduces the power consumption and processing load on the device, helping to prevent overheating.

Computers have thermal protection mechanisms; if the internal temperature exceeds safe limits due to poor ventilation or fan failure, the system will shut down to prevent hardware damage.

Task Manager is primarily used to monitor running applications and system performance. It allows users to view active processes and end those that are unresponsive.

Mark Zuckerberg is the primary co-founder of Facebook. The other individuals listed are not associated with the creation of the platform.

Google Chrome is currently the most widely used web browser globally. While other options are browsers, they do not hold the same market share.

In Windows Explorer, users can sort files by various attributes, including 'Date modified'. This allows files to be organized chronologically by their last change.

In many systems, the # wildcard represents numeric characters (0-9). The @ symbol typically represents text/letters, and % has various uses depending on context. Note that options B and C are identical (@), indicating a question error.

Binary code is a base-2 number system that uses only two digits: 0 and 1. These represent the off and on states of electronic switches.

The word 'binary' is pronounced 'BY-nuh-ree'. Option D is the closest phonetic approximation among the choices provided.

Google Chrome is a widely used web browser. The other options contain misspellings or refer to file management tools (Windows Explorer).

Ctrl+C is the standard keyboard shortcut used to copy a selected file or text to the clipboard.

File properties provide detailed information about a file, such as its type, size, location, and creation date. This is often referred to as metadata.

A library in Windows is a virtual folder that aggregates content from various locations on the computer to present a collection of similar files (like documents or pictures) in one place.
