What describes the boot process?

The boot process refers to the sequence of events that occur when a computer is powered on or restarted. This sequence begins with the computer's hardware initializing and conducting a self-test, known as the POST (Power-On Self-Test), which checks for essential components like the CPU, RAM, and storage devices. Once the POST is successful, the system firmware (often the BIOS or UEFI) takes over, locating and loading the operating system from a storage device, typically the hard drive or SSD, into the computer's memory. After the operating system loads, it initializes system settings and starts up background services, allowing the user to interact with the system.

Understanding this process is crucial for troubleshooting various technical issues; for instance, if a computer fails to boot, it may be due to hardware malfunctions or system corruption. This knowledge also lays the foundation for deeper exploration into operating system functionality and hardware integration. The other choices do not correctly represent the boot process, as they focus on software installation, cybersecurity and internet connectivity, which are distinct functions unrelated to the core booting sequence.
