MCQ Detailed View

A computer cannot boot without an operating system because the OS is the fundamental software that manages hardware and enables the system to function properly after startup. Booting is the process of starting a computer and loading the operating system into main memory (RAM).

When a computer is powered on, it first runs a small program called BIOS or UEFI from the motherboard, which performs basic hardware checks. This program then looks for a bootable device (like a hard drive or SSD) that contains the operating system. If an operating system is not found, the computer cannot proceed with the boot process and will usually display an error like “No operating system found.”
