Answer explanation

The first step after pressing the power button is performing the Power-On Self-Test (POST). This diagnostic process checks hardware components to ensure they are functioning properly before loading the operating system.

What is the purpose of the BIOS/UEFI during the boot process?

• To load applications.

• To initialize hardware and load the operating system.

• To manage user accounts.

• To defragment the hard drive.

Answer explanation

The BIOS/UEFI initializes hardware components and performs the Power-On Self-Test (POST) before loading the operating system from the storage device, making it essential for the boot process.

What does POST stand for, and what does it do?

• Power-On System Test; it checks network connectivity.

• Power-On Self-Test; it checks hardware components.

• Program-On Start Test; it loads software applications.

• Protocol-On Security Test; it checks network security.

Answer explanation

POST stands for Power-On Self-Test. It is a diagnostic process that checks the hardware components of a computer during startup to ensure everything is functioning correctly before the operating system loads.

What is the role of the boot loader in the boot process?

• To manage device drivers.

• To load the operating system kernel.

• To manage user accounts.

• To perform system diagnostics.

Answer explanation

The boot loader's primary role is to load the operating system kernel into memory, allowing the system to start up and function. It initializes the system and prepares it for the operating system to take over.

What is the final stage of the boot process before the Windows desktop appears?

• Loading the BIOS.

• Loading the kernel.

• Loading the user interface (GUI).

• Running POST.

Answer explanation

The final stage before the Windows desktop appears is loading the user interface (GUI). This step follows the loading of the kernel and is essential for displaying the graphical environment to the user.
