Question 1
ప్రశ్న 1
A desktop computer is switched on. The firmware checks essential hardware such as the processor and memory before attempting to load an operating system. Which startup operation is being performed?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• POST stands for Power-On Self-Test and is performed during the early firmware-controlled startup stage.
• It checks and initializes essential hardware required for the system to continue booting.
• Operating-system recovery and device-driver loading occur later and are not substitutes for POST.

Which sequence most accurately represents the simplified startup process of a normally functioning PC?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• After power is applied, BIOS/UEFI firmware begins execution and performs hardware initialization and POST.
• Firmware then identifies a suitable boot device or boot entry and transfers control to boot code or a boot manager.
• The operating system begins loading only after these earlier startup stages have succeeded.

A newly assembled PC powers on but produces a repeating firmware beep pattern and does not display the operating-system loading screen. What is the most appropriate interpretation?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Firmware beep codes are commonly used to report problems discovered during POST when normal video output may not be available.
• The exact meaning of a beep pattern depends on the motherboard or firmware implementation.
• Because the failure occurs before normal operating-system loading, hardware initialization should be investigated first.

A computer successfully completes POST and BIOS/UEFI detects the internal SSD, but startup stops with a 'No bootable device' message. Which is the most likely class of problem?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Detection of the SSD shows that firmware can communicate with the storage device at the hardware level.
• A 'No bootable device' message indicates that firmware cannot find or use suitable boot information on the selected device.
• This may result from boot-order, boot-entry, boot-loader or operating-system installation problems.
