2. Write short answers to any Eight (8) questions:[8 × 2 = 16]
(i)
What is firmware?
Firmware is permanent software stored on a chip of a hardware device (e.g. BIOS/UEFI on the motherboard) that controls the device’s basic functions.
(ii)
What is the purpose of POST?
POST checks that essential hardware (CPU, RAM, keyboard, drives) works properly before the operating system loads, and reports errors by beeps or messages.
(iii)
What are the built-in tools?
Utilities that come with Windows for maintenance and recovery, such as Task Manager, Disk Cleanup, Event Viewer, Resource Monitor, File History, System Restore and Windows Defender.
(iv)
What is File History? How It is turned on?
File History automatically saves copies of personal files (Documents, Pictures, Desktop etc.) to an external drive. To turn it on: Settings → Update & Security → Backup → Add a drive → switch on “Automatically back up my files”.
(v)
Why is preventive maintenance important?
It prevents failures and data loss, keeps the system fast and secure, and reduces repair cost and downtime.
(vi)
What is Disk Cleanup?
A Windows tool that deletes temporary files, cached data and Recycle Bin items to free disk space.
(vii)
Why is system updating important?
Updates fix bugs, close security holes, update drivers and add new features, keeping the system safe and stable.
(viii)
What is the difference between Quick scan and Full scan.
A Quick scan checks only the common places where malware hides and is fast. A Full scan checks every file and running program on the drive and takes much longer.
(ix)
List the two benefits of running regular disk cleanup.
1) It frees disk space. 2) It improves system speed and performance.
(x)
How can you check updates in Windows?
Start → Settings → Update & Security (Windows Update) → click “Check for updates”.
NOTE:- Give Detailed Answer of given Question.[8×1 = 8]
3.
Explain how deleted files can be recovered using a third-party software.
Third-party recovery software (e.g. Recuva, EaseUS Data Recovery, Disk Drill) can find files that are deleted but not yet overwritten, because deleting only removes the file’s entry while the data stays on disk until new data replaces it. Steps: 1) Stop using the drive to avoid overwriting. 2) Download and install the software on a different drive. 3) Run it and select the drive or folder to scan. 4) Start a Quick or Deep scan. 5) Preview the found files and select those you need. 6) Click Recover and save them to a different drive.
