When performing computer recovery operations after a system crash, the startup disk is used to

A.

Restore the system to an earlier time

B.

Update the application packages

C.

Backup deleted users file

D.

Recover the system disk from an image file

Correct answer is D

When performing computer recovery operations after a system crash, the startup disk is used to recover the system disk from an image file.

A startup disk typically contains essential system files and tools that are required to boot the computer and initiate recovery procedures. One common approach to recovery after a system crash is to use an image of the system disk taken at a stable and functional state. This image is often referred to as a "system image" or "backup image." By using the startup disk and this image, you can restore the entire system to a previous state, which can include the operating system, applications, and data. This process helps in recovering from crashes and issues that render the system inoperable.

Computer malware is detected by

A.

Adware

B.

Logic bomb

C.

Antivirus

D.

Antiglare

Correct answer is C

Computer malware is detected by antivirus software. Antivirus software is designed to identify, prevent, and remove various types of malicious software, commonly referred to as malware. This includes viruses, worms, trojans, spyware, adware, and other malicious programs that can harm or compromise a computer system. Antivirus software scans files, programs, and incoming data for patterns and behaviors associated with known malware, and it takes actions to quarantine or remove the detected threats. The other options mentioned—adware, antiglare, and logic bomb—are not directly related to detecting malware. Adware is a type of potentially unwanted software, antiglare refers to a screen feature, and a logic bomb is a type of malicious code that triggers when specific conditions are met.

B.

Computerized axial tomography

C.

Optical character recognition

D.

Global positioning system

Correct answer is B

One application of ICT (Information and Communication Technology) in medicine is computerized axial tomography (CAT or CT scan).
