Which is not a function of operating system? (a) Memory management (b) Virus protection (c) Disk management (d) File management

Virus protection is not a function of the operating system. A database of known malware types is compared to the files and programs on your computer by antivirus software to begin its operation. It will also scan systems for any possible threats from new or unidentified malware kinds because hackers constantly create and spread new infections.

Functions of the Operating System

  1. Memory management
  2. Disk management
  3. File management

Antivirus:

Software designed primarily to assist in the detection, prevention, and removal of malware (malicious software). In addition to assisting in protecting your files and hardware from viruses like Trojan horses, worms, and spyware, comprehensive virus protection solutions can offer extra security features like customized firewalls and URL blocking.

How does it work?

  • When a virus-containing file is found, it is frequently quarantined by the application and/or marked for deletion, making it inaccessible and lowering the risk to your device.
  • The majority of programs typically use three different detection techniques: specific detection, which locates known malware by identifying known suspicious file structures, generic detection, which looks for known malware types, parts, or patterns that share a common codebase, and heuristic detection, which searches for unknown viruses by identifying known suspicious file structures.

Therefore, OS does not have the ability to protect against viruses. It is an Antivirus and Firewall feature.

Summary:

Which is not a function of the operating system? (a) Memory management (b) Virus protection (c) Disk management (d) File management

The operating system does not have any control over virus defense. Software is mostly intended to help with malware detection, prevention, and removal (malicious software).
