What do you call the programs that are used to find out possible faults and their causes?

The correct answer is diagnostic software because diagnostic utilities are custom programs written to scan, isolate, and report structural errors across hardware and operating system layers.

• Step 1 (Functional Role): When a system experiences instability, diagnostic software monitors system indicators, tests component integrity (like checking RAM blocks or hard drive sectors), and parses error codes to pinpoint the source of a failure.


• Step 2 (Application): This tool provides IT administrators with the actionable reports needed to replace failing components or apply targeted software patches.


• Incorrect Options:
  
  
  
  • operating system is incorrect because the OS is the master infrastructure program that manages basic hardware resources and runs software, rather than an isolated error-finding utility.
  
  
  • cookies is incorrect because cookies are tiny text data files deposited by web servers onto a browser to track user session states and website preferences.
  
  
  • boot diskettes is incorrect because a boot disk is a physical removable storage medium containing the initialization files required to spin up an operating system, not an analysis application.
