Failing I/O controllers, on either the motherboard or separate cards. Failing I/O devices. Inadequate or failing power supply. Cooling problems are usually obvious upon inspection. A failing motherboard or processor can be identified by swapping them with functioning parts. Memory can be checked by booting to a diagnostic tool, like memtest86 ...
It can simulate certain conditions such as low memory, I/O verification, pool tracking, IRQL checking, deadlock detection, DMA checks, IRP logging, etc. [1] The verifier works by forcing drivers to work with minimal resources, making potential errors that might happen only rarely in a working system manifest immediately.
ILOVEYOU, sometimes referred to as the Love Bug or Loveletter, was a computer worm that infected over ten million Windows personal computers on and after 5 May 2000. It started spreading as an email message with the subject line "ILOVEYOU" and the attachment "LOVE-LETTER-FOR-YOU.TXT.vbs". [1]
To combat computer viruses and other malicious software, many security advisory organizations and anti-virus software developers compile and publish virus lists. When a new virus appears, the rush begins to identify and understand it as well as develop appropriate counter-measures to stop its propagation.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
The I/O request packet mechanism is also used by Digital Equipment Corporation's VMS operating system, and was used by Digital's RSX-11 family of operating systems before that. An I/O request packet in RSX-11 is called a directive parameter block, [ 1 ] as it is also used for system calls other than I/O calls.
A hard disk drive failure occurs when a hard disk drive malfunctions and the stored information cannot be accessed with a properly configured computer. A hard disk failure may occur in the course of normal operation, or due to an external factor such as exposure to fire or water or high magnetic fields , or suffering a sharp impact or ...
A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [ 1 ] [ 2 ] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
