  2. Segmentation fault - Wikipedia

    en.wikipedia.org/wiki/Segmentation_fault

    Segmentation faults can also occur independently of page faults: illegal access to a valid page is a segmentation fault, but not an invalid page fault, and segmentation faults can occur in the middle of a page (hence no page fault), for example in a buffer overflow that stays within a page but illegally overwrites memory.

  3. Medical error - Wikipedia

    en.wikipedia.org/wiki/Medical_error

    Variations in healthcare provider training & experience [45] [52] and failure to acknowledge the prevalence and seriousness of medical errors also increase the risk. [53] [54] The so-called July effect occurs when new residents arrive at teaching hospitals, causing an increase in medication errors according to a study of data from 1979 to 2006 ...

  4. Bus error - Wikipedia

    en.wikipedia.org/wiki/Bus_error

    On x86 there exists an older memory management mechanism known as segmentation. If the application loads a segment register with the selector of a non-present segment (which under POSIX-compliant OSes can only be done with assembly language), the exception is generated. Some OSes used that for swapping, but under Linux this generates SIGBUS.

  5. Memory protection - Wikipedia

    en.wikipedia.org/wiki/Memory_protection

    Protection may encompass all accesses to a specified area of memory, write accesses, or attempts to execute the contents of the area. An attempt to access unauthorized [a] memory results in a hardware fault, e.g., a segmentation fault, storage violation exception, generally causing abnormal termination of the offending process.

  6. Planning fallacy - Wikipedia

    en.wikipedia.org/wiki/Planning_fallacy

    The segmentation effect is defined as the time allocated for a task being significantly smaller than the sum of the time allocated to individual smaller sub-tasks of that task. In a study performed by Forsyth in 2008, this effect was tested to determine if it could be used to reduce the planning fallacy.

  7. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    A 68451 MMU, which could be used with the Motorola 68010. A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.

  8. Congenital vertebral anomaly - Wikipedia

    en.wikipedia.org/wiki/Congenital_vertebral_anomaly

    Block vertebrae occur when there is improper segmentation of the vertebrae, leading to parts of or the entire vertebrae being fused. The adjacent vertebrae fuse through their intervertebral discs and also through other intervertebral joints so that it can lead to blocking or stretching of the exiting nerve roots from that segment.

  9. Segmentation in the human nervous system - Wikipedia

    en.wikipedia.org/wiki/Segmentation_in_the_human...

    The nervous system segmentation confers several developmental advantages to the vertebrate body as humans possess a body plan that is bilaterally segmented at the nervous system level. The segmentation is involved at all levels of the human nervous system with increasing level of complexity in the innervation from the brain to limbs. [1]
