  2. Data recovery - Wikipedia

    en.wikipedia.org/wiki/Data_recovery

    Data damage can be caused when, for example, a file is written to a sector on the drive that has been damaged. This is the most common cause in a failing drive, meaning that data needs to be reconstructed to become readable. Corrupted documents can be recovered by several software methods or by manually reconstructing the document using a hex ...

    The adjacent image is a corrupted image file in which most of the information has been lost. Some types of malware may intentionally corrupt files as part of their payloads , usually by overwriting them with inoperative or garbage code, while a non-malicious virus may also unintentionally corrupt files when it accesses them.

  4. Data degradation - Wikipedia

    en.wikipedia.org/wiki/Data_degradation

    Data degradation is the gradual corruption of computer data due to an accumulation of non-critical failures in a data storage device. It is also referred to as data decay, data rot or bit rot. [1] This results in a decline in data quality over time, even when the data is not being utilized.

    The program includes text styles, text cleaning, and can read and save ASCII, Unicode, RTF, older formats such as AppleWorks and older versions of Microsoft Word. It can read text out loud, play audio files, and run QuickTime movies. Tex-Edit Plus supports PowerPC and Intel Macs. It requires Mac OS 10.4 through 10.12.

    Prior to the advent of macOS, the classic Mac OS system regarded the content of a file (the data fork) to be a text file when its resource fork indicated that the type of the file was "TEXT". [7] Lines of classic Mac OS text files are terminated with CR characters. [8] Being a Unix-like system, macOS uses Unix format for text files. [8]

  7. File verification - Wikipedia

    en.wikipedia.org/wiki/File_verification

    File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.

  8. Error detection and correction - Wikipedia

    en.wikipedia.org/wiki/Error_detection_and_correction

    A parity bit is a bit that is added to a group of source bits to ensure that the number of set bits (i.e., bits with value 1) in the outcome is even or odd. It is a very simple scheme that can be used to detect single or any other odd number (i.e., three, five, etc.) of errors in the output.

  9. Memory corruption - Wikipedia

    en.wikipedia.org/wiki/Memory_corruption

    When the corrupted memory contents are used later in that program, it leads either to program crash or to strange and bizarre program behavior. Nearly 10% of application crashes on Windows systems are due to heap corruption. [1] Modern programming languages like C and C++ have powerful features of explicit memory management and pointer ...
