  2. Zero-byte file - Wikipedia

    en.wikipedia.org/wiki/Zero-byte_file

    Zero-byte files may arise in cases where a program creates a file but aborts or is interrupted prematurely while writing to it. Because writes are cached in memory and only flushed to disk at a later time , a program that does not flush its writes to disk or terminate normally may result in a zero-byte file. When the zero-byte file is made ...

  3. 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.

  4. No-disc crack - Wikipedia

    en.wikipedia.org/wiki/No-disc_crack

    A No-disc crack, No-CD crack or No-DVD crack is an executable file or a special "byte patcher" program which allows a user to circumvent certain Compact Disc and DVD copy protection schemes. They allow the user to run computer software without having to insert their required CD-ROM or DVD-ROM. This act is a form of software cracking.

  8. Soft error - Wikipedia

    en.wikipedia.org/wiki/Soft_error

    It is extremely hard to maintain the material purity needed. Controlling alpha particle emission rates for critical packaging materials to less than a level of 0.001 counts per hour per cm 2 (cph/cm 2) is required for reliable performance of most circuits. For comparison, the count rate of a typical shoe's sole is between 0.1 and 10 cph/cm 2.

  9. File system - Wikipedia

    en.wikipedia.org/wiki/File_system

    Many file systems access data as a stream of bytes. Typically, to read file data, a program provides a memory buffer and the file system retrieves data from the medium and then writes the data to the buffer. A write involves the program providing a buffer of bytes that the file system reads and then stores to the medium.
