Core Dump - Background

Background

Before the advent of disk operating systems and the ability to record large data files, core dumps were paper printouts of the contents of memory, typically arranged in columns of octal or hexadecimal numbers (a "hex dump"), sometimes accompanied by their interpretations as machine language instructions, text strings, or decimal or floating-point numbers (cf. disassembler). In more recent operating systems, a "core dump" is a file containing the memory image of a particular process, or the memory images of parts of the address space of that process, along with other information such as the values of processor registers. These files can be printed or viewed as text, or analysed with specialised tools such as objdump.

Famous quotes containing the word background:

    ... every experience in life enriches one’s background and should teach valuable lessons.
    Mary Barnett Gilson (1877–?)

    They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.
    Jimmy Carter (James Earl Carter, Jr.)

    Pilate with his question “What is truth?” is gladly trotted out these days as an advocate of Christ, so as to arouse the suspicion that everything known and knowable is an illusion and to erect the cross upon that gruesome background of the impossibility of knowledge.
    Friedrich Nietzsche (1844–1900)
