  2. Binary code - Wikipedia

    en.wikipedia.org/wiki/Binary_code

    Binary code. The word 'Wikipedia' represented in ASCII binary code, made up of 9 bytes (72 bits). A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also ...

  3. Application binary interface - Wikipedia

    en.wikipedia.org/wiki/Application_binary_interface

    In computer software, an application binary interface (ABI) is an interface between two binary program modules. Often, one of these modules is a library or operating system facility, and the other is a program that is being run by a user. An ABI defines how data structures or computational routines are accessed in machine code, which is a low ...

  4. Binary file - Wikipedia

    en.wikipedia.org/wiki/Binary_file

    A binary file is a computer file that is not a text file. [1] The term "binary file" is often used as a term meaning "non-text file". [2] Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text, such as older Microsoft Word document files, contain the text of ...

  5. Executable and Linkable Format - Wikipedia

    en.wikipedia.org/wiki/Executable_and_Linkable_Format

    An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections. In computing, the Executable and Linkable Format[ 2 ] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.

  6. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers machine code is "the binary representation of a computer program which is actually read and interpreted by the computer. A program in machine ...

  7. Executable - Wikipedia

    en.wikipedia.org/wiki/Executable

    In computer science, executable code, an executable file, or an executable program, sometimes simply referred to as an executable or binary, causes a computer "to perform indicated tasks according to encoded instructions ", [2] as opposed to a data file that must be interpreted (parsed) by an interpreter to be functional. [3]

  8. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.

  9. Computer program - Wikipedia

    en.wikipedia.org/wiki/Computer_program

    t. e. A computer program is a sequence or set [a] of instructions in a programming language for a computer to execute. It is one component of software, which also includes documentation and other intangible components. [1] A computer program in its human-readable form is called source code.
