  2. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    Machine code is by definition the lowest level of programming detail visible to the programmer, but internally many processors use microcode or optimize and transform machine code instructions into sequences of micro-ops. Microcode and micro-ops are not generally considered to be machine code; except on some machines, the user cannot write ...

  3. Source code - Wikipedia

    en.wikipedia.org/wiki/Source_code

    In computing, source code, or simply code or source, is text (usually plain text) that conforms to a human-readable programming language and specifies the behavior of a computer. A programmer writes code to produce a program that runs on a computer. Since a computer, at base, only understands machine code, source must be translated in order to ...

  4. Compiler - Wikipedia

    en.wikipedia.org/wiki/Compiler

    The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program.: p1 There are many different types of compilers which produce output in different useful forms.

  5. History of free and open-source software - Wikipedia

    en.wikipedia.org/wiki/History_of_free_and_open...

    In the 1950s and 1960s, computer operating software and compilers were delivered as a part of hardware purchases without separate fees. At the time, source code, the human-readable form of software, was generally distributed with the software providing the ability to fix bugs or add new functions. [1] Universities were early adopters of ...

    Blender – Computer graphics software featuring modeling, sculpting, texturing, rigging, simulation, rendering, camera tracking, video editing, and compositing. MakeHuman. OpenFX – Modeling and animation software with a variety of built-in post processing effects. Seamless3d – Node-driven 3D modeling software.

  7. Native (computing) - Wikipedia

    en.wikipedia.org/wiki/Native_(computing)

    Native (computing) In computing, native software or data-formats are those that were designed to run on a particular operating system. In a more technical sense, native code is code written specifically for a certain processor. [1] In contrast, cross-platform software can be run on multiple operating systems and/or computer architectures .

  8. Low-level programming language - Wikipedia

    en.wikipedia.org/wiki/Low-level_programming_language

    Low-level programming language. A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture —commands or functions in the language map that are structurally similar to processor's instructions. Generally, this refers to either machine code or assembly language.

  9. Assembly language - Wikipedia

    en.wikipedia.org/wiki/Assembly_language

    Assembly language (or Assembler) is a compiled, low-level computer language. It is processor-dependent since it basically translates the Assembler's mnemonics directly into the commands a particular CPU understands, on a one-to-one basis. These Assembler mnemonics are the instruction set for that processor.
