  2. Caesar cipher - Wikipedia

    en.wikipedia.org/wiki/Caesar_cipher

    In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.

  3. History of compiler construction - Wikipedia

    en.wikipedia.org/wiki/History_of_compiler...

    The parser detects and identifies the reserved words and symbols of the specific language from a stream of text and returns these as tokens to the code which implements the syntactic validation and translation into object code. This second part of the compiler can also be created by a compiler-compiler using a formal rules-of-precedence syntax ...

  4. Tombstone diagram - Wikipedia

    en.wikipedia.org/wiki/Tombstone_diagram

    Tombstone diagram representing an Ada compiler written in C that produces machine code. Representation of the process of bootstrapping a C compiler written in C, by compiling it using another compiler written in machine code. To explain, the lefthand T is a C compiler written in C that produces machine code.

  5. Translator (computing) - Wikipedia

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

    t. e. A translator or programming language processor is a computer program that converts the programming instructions written in human convenient form into machine language codes that the computers understand and process. It is a generic term that can refer to a compiler, assembler, or interpreter —anything that converts code from one ...

  6. Just-in-time compilation - Wikipedia

    en.wikipedia.org/wiki/Just-in-time_compilation

    MSVC. v. t. e. In computing, just-in-time ( JIT) compilation (also dynamic translation or run-time compilations) [1] is compilation (of computer code) during execution of a program (at run time) rather than before execution. [2] This may consist of source code translation but is more commonly bytecode translation to machine code, which is then ...

  7. Source-to-source compiler - Wikipedia

    en.wikipedia.org/wiki/Source-to-source_compiler

    t. e. A source-to-source translator, source-to-source compiler ( S2S compiler ), transcompiler, or transpiler [1] [2] [3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.

  8. Source code - Wikipedia

    en.wikipedia.org/wiki/Source_code

    Source code is the form of code that is modified directly by humans, typically in a high-level programming language. Object code can be directly executed by the machine and is generated automatically from the source code, often via an intermediate step, assembly language. While object code will only work on a specific platform, source code can ...

  9. Cut, copy, and paste - Wikipedia

    en.wikipedia.org/wiki/Cut,_copy,_and_paste

    These are the standard shortcuts: Control-Z (or ⌘ Command + Z) to undo. Control-X (or ⌘ Command + X) to cut. Control-C (or ⌘ Command + C) to copy. Control-V (or ⌘ Command + V) to paste. The IBM Common User Access (CUA) standard also uses combinations of the Insert, Del, Shift and Control keys. Early versions of Windows used the IBM ...
