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). Although decimal computers were once common, the contemporary marketplace is dominated by binary computers ; for those computers, machine code is "the binary representation of ...
In computer programming, assembly language (alternatively assembler language or symbolic machine code), often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions.
Computer programming. Computer programming or coding is the composition of sequences of instructions, called computer program|programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
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.
The first functioning programming languages designed to communicate instructions to a computer were written in the early 1950s. John Mauchly 's Short Code, proposed in 1949, was one of the first high-level languages ever developed for an electronic computer. [8] Unlike machine code, Short Code statements represented mathematical expressions in ...
A first generation (programming) language (1GL) is a grouping of programming languages that are machine level languages used to program first-generation computers. Originally, no translator was used to compile or assemble the first-generation language. The first-generation programming instructions were entered through the front panel switches ...
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.
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 ...
