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.
Since Caml is a functional programming language, it is easy to create and pass around functions in Caml programs. This ability has very many applications. Calculating the numerical derivative of a function is one example. The following Caml function d computes the numerical derivative of a given function f at a given point x:
Individual machine languages are specific to a family of processors; machine-language code for one family of processors cannot run directly on processors in another family unless the processors in question have additional hardware to support it (for example, DEC VAX processors included a PDP-11 compatibility mode).
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] 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. [5]
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 are structurally similar to a processor's instructions. Generally, this refers to either machine code or assembly language. Because of the low (hence the word ...
This is an index to notable programming languages, in current or historical use. Dialects of BASIC, esoteric programming languages, and markup languages are not included. A programming language does not need to be imperative or Turing-complete, but must be executable and so does not include markup languages such as HTML or XML, but does include domain-specific languages such as SQL and its ...
[7] [8] Second generation languages represented a massive step away from the tradition of programmers conforming to the needs of a machine, and the first step towards the machine accommodating for the programmer, a phenomenon that would be repeated in all subsequent programming language generations. [2] [3]
The first generation of programming language is machine language. [45] Machine language requires the programmer to enter instructions using instruction numbers called machine code. For example, the ADD operation on the PDP-11 has instruction number 24576. [46] The second generation of programming language is assembly language. [45]
