machine language and assembly language and high level language

Assembly language is print artist platinum 4.5 serial number a symbolic representation of machine code, which allows programmers to write programs in machine code without having to deal with the long binary strings.
Machine languages generally consist of strings of numbers (ultimately reduced to 1s and one piece episode 572 english subbed 0s) that instruct computers to perform their most elementary operations one at a time.Programmers write instructions in various programming languages, some directly understandable by computers and others requiring intermediate translation steps.Machine languages generally consist of strings of numbers (ultimately reduced to 1s and 0s) that instruct com-puters to perform their most elementary operations one at a time.In this book, we study several key programming languages, including JavaScript, ActionScript, PHP and Ruby on Railseach of these scripting languages is processed by interpreters.Also called machine code.The compiler figures out how to generate machine language that does exactly what the high-level-language source program specifies.High-level programming languages must be translated into machine code for execution, and this process is called compilation.Languages like C, Algol, cobol, etc., are all compiled high-level languages.Any computer can directly understand only its own machine languagethe "natural language" of a computer that is defined by its hardware design.All of the Internet and web application development languages that youll learn in this book are high-level languages.We also study markup languages such as xhtml and XML, which can be processed by inter-preted scripting languages.Page 8, high-Level Languages.Instead of using the strings of numbers that computers could directly understand, programmers began using English-like abbreviations to represent elementary operations.This means that they are not translated into machine code.




Machine lan-guage is the natural language of a computer and as such is defined by its hardware design.Machine languages are machine dependent (i.e., a particular machine language can be used on only one type of computer).Machine code is different for each type of computer.Interpreters are also popular with so-called scripting languages on the Web.Visual Basic, Java, Javascript, basic, and many other languages work this way.A simple assembler program translates this symbolic language directly into machine code.A program in machine code for an Intel x86-based PC will not run on an IBM mainframe computer, and vice versa.Translator programs called assemblers were developed to convert early assembly-language programs to machine language at computer speeds.
For example, the machine code for an instruction that adds two numbers might be 01101110, but in assembly language, this can be represented by the symbol ADD.
