programming language

1-: A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer Programming languages can be used to create programs to control the behavior of a machine or to express algorithms. 2-: A vocabulary and set of grammatical rules for instructing acomputer to perform specific tasks. The termprogramming language usually refers to high-level languages, such as BASIC,C, C++, COBOL, FORTRAN, Ada, and Pascal. Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions. High-level programming languages, while simple compared to human languages, are more complex than the languages the computer actually understands, called machine languages. Each different type of CPUhas its own unique machine language.

internet

Internet The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents andapplications of the World Wide Web (WWW),electronic mail, telephony, and peer-to-peernetworks for file sharing

low level language

Low level language
-:

In computer science, a low-levelprogramming language is a programming language that provides little or no abstraction from a computer's instruction set architecture—commands or functions in thelanguage map closely to processor instructions. Generally this refers to either machine code or assemblylanguage.

high level language

High level language
-:A programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Suchlanguages are considered high-levelbecause they are closer to humanlanguages and further from machinelanguages.
