PROGRAMMING LANGUAGES

WHAT IS THIS?

• A programming language is a type of written language that tells computers what to do. Examples are: python, ruby, jupiter, html, css, java, javascript, C, C++, and C#. Programming languages are used to write all computer programs and computer software.

HISTORY

The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax. Throughout the 20th century, research in compiler theory led to the creation of high-level programming languages, which use a more accessible syntax to communicate instructions.

Why do we use?

Programming languages allow us to translate the 1s and 0s into something that humans can understand and write. A programming language is made up of a series of symbols that serves as a bridge that allow humans to translate our thoughts into instructions computers can understand.

The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem.

PROGRAMMING LANGUAGES

JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user

Python is a general-purpose coding language—which means that, unlike HTML, CSS, and JavaScript, it can be used for other types of programming and software development besides web development.

CODING

SCRIPTING

The definition of coding is the process of creating instructions for computers using programming languages. Computer code is used to program the websites, apps, and other technologies we interact with every day. If you pay any attention to tech, you've undoubtedly heard the terms coding and programming dozens of times.The definition of coding is the process of creating instructions for computers using programming languages.

A scripting or script language is a programming language for a special run-time environment that automates the execution of tasks; the tasks could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted, rather than compiled. The term "scripting language" is also used loosely to refer to dynamic high-level general-purpose interpreted languages, such as Perl,[2] PowerShell, Python, and Tcl,[3] with the term "script" often used for small programs (up to a few thousand lines of code) in such languages, or in domain-specific languages such as the text-processing languages sed and AWK. Some of these languages were originally developed for use within a particular environment, and later developed into portable domain-specific or general-purpose languages.

GENERATIONS

Programming languages have been classified into several programming language generations. Historically, this classification was used to indicate increasing power of programming styles. Later writers have somewhat redefined the meanings as distinctions previously seen as important became less significant to current practice.First-generation languages are binary machine languages. Second-generation languages are machine-dependent assembly languages, and third-generation languages (3GLs) are high-level programming languages, such as FORTRAN, COBOL, BASIC, Pascal, C/C++ and Java.
