What is programming Languages?

• A programming language is a set of words, symbols and codes that enables human to communicate with computers.
• It is a set of rules that provides a way of telling a computer what operations to perform
• It is a set of rules for communicating an algorithm
• It provides a linguistic framework for describing computations

Use of Programming Language?

• The programing language enables us to write efficient programs and develop online solutions such as- mobile applications, web applications, and games, etc. 
•  Programming languages are used to facilitate communication about the task of organizing and manipulating information, and to express algorithms precisely.

What are the types of programming language?

There are two types of programming languages, which can be categorized into the following ways:

1. Low level language

(a)  Machine language (1GL)

(b)  Assembly language (2GL)           

2. High level language    

(a) Procedural-Oriented language (3GL)

(b)  Problem-Oriented language (4GL)

(c)  Natural language (5GL)

1. Low level language :This language is the most understandable language used by computer to perform its operations.

It can be further categorized into:

a) Machine Language (1GL) : A first-generation programming language (1GL) is a machine-level programming language. This makes the language suitable for the understanding of the machine but far more difficult to interpret and learn by the human programmer.

b) Assembly Language : An assembly language is a type of low-level programming language that is intended to communicate directly with a computer’s hardware. Unlike machine language, which consists of binary and hexadecimal characters, assembly languages are designed to be readable by humans.

 2. High level language: A high-level language is any programming language that enables development of a program in a much more user-friendly programming context and is generally independent of the computer’s hardware architecture.

High level language can be further categorized as:

(a) Procedural-Oriented language (3GL): With a procedural language, often called a third-generation language (3GL), a programmer uses a series of English-like words to write instructions. While Programmers use an object-oriented programming (OOP) language or object-oriented program development tool to implement objects in a program.

(b) Problem-Oriented language (4GL): It allows the users to specify what the output should be, without describing all the details of how the data should be manupulated to produce the result. This is one step ahead from 3GL. These are result oriented and include database query language.

(c) Natural language (5GL): A fifth-generation programming language (5GL) is any programming language based on problem-solving using constraints given to the program, rather than using an algorithm written by a programmer. Most constraint-based and logic programming languages and some other declarative languages are fifth-generation languages.
