What is Programming Language and its types.

Programming Language

A programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behaviour of a machine or to express algorithms.

The earliest known programmable machine preceded the invention of the digital computer and is the automatic flute player described in the 9th century by the brothers Musa in Baghdad, "during the Islamic Golden Age". From the early 1800s, "programs" were used to direct the behaviour of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. Many programming languages require computation to be specified in an imperative form (i.e., as a sequence of operations to perform), while other languages use other forms of program specification such as the declarative form (i.e. the desired result is specified, not how to achieve it).

Program

• Program is the nothing but it is the plan that contains the seat of instructions for fulfilling any specific job.
• Programming language are the languages that are used for communication between the programmer and computer system in the written way.
• Programming language is the language use to write the program.

There are two types of programming language

1. Low Level Programming Language:  Low Level Programming Language can directly interact with the hardware.
2. High Level Programming Language: High Level Programming Languages never interact with hardware. Directly rather interacts with the low level language.

Low Level Language: ------------------- System Software

High Level Language: ------------------ Application Software

Application Software can be of two types

1. Platform Dependent: 

• If any Application Software is dependent then it can only be onto the Platform for which it was developed.
•       If any software is developed for the windows operating system then can’t be run onto any other
        operating system.

      NOTE:- How any software becomes the platform dependent?

•      The compiler of the technology is either platform dependent or independent.
