 what is programming language You must appreciate the fact that programming languages ​​are created by us humans. These languages ​​are used to communicate instructions to machines, especially computers, so that programs can control the behavior of the machines' hardware to achieve the desired results.  Basically, the hardware of the computer understands only the language of the hardware which is called as machine language. The hardware is unable to understand and understand a program written in another programming language. In addition, each type of CPU has its own machine language. Therefore, in order for the computer's hardware to understand the instructions contained in a program written in another programming language, a mechanism is needed, called a 'translator'. It converts programs written in programming languages ​​other than the native machine language of the CPU (hardware) into the native machine language of a particular CPU on which this program is intended
