What is a programming language?

According to Wikipedia2, a programming language refers to various instructions, commands, and syntax necessary to develop a software program. Programming are categorized the following way:

High-Level LanguagesLow-Level Languages
The languages used by developers to create code are known as high-level languages. A developer’s code is then compiled to a low-level language’ that the computer hardware can readily identify and process.

High-level programming languages are generally easier to read and analyze, enabling developers to create source code with commonly used symbols and words naturally. Some examples of such terms used in high-level languages include designated words such as ifforwhilestring, or etc. Commonly used operators in these programming languages include symbols such as ==, <, and >. Most developers can understand many widely used high-level languages due to their similarity. 

Low-level languages encompass machine and assembly languages. An assembly language has a list of fundamental instructions and is generally more challenging to read than any high-level language. Assembly code can be translated to machine code with the use of an assembler. Machine code has a binary code set that a CPU can easily decipher. This type of code is not considered human-readable.
