a computers native tongue is binary.a language made out of two numbers, one and zero.For humans it is hard to comprehend binary language that is why we need a programming language.
programming languages are like bridges, allowing us to translate our thoughts into structures computer can understand using a specific human readable language.
programming languages fall into two classifications , low level and high level, low level languages are closer to binary language , and they are faster compared to high level languages.
high level languages are closer to how humans communicate, using words that are closer to human language.their downside is that they take longer ,compared to low level languages, to be translated to machine code for computers to understand.
As computers are getting more powerful the difference in runtime between low-level and high level-language is often only milliseconds.
