What do you mean by programming languages? What is the difference between machine language, assembly language and high-level language?

programming language: is a formal language comprising a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement algorithms.

Machine language: is the low level programming language and it represented by 0s and 1s.

Assembly language: is in between low level and high-level language so it is intermediary language. It uses numbers, symbols, and abbreviations instead of 0s and 1s.

High-level language: is a programming language such as C, FORTRAN, or Java that enables a programmer to write programs that are more or less independent of a particular type of computer. Also they are closer to human languages and further from machine languages.
