A computer is an electronic device that performs operations based on instructions.
These instructions must be in a form that the computer’s processor can understand.
That form is known as Machine Language, which consists of binary code — a series of 0s and 1s.
Machine language is the lowest-level programming language and is directly executed by the computer’s CPU.
All high-level programming languages must be translated into machine language using a compiler or interpreter before the computer can execute the instructions.
Hence, a computer can understand only machine language.
