Execution speed is defined as speed of carrying out and completing a task or command or instruction in a cycle. Execution speed of machine or assembly language is rapid among all other language.
Instructions are received from central processing unit (CPU) directly to execute it , thus fastest execution is processed .
As for high level language and other languages,they are converted into machine language so that it can be understood by system to execute instruction.
The execution speed of machine language is faster than the execution speed of other languages. Machine or assembly language will execute the fastest as compared to high-level languages. No other language can execute faster than Machine language since instructions are directed straight to the CPU. Other high-level languages often add some non-zero amount of overhead to the execution time, thus, causing some delay.
