However, for a computer to understand and run a program created with a high-level language, it must be compiled into machine language. What is Low Level Language ? Thes e languages allow for quick iteration, incremental improvements, and code portability, which are critical to the software engineer. in the form of 0 and 1. It is also an advanced computer programming language. That is, unlike low-level languages like assembly or machine language, high-level programming can amplify the programmer's instructions and trigger a lot of data movements in the background without their knowledge. I assumed this was pretty much standard English when heard elsewhere on different subjects. In machine level language computer only understand digital numbers i.e. In general, high level languages share many common features 1. However, the computer cannot understand them and they need to be translated into machine language with the help of other programs known as Compilers or Translators. Although code might seem hard to understand to non-programmers, it is much clearer and easier to read than low level languages. Machine Language. What is High Level Language?
