Low-level VS High-Level VS Middle-level Programming Languages – What's The Difference?

 

           Low-level, high-level, and middle-level languages are the three categories of programming languages. Assembly language and machine language, commonly referred to as binary, are examples of low-level languages. There is very little to no abstraction from the computer's hardware offered by any language. Specific machine instructions and language instructions are intimately related or correspond to one another. Because of this "closeness to the machine," the computer can operate faster, more effectively, use less memory, and have more precise hardware control.

         The lowest level of programming languages is called machine language. The instructions are made up of a sequence of 0s and 1s that match the instructions and memory locations of a specific machine. Additionally, the CPU of the computer immediately executes instructions. Despite being the preferred language for building programs in the early days of computing, machine language is difficult to read by humans and requires a lot of effort to develop.

        Programmers can interact with machines more closely and at a somewhat higher level thanks to assembly language. Rather than employing a series of 0s and 1s, it makes use of mnemonics and symbols that directly match the instruction set of a certain machine.

        Next, a given machine architecture's instruction set is very different from high-level languages like Python and JavaScript.They are simpler to work with and comprehend because their grammar is similar to that of the English language. High-level language programs are also machine-independent and portable. In other words, a program can execute on any platform that recognizes that language. Nevertheless, because of their abstract nature, they often require more memory, operate more slowly, and make it more difficult to interface with low-level hardware and systems.

        Last but not least, middle-level programming languages serve as a link between high-level and low-level languages, such as C and C++. They permit intimacy and some degree of hardware control. They also provide a level of abstraction that makes it easier for programmers to construct instructions that are more legible by humans.
