What is High-Level Programming Language? Webopedia Definition
Computer dictionary definition for what assembly languages means there is ( nearly) a one-to-one relationship between what it tells the computer to do, High -level languages provide abstractions of low-level operations. High level languages have a one to many relationship with assembly source programs can be compiled and run on a wide variety of computer systems is said . Learn the difference between high level & low level languages through our article and other places which I like the best- low level or high level programming. and if you show them some programs written in assembly, then will probably go.
Layers of Programming: Machine, Assembly, & High Level Languages - The Revisionist
So that if you wanted to give a computer an instruction in its native or Machine language, you have to manually enter the instructions as binary code. For example, adding two numbers together in machine language would look like this: For these reasons, Assembly language was developed as an alternative to Machine language.
Assembly Language uses short descriptive words mnemonic to represent each of the Machine Language instructions. For example the mnemonic add means to add numbers together, and sub means to subtract the numbers. So if you want to add the numbers 2 and 3 in assembly language, it would look like this: However, the computer cannot directly execute the assembly language. First another program called the assembler is used to translate the Assembly Language into machine code. What is a High-Level Language?
High-Level Languages are English like and therefore easier to learn and use.
Layers of Programming: Machine, Assembly, & High Level Languages
Note that instructions in a High-Level Language are called statements. Note that a program written in a high-level language is called the source code.
Why is ASM a "low-level" language? Assembly is called a low-level programming language because there is nearly a one-to-one relationship between what it tells the computer to do, and what the computer does. In general, one line of an assembly program contains a maximum of one instruction for the computer.
How is ASM different from a "high-level" language? High-level languages provide abstractions of low-level operations which allow the programmer to focus more on describing what they want to do, and less on how it should be done. Programming this way is more convenient and makes programs easier to read at the sacrifice of low-level control. Programs written in high-level languages will never match the raw speed and efficiency of programs written in assembly.
What is a "mid-level" language? Mid-level or lower-level languages provide some high-level abstractions to make the programmer's life easier, while still providing access to low-level operations. They are often used to write operating systemsso they are sometimes called system programming languages.
Programs written in mid-level languages can perform as well, or nearly as well, as programs written in assembly language. Because assembly languages are tied to one specific computer architecture, they are not portable. A program written in one assembly language would need to be completely rewritten for it to run on another type of machine.Assembly Language Visual Studio Tutorial: Introduction - Relation with Machine Language
Portability is one of the main advantages of higher-level languages. The C programming language is often called "portable assembly" because C compilers exist for nearly every modern system architecture. A program written in C may require some changes before it will compile on another computer, but the core language is portable.
