How does a compiler converts high level programming language into assembly?
In the “classical” model, the compiler converts high level code to assembly, the assembler assembles it to machine code that gets stored into object files, which then are linked to generate an executable file.
Why does assembly language run faster than high-level language?
The hand written assembly language programs are faster and use less memory than the programs with the same features, but written in high level languages (HLL). Fortunately, the assembly language programmer, does not need to compete with the compiler in the platform specific optimizations, in order to beat it.
Is there any compiler for assembly language?
A Compiler is primarily used for programs that translate source code from a high-level programming language to a machine level language to create an executable program….Difference between Compiler and Assembler:
| Compiler | Assembler |
|---|---|
| C, C++, Java, and C# are examples of compiled languages. | GAS, GNU is an example of an assembler. |
What were the assembly language and high level programming language?
Assembly language may itself be regarded as a higher level (but often still one-to-one if used without macros) representation of machine code, as it supports concepts such as constants and (limited) expressions, sometimes even variables, procedures, and data structures.
Where is assembly language used today?
Today, assembly language is still used for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.
How is high level language converted to assembly language?
High-level compilers do not convert source code into assembly language. Rather, they convert it into object code/machine code directly. Assembly language is a human-readable version of object/machine code, designed for a programmer.
Can a compiler convert high level code into machine code?
This is a very general question (and also a bit difficult to understand, to be honest). A compiler for a high-level language could convert high level code into assembler and a secondary utility could convert assembler into what you call machine code. A compiler could also produce machine code directly.
Why is a compiler called a pre processor?
Compiler is a program because it converts source code or language into target code or language where source code can be High Level Language but Target code should be lower than Source code because if the level of both become same than it is called a pre-processor.

Is it useful to read high level assembly?
That said, assembly is one step away from being “machine code”, so it is often useful to be able to read it to determine what the compiler has done. Sometimes this will lead to insights that allow one to optimize the high level code; other times, a 1337 programmer might opt to edit the assembly by hand.
