Difference between assembler and compiler
Introduction
Although they are terms that are commonly used in programming, many people do not know exactly what an assembler is and what a compiler is. In this article, we will explain the difference between the two.
Compiler
A compiler is a program that translates source code written by the programmer in a high-level language into machine language, which is the language that the computer understands. The compilation process includes several stages such as lexical analysis, syntactic analysis, semantic analysis and object code generation.
The compilation result is an object file that cannot yet be directly executed by the computer. Instead, the object file must be linked with other libraries to produce an executable file.
Compiler Advantages
- Compiled code runs faster than interpreted source code.
- Syntax errors are detected before program execution.
- The code can be optimized to improve its performance.
Assembler
The assembler is a program that translates assembly code into machine language. Assembly code is another programming language that is similar to machine language, but is easier for humans to understand and write.
The assembly process includes a single stage, code generation. The result of the assembly is an object file that can be linked with other libraries to produce an executable file.
Advantages of the assembler
- Assembled code runs faster than compiled code.
- A greater level of control is possible in code generation.
- It is possible to directly access registers and memory Computer.
Conclusion
In summary, the main difference between an assembler and a compiler is that the assembler translates assembly code into machine language, while the compiler translates code from a high-level language into machine language. They both have their advantages and disadvantages, and the choice of one or the other will depend on the project and the programmer's objectives.
