what is compiler

A compiler is a software tool that translates high-level programming languages into machine code that can be executed by a computer. It takes the source code written by a programmer and converts it into a set of instructions that can be understood and executed by the computer’s processor. This process is known as compilation. Compilers are essential for software development as they enable programmers to write code in a more human-readable form and then have it translated into the machine language that the computer can understand and execute.

what is assembler

Assembler is a type of computer program that translates assembly language code into machine code that can be executed by a computer’s processor. Assembly language is a low-level programming language that is specific to a particular computer architecture.

Example:
Here is an example of a simple assembly language program that adds two numbers:

“`
section .data
num1 db 10
num2 db 20

section .text
global _start

_start:
mov al, [num1]
add al, [num2]
ret
“`

Advantages of using an assembler:
1. Assembler programs are faster and more efficient than programs written in higher-level languages.
2. Assembler allows for direct manipulation of hardware resources and registers.
