1.汇编程序：
基本上是助记符的汇编语言，如GO，HALT，JUMP和NOT代码，这些语言通过编程语言转换器(即Assembler )转换为机器语言。汇编程序是一种程序，它将汇编语言作为源代码并将其转换为位格式，即计算机可以理解的机器语言。例如NASM和MASM。
2.口译员：
解释器是将高级语言转换为位格式(即机器语言)的程序。解释器和编译器的函数相同，但是解释器一次翻译一行并执行。没有产生目标代码，因此，每次必须运行程序时，都必须首先对其进行解释。
汇编器和解释器之间的区别：
| S.No. | Assembler | Interpreter |
|---|---|---|
| 1. | It converts low-level language to the machine language. | It converts high-level language to the machine language. |
| 2. | The program for an Assembler is written for particular hardware. | The program for an Interpreter is written for particular language. |
| 3. | It is one to one i.e. one instruction translates to only one instruction. | It is one to many i.e. one instruction translates to many instruction. |
| 4. | It translates entire program before running. | It translates program instructions line by line. |
| 5. | Errors are displayed before program is running. | Errors are displayed for the every interpreted instruction (if any). |
| 6. | It is used only one time to create an executable file. | It is used everytime when the program is running. |
| 7. | Requirement of memory is less. | Requirement of memory is more. |
| 8. | Programming language that it convert is Assembly language. | Programming language that it convert are PHP, Python, Perl, Ruby. |
