Question

The symbols used in an assembly language are :

• A. Mneumonics
• B. Codes
• C. Assembler
• D. All of the above

Answer 1

Answer:

A. Mneumonics

• Assembly language is a low-level programming language that uses symbolic representations instead of binary code (0s and 1s) to make programming more human-readable. The symbols used in assembly language are called mnemonics.

• What are Mnemonics?

• Mnemonics are memory aids or symbolic names that represent machine language instructions. Instead of writing complex binary codes, programmers use simple, meaningful abbreviations that are easier to remember and understand.

• Examples of Mnemonics in Assembly Language:

  • MOV - Move data from one location to another

  • ADD - Add two values

  • SUB - Subtract one value from another

  • JMP - Jump to a different part of the program

  • CMP - Compare two values

• Why Mnemonics are Used:

  1. Easier to Remember: "ADD" is much easier to remember than its binary equivalent

  2. Reduced Errors: Symbolic names reduce the chance of making mistakes

  3. Better Readability: Code becomes more understandable for humans

  4. Simplified Programming: Makes assembly language programming more accessible

• The Assembly Process:

  • When a programmer writes assembly code using mnemonics, a special program called an assembler converts these mnemonics into machine code (binary) that the computer can execute.

  • Therefore, mnemonics are the fundamental symbols that make assembly language a practical bridge between high-level programming languages and machine code.
