Next Step


So, these were the basic instructions of the microprocessor instruction set of the x86 family..

There are about 20,000 instructions in the instruction set, I would share with you the rest of instructions but firstly  we would have a quick overview of the Assembler Directives..

What is an  Assembler..? What is the use of it.? And why do we need an assembler..?


  • An assembly language is a low-level programming language for computers, microprocessors, micro-controllers and other programmable devices. 
  • A utility program called an assembler is used to translate assembly language statements into the target computer's machine code.
  • The assembler performs a more or less isomorphic translation (a one-to-one mapping) from mnemonic statements into machine instructions and data. This is in contrast with high-level languages in which a single statement generally results in many machine instructions.
  • We would be using a Turbo Assembler TASM in short. You could find it on the Google
