Is it important to learn assembly 8086?

But to be able to know that, you have to learn real assembly. 8086 will not help you with that. That’s something completely different to the stuff we are doing today. You’ll need that as urgent as VAX, PDP-11, MC680x0, MOS6502, Z80 and all the other fine old crap assembly languages. What is relevant today is x86_64, ARM, ATMEL/AVR, mainly.

How to learn assembly language?

How To Learn Assembly Language? A functional assembler must first be installed. You will need to write assembly code for the second part. The third step is to assemble the code. The fourth step is to run it. Every time you do so, repeat.

Is assembly language a platform specific language?

Programmers can understand the assembly language, however, CPU cannot. CPU can directly understand Machine language. No need of compiler or assembler. Assembly language is a set of instructions which are the same irrespective of platform. Machine code differs platform to platform. The codes and instructions of assembly language can be memorized.

Is assembly language dangerous?

What is Assembly Language? One step up from machine byte code Uses mnemonic instructions to explain itself. Very simple and straightforward rules. – powerful and dangerous all at the same time... Firm rules but think of it like a game, once you learn the rules it's pretty straightforward.
