Why is assembly code different on every type of CPU?

The main differences between the assembly languages will be the set of operation codes (usually called opcodes) the assembler recognizes, and the format of the operand fields. But there may be even more than one assembler “type” for the same processor.

Why do hackers use assembly language?

Knowing assembly will help you to understand how the attack works, and will allow you to craft the “payload” code to be injected. Low level knowledge about the inner workings of function casks and memory management on a variety of systems may allow you to discover such vulnerabilities in the first place.

Is there more than one assembly language?

There are many, many types of assembly languages. The current most popular are ARM, MIPS, and x86. x86 assembler is used on Intel PCs. Each flavor has different versions which span the gammut from 16-bit to 64-bit instructions.

What is the assembly language program?

The assembly language program is based on the instruction set defined for a specific MCU, plus assembler directives which control the conversion to machine code, but are not part of the final program. The instruction syntax is similar for all PIC chips, but the larger, more powerful chips tend to have more instructions.

Why don’t we have one assembly language for all computers?

There is no conceptual (I daresay, no computer science) reason against having one assembly language for all computers in the world. In fact, that would make many things much easier. As far as theory is concerned, they are all the same, anyway, up to some funky bijection.

How many different types of assembly language are there?

there must be at least one completely different assembly language for each different type of CPU (because assembly language is directly related to machine code). for each of those there may be 2 or more categories of assembly language (e.g. “Intel syntax” vs. “AT syntax”).

Do Different assemblers for the same CPU have different syntax?

Different assemblers (e.g. Gnu’s and Microsoft’s) for the same CPU may have different assembly language syntax; but the difference is trivial, because they’re both targeting the same CPU, and there’s a 1-to-1 mapping (if you ignore macros) between assembly instructions and CPU opcodes.
