  • What is 6502 assembly?

    6502 assembly is a very low-level language that works specifically for the 6502 microprocessor — a very popular processor from the 1970s. We will begin by taking a closer look at what assembly exactly is and why we have chosen to spend time learning a variant of it that is almost 50 years old.

  • What is difference between assembly language and machine language?

    Assembly language is only understand by human beings not by the computers. In machine language data only represented with the help of binary format(0s and 1s), hexadecimal and octadecimal. In assembly language data can be represented with the help of mnemonics such as Mov, Add, Sub, End etc.

  • Can assembly language run on any machine?

    Because assembly depends on the machine code instructions, each assembly language is specific to a particular computer architecture. Sometimes there is more than one assembler for the same architecture, and sometimes an assembler is specific to an operating system or to particular operating systems.
  • Assembly language is a low-level computer programming language. Its instructions are short mnemonics, such as ADD, SUB (subtract), and JMP (jump), that match machine language instructions. An assembler converts assembly language into machine language. A disassembler converts machine language into assembly.
