Assembly Language Definition

Assembly Language – a low-level programming language that expresses the processor instructions in human-understandable form. Programs in assembly language are unambiguously translated into the instructions of some particular processor, and generally, it cannot be ported without significant modification to make it run on a machine with a different instruction system.

Assemblers provided a great relief to the early computer programming task, but with time, it became clear that the magnitude of the application tasks dictated the use of high-level languages. Significance of the assembler fell with mainframes and minicomputers starting to perform, development of languages such as C; then, again grew up with microcomputers since quality compilers of high-level languages weren’t available from the outset.

But already at the beginning of the XXI century, growing computer performance was complemented by optimizing compilers capable of generating more optimal machine code than an average programmer is capable of. Also, more actual became a question of portability between platforms.
