The right term is not вЂassembly languageвЂ™ but вЂassembly languagesвЂ™, as there are a number of programming languages that fall under this category.

You need to have a clear understanding about registers, primary memory, processors, etc, to write a decent assembly language program.ДЄccording to Wikipedia, вЂњA program written in assembly language consists of a series of mnemonic processor instructions and meta-statements (known variously as directives, pseudo-instructions, and pseudo-ops), comments and data.вЂќ Now, before we proceed any further, I would like to clarify an important point. If you learn assembly language programming, things will change. At the same time, if you are a serious programmer, it is a good idea to know what is happening inside the machine when the code you write is executed. Of course, this is really a nice feature of high-level languages. A high-level language programmer can write thousands of lines of code without caring the least about the underlying architecture of the hardware. Third, learning assembly language programming will enhance your knowledge of computers in general.

So embedded system programming still involves a lot of assembly coding. The microchips in our washing machines and cars do not have huge memories or powerful processors. But donвЂ™t assume all the systems in the world have huge amounts of resources available. Does it make assembly language programming less attractive? Maybe a bit. Nowadays, even laptops have gigabytes of RAM and processors have gigahertz of speed. In the earlier days, when resources like memory and processor speed were limited, this was a great advantage. Assembly language code can run very fast as there is one less translation to machine code when compared with high-level languages. Essentially, when you are programming on вЂbare metalвЂ™ (when you are accessing the hardware directly), you still need some assembly coding, whatever the application may be. For example, code optimisation phase of compilers often involve assembly coding. Assembly programming is also used in certain phases of compilation.

For example, while writing device drivers for a machine, programmers often rely on assembly coding. But certain parts of the kernel of the operating system are still written in assembly language. Of course, nowadays, a lot of this code is written in high-level languages like C, C++, etc. Assembly language is used while designing operating systems and compilers. Second, it is widely used in the industry. This language is also notorious for its steep learning curve.) (But I do not want to misrepresent facts, as assembly language is also featured in the list of the most dreaded languages - in fact, itвЂ™s ranked 4th here. The Stack Overflow Developer Survey 2020 ranked the assembly language 17th among the most wanted programming languages. First, it is still popular and ranks among the top 20 in the TIOBE index.

If you plan to make programming your career, it is a good idea to learn a programming language like assembly language at some stage.

This article focuses on assembly language programming in Linux, which figures at number 17 on the TIOBE index. One often comes across a lot of ads encouraging children to learn programming, which can be a very useful skill to have these days.
