In spite of the prevalence of high-level languages for the development of applications and software programs, the importance of low-level language in today’s world cannot be understated or ignored.
A programmer can still gain a lot if he or she can learn to code in machine level language and implement it in developing different programs. Any Programmer must have additional knowledge about the architecture of the particular machine, before programming in machine language. Low level language [LLL], are languages close to the machine level instruction set.
These instruction sets are a sequence of binary bits. They provide very less or almost no abstraction of the data from the hardware and can directly communicate with hardware devices. It consists of the set of instructions that run directly.
The most popular example of the low-level language is machine language and assembly language. A low-level programming language directly interacts with the computer memory. These days, it is possible to address critical issues concerning performance manipulate hardware directly, and also provide access to special instructions for processors.
The programs which are developed using the low level languages are dependent on machine and are not portable as the instruction written in low level language are machine dependent. The processor and the memory can be used by the user in a better way by using a low-level language.
As the low level language is machine friendly language it does not require any compiler or interpreter to translate the source to machine code there is no need of any compiler or translator to translate the source to machine code for the understanding of the machine. Thus, cuts the compilation and interpretation time.
An assembler translates the source code written in low-level language (binary bits) to machine code. Although it is difficult for programmers to write debug and maintain the low level program, it is fast and memory effective as it takes no time to execute.
We use the low level language to develop operating systems, device drivers, databases and applications that requires direct hardware access.
Low-level languages are used in coding device drivers, real-time systems, boot codes, reverse engineering and more. It is the language that a CPU recognizes however different CPUs recognize different types of them. When compared to high-level languages, which are mostly in the form of abstract data types, low level language is bare and transparent.
So, it is very helpful to the user for algorithm analysis, consisting of semantics and flow of control. As a whole, there is very less overhead as compared to high-level languages. High-level languages such as C, JAVA, BLISS, BCPL and many others include some degree of access to low-level programming functions. It is a programming language that provides little or no abstraction of programming concepts
Since the low level language is close to the computer hardware and constraints and many high level languages are related to the low level languages.
Similarly the low-level language is faster than the high level language. Hence it is important to have knowledge on the low level language to develop program.
