A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture, memory or underlying physical hardware; commands or functions in the language are structurally similar to a processor's instructions. These languages provide the programmer with full control over ...
A low-level programming language is one like assembly language that contains commands closer to processor instructions. In formal methods, a high-level formal specification can be related to a low-level executable implementation (e.g., formally by mathematical proof using formal verification techniques).
Software and hardware represent different levels of abstraction in computing. Software is typically written in high-level programming languages, which are easier for humans to understand and manipulate, while hardware implementations involve low-level descriptions of physical components and their interconnections.
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]
Programming in second generation languages may yield speed benefits, but several disadvantages have led to its decline: Programming is expressed in terms of individual processor instructions, rather than higher level logic. [2] [3] Low-level memory and hardware details must be manually managed which is often bug-prone. [2]

A first-generation programming language (1GL) is a machine-level programming language and belongs to the low-level programming languages. [1] A first generation (programming) language (1GL) is a grouping of programming languages that are machine level languages used to program first-generation computers.
Despite its low-level capabilities, the language was designed to encourage cross-platform programming. A standards -compliant C program written with portability in mind can be compiled for a wide variety of computer platforms and operating systems with few changes to its source code.
