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).
Low-level memory and hardware details must be manually managed which is often bug-prone. [2] Programs are machine-dependent, so different versions must be written for every target machine architecture. [3] The vast majority of programs are written in a third-generation programming language or a fourth-generation programming language.
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.
An assembler program functions by converting low-level assembly code into a conventional machine code that is readable by the CPU. The purpose of assembly language, like other coding languages, is to make the programming process more user-friendly than programming in machine language.
To prove that operational semantics over a high-level machine is related by a simulation with the semantics over a low-level machine, whereby the low-level abstract machine contains more primitive operations than the high-level abstract machine definition of a given language. Such a proof demonstrates that the low-level machine "faithfully ...

Image analysis is a typical domain for which a high degree of abstraction from low-level methods is required, and where the semantic gap immediately affects the user. If image content is to be identified to understand the meaning of an image, the only available independent information is the low-level pixel data.
