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 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.
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.
Machine code is a strictly numerical language, and it is the lowest-level interface to the CPU intended for a programmer. Assembly language provides a direct map between the numerical machine code and a human-readable mnemonic. In assembly, numerical opcodes and operands are replaced with mnemonics and labels.
C is often used in low-level systems programming where escapes from the type system may be necessary. The compiler attempts to ensure type correctness of most expressions, but the programmer can override the checks in various ways, either by using a type cast to explicitly convert a value from one type to another, or by using pointers or unions ...

Language for communicating instructions to a machine The source code for a computer program in C. The gray lines are comments that explain the program to humans. When compiled and run, it will give the output "Hello, world!". A programming language is a system of notation for writing ...
From this low-level perspective, the program state is defined by the contents of memory, and the statements are instructions in the native machine language of the computer. Higher-level imperative languages use variables and more complex statements, but still follow the same paradigm.
