Examples of low-level languages are assembly and machine languages. A low-level language is a programming language that deals with a computer’s hardware components and constraints. Low-level languages directly operate and handle a computer’s entire hardware and instructions set architecture.
They are often described as machine-oriented languages or being close to the hardware. Programs and applications written in low-level language require no interpretation, and they are directly executed on the computing hardware.
An assembly language is a group of languages that implements a symbolic representation of the machine code required to program certain CPU architecture. It is a programming language for microprocessors and other programming devices, and it is the most basic programming language available for any processor. Generally, assemblers produce object files, and most provide macros. Unlike high-level languages, assembly languages lack variables and functions, but they have the same structure and set of commands, much like machine languages. This programming language is helpful to programmers when speed is required and when they need to perform an operation that cannot be done in high-level languages.
Machine language is a programming language that can be directly understood by a computer without interpretation. It is also referred to machine code or object code. If a program is written in a high-level language such as Java or C, the program is translated into machine language by an assembler, compiler or interpreter.
