Low-level languages are programming languages that provide little abstraction from a computer's hardware. They are closely related to machine code, which is the set of instructions executed directly by a computer's CPU. Examples of low-level languages include Assembly Language and C, which allow programmers to write code that interacts directly with the system's memory and hardware components. These languages are often used in system programming, embedded systems, and performance-critical applications. While they require a deeper understanding of computer architecture, they offer greater control and efficiency compared to high-level languages, making them essential for tasks that demand precise hardware manipulation.
