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 binary language that computers understand. Examples of low-level languages include Assembly language and machine code. These languages allow programmers to write instructions that directly manipulate the computer's memory and processor. Because low-level languages are closely tied to hardware, they can be more efficient and faster than high-level languages. However, they are also more complex and harder to read, making them less user-friendly. Programmers often use low-level languages for tasks that require high performance, such as operating systems and embedded systems.
