What is the primary purpose of a low-level language?

The primary purpose of a low-level language is to offer direct control over hardware and system resources. Low-level languages, such as assembly language or machine code, are much closer to the hardware than high-level languages. This proximity allows programmers to write instructions that directly manipulate memory addresses, registers, and specific processor commands.

This level of control is essential in scenarios where efficiency and performance are critical, such as in operating systems, embedded systems, or performance-critical applications where resource management is crucial. By utilizing low-level languages, developers can optimize code for speed and memory usage, which is often not possible in higher-level languages that prioritize ease of use and abstraction over direct hardware manipulation.

In comparison, the other options focus on different aspects of programming and user experience but do not align with the core capabilities of low-level languages. For instance, improving user interface design is typically associated with high-level languages that focus on user-friendliness, while high-level abstractions and simplifying internet application development are characteristics associated with modern programming languages that provide libraries and frameworks to simplify complex tasks.
