What is the purpose of low level applications?

Low-level applications are designed to interact closely with hardware and system resources, providing essential functions like device management, memory management, and execution of system calls. They enable efficient operation of the hardware by allowing developers to write code that can directly manipulate system components. This level of control is crucial for performance optimization and resource management in operating systems, embedded systems, and real-time applications. Overall, low-level applications serve as the foundation for higher-level software by ensuring that the underlying hardware operates correctly and efficiently.
