🚀 Bridging Applications to Hardware: OS Offerings and Programming Synergy

Programming abstraction or interfaces provided by the operating system (OS) are essential components that allow application programs to interact with the underlying hardware and resources of a computer system without needing to understand the low-level details. These abstractions simplify the development process, enhance portability, and improve system stability. Here are some common programming abstractions and interfaces provided by operating systems:
