Description: Hardware resource management refers to the process of allocating and controlling the physical resources of a computer system, such as the CPU, memory, storage, and input/output devices. This management is crucial for ensuring optimal performance and efficient utilization of available resources. The operating system acts as an intermediary between the hardware and applications, facilitating communication and ensuring that each process has access to the necessary resources without interfering with others. Resource management is carried out through various techniques, such as process scheduling, memory management, and device allocation. In kernel mode, the operating system has full access to hardware resources, allowing for more direct and efficient management. On the other hand, in user mode, applications operate with restrictions to protect the integrity of the system. This duality is fundamental for the stability and security of the operating environment. The system architecture also plays an important role, as it defines how resources are organized and managed, directly affecting system performance and scalability. In summary, hardware resource management is an essential component in operating system administration, ensuring that resources are used effectively and efficiently.
