Explain the Resource Ownership and Control
Operating systems are required to handle many different types of resources. CPU , memory, and I/O devices are some of the varied system resources the OS must balance between running applications. As applications make requests of system resources, they are granted access (either exclusive or shared). As we have learned in the previous sections, each operating system provides this allocation and ownership in a slightly different manner.
Resources all allocated to the applications are generally either associated with the process or the thread that requested them. Access to these items outside of the original process or threads may be granted through inheritance or common sharing of information. Since the core design decisions vary between operating systems, it is therefore necessary to compare resource ownership on a per-platform basis. Resource ownership and control is a significant issue facing developers today.
