Descriptor tables are data structures used in computer systems to store information about various system resources, such as memory segments or file descriptors, allowing for efficient resource management and access control. They play a crucial role in operating systems and hardware abstraction by organizing and maintaining metadata that helps in the translation of logical addresses to physical addresses and managing access permissions.
The Network Layer is responsible for data routing, packet forwarding, and addressing in a network, ensuring that data packets move from their source to their destination across multiple networks. It is a crucial layer in the OSI model that manages logical addressing and path determination, often using IP addresses and routing protocols to achieve efficient and reliable data transmission.
