resources with other processes. Each thread has a unique task_struct of its own, so in the kernel it looks like a normal process.5. Process terminationProcess finalization most of the work is done by the do_exit () function, and it does the following things:At this point, all resources associated with the process are freed (assuming the process is the only consumer of those resources). The process is not operational and is in a Task_zombie state. All of the resources it occupies are kernel stac

The main goal of capacity planning is to determine the requirements of system resources, design a balanced system, and optimize resources to achieve the best performance and throughput to meet business needs. When we discuss database scale adjustment and capacity

In the object relationship model, we know there are three relationships: one-to-one, one-to-many, and many-to-many. This is only a conceptual relationship, but in a real relational database, we only have foreign keys, and there are no such three relationships, so let's talk about it in the relational database management system, how to implement these three relati
