WebAddress space. In computing, an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device, disk sector, a memory cell or other logical or physical entity. For software programs to save and retrieve stored data, each datum must have an address where it can be located.

WebLinux uses a different implementation for threads. The basic unit is called a task (hence the struct task_struct) and it is used for both tasks and processes. Instead of embedding resources in the task structure it has pointers to these resources. Thus, if two threads are the same process will point to the same resource structure instance. WebThe address space operations are used to map parts of files into pages in Linux's page cache. This page cache represents data on some physical device (like a disk) that has been mapped into memory. The physical devices usually corresponds to a disk, but need not necessarily do so. This is the structure of a page (note the existence of a mapping ...
