The closest Linux equivalent is the task_struct; however, that's only used inside the kernel. It's not exported to userspace. All information on running processes on Linux is exposed via procfs, which is mounted at /proc. See man proc for details on what's available and where. run by the kernel. On a context switch , a task's context is saved in the Task Control Block (TCB).
