However, if the parent process lingers in collecting the child's data (or fails to do it at all), the system has no option but keep the child's pid and termination data in the process table indefinitely. Such a terminated process whose data has not been collected is called a zombie process, or simply a zombie, in the UNIX parlance. The name is ...
In some APIs, PID 0 is also used as a special value that always refers to the calling thread, process, or process group. [3] [4] Process ID 1 is usually the init process primarily responsible for starting and shutting down the system. Originally, process ID 1 was not specifically reserved for init by any technical measures: it simply had this ...
The child process can then overlay itself with a different program (using exec) as required. [1] Each process may create many child processes but will have at most one parent process; if a process does not have a parent this usually indicates that it was created directly by the kernel.
In mathematics, in the field of abstract algebra, the structure theorem for finitely generated modules over a principal ideal domain is a generalization of the fundamental theorem of finitely generated abelian groups and roughly states that finitely generated modules over a principal ideal domain (PID) can be uniquely decomposed in much the same way that integers have a prime factorization.
The context-input-process-output (CIPO) model is a basic systems model of school functioning, which can be applied to several levels within education, namely system level, school level and classroom level. [1] The model also functions as analytical framework through which the educational quality can be reviewed. [2]
An operating system may provide variations of the wait call that allow a process to wait for any of its child processes to exit, or to wait for a single specific child process (identified by its process ID) to exit. Some operating systems issue a signal to the parent process when a child process terminates, notifying the parent process and ...
In terms of policy, this view sees curriculum frameworks as tools to bridge broad educational goals and the processes to reach them. A humanistic curriculum development perspective holds that for curriculum frameworks to be legitimate, the process of policy dialogue to define educational goals must be participatory and inclusive.

Instructional scaffolding is the support given to a student by an instructor throughout the learning process. This support is specifically tailored to each student; this instructional approach allows students to experience student-centered learning, which tends to facilitate more efficient learning than teacher-centered learning.
