itselfexecution

itselfexecution is a term that refers to a process or program that can initiate its own execution or cause another instance of itself to run. This is distinct from external processes that might launch a program. In essence, a program is responsible for its own or a copy of its own subsequent invocation. This can occur through various mechanisms, such as self-replication, recursion, or by directly calling an operating system function to start a new process that loads the same executable.

One common scenario where itselfexecution is relevant is in the study of computer viruses or self-replicating malware. These programs are designed to copy themselves and spread, effectively executing themselves on new systems. Another context is in certain types of concurrent programming or distributed systems where a process might need to spawn worker processes that are identical to itself to handle tasks in parallel. Recursive algorithms also exhibit a form of itselfexecution, where a function calls itself, although this is typically within the same process's execution stack rather than launching a new, independent process instance. The precise implementation of itselfexecution depends heavily on the programming language and the underlying operating system. It often involves inter-process communication or system calls to manage the creation of new processes.
