On Unix and Unix-like computer system operating systems, a zombie process or defunct process is a process that has actually finished execution (through the exit system call) however still has an entry in the process table: it is a process in the “Terminated state”. This happens for kid procedures, where the entry is still required to enable the moms and dad process to read its kid’s exit status: once the exit status is checked out through the wait system call, the zombie’s entry is gotten rid of from the process table and it is stated to be “gained”.
Running does not nevertheless suggest that the process is running, it represents that the process is either running or on the run line. Sleeping methods that the process is awaiting an occasion to finish (the sleep here is likewise often called interruptible sleep).

Since we do not understand exactly what occasion will happen next), the operating system keeps a different list for obstructed procedures (unordered.
A recently produced process is put at the back of the all set list, which is frequently called the run line (we will look at how this list is handled later on when we think about process scheduling). Considering that the information is not all set, the process is positioned in an obstructed state and another process is enabled to run. When the operating system finishes the read operation, the process is no longer obstructed and is put back on the run line
