It's a pretty much common question asked in most of the interviews related to Linux, and most of the time people got it confused with Orphan Process. But these two are totally different from each other. A Zombie Process is nearly the same thing which we see in lot of horror movies. Like the dead people which don't have any life force left, Zombie processes are the dead processes sitting in the process table and doing nothing.

To explain this in much better way, "Zombie process or defunct process is a process that have completed the execution, have released all the resources (CPU, memory) but still had an entry in the process table."

Also, apart from sending the emails, sometimes one needs to test or debug the email server which can't be done by traditional email clients. If you are one of those system administrators and are scared, then you shouldn't be, because this is where netcat comes to rescue.

Upgrading the system is one of the very common tasks a Linux Administrator usually do. One can easily update the system with Yum or apt-get commands but the main problem which everyone faces is to reboot the system after a kernel upgrade.
