PID stands for Process Identifier, a uniquely assigned integer that identifies a process in the operating system. In any system, applications use PID to identify the process uniquely. Also, it is used in diagnosing the problems with the process in Multi-Tasking systems.

What is the proportional integral and derivative control system response?
The proportional integral and derivative control system or PID control system consists of proportionsl, derivative and integral elements which gives a very efficient process control.
How do you add text to an already existing p tag in JavaScript or PHP?
Consider your HTML <p id="pid">Hello </p> In javascript document.getElementById('pid').innerHTML="world"; Remember "id" are unique on the HTML page hence js will always pick <p> where id=pid.
What is a PID controller?
A proportional-integral-derivative controller(PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the error minimal.
When troubleshooting the problem scenarios during this lab which troubleshooting technique did you use primarily (top-down bottom-up or divide and conquer)?
Without knowing the problem scenarios it is impossible to know which troubleshooting technique you should have used. We can only answer questions that contain context. However, you are specifically being asked about which troubleshooting technique you personally used, not what technique you should have used, thus only you can actually answer the question. As such, this question adds no value.
How do you debug a program that is already running?
Assuming that you have written a program named abc.c and created executable abc. Steps: 1. run your program from command line ./abc 3. get the PID processid of the program from PS aux | grep abc 3. start the gdb from command line 4. type following command on GDB prompt (gdb) attach PID where PID = your program's processid got from step 1.
Why are PID numbers useful when you run processes in the backround?
Process ID numbers are useful for terminating and locating process names without it. It would be almost impossible for the operating system and the user to be able to terminate or control processes that are assigned within the kernel.
How would a bootable floppy disk be useful in troubleshooting?

How long should an IUD last before having pid?
IUDs do not cause PID. There are no health risks from leaving an IUD in place after its useful life, other than possible pregnancy in the case of a hormonal IUD.
Is child's PID and parents' PID identical?
No, every process gets its own PID. Otherwise, all PIDs would be the same, since every process is a child of some other process, all the way back to the init process (PID 1). The fork() system call will return the PID of the child to the parent, and will return 0 to the child. The child can find out its own PID with getpid(), and its parent PID with getppid().
