What is the importance of a ground plane of a PCB?

I find that the all types of PCB samples from my suppliers have ground planes. It seems important and I want to know about its function.

Very important. Once the signal gets into the ground plane from the circuit, there will be a ripple. Ripple may spread and influence the signal in other circuits.
If we don’t have a ground plane, the ripple will last longer and may influence other circuits nearby.

Why do some through-hole LEDs have flared leads?

I have worked with many through-hole LEDs over the years. I ordered a bunch for a personal project. I did not notice they have flared leads until I used them. I’ve never encountered these flared leads before. What is their purpose?

Does each process have its own PCB or there is just one?

To my understanding, each process in the operating system contains its own separate Process Control Block. Can someone explain this to me. Does each process have its own PCB or is there just one PCB that contains all the information for all the processes?
