Q. What resources are utilized when a thread is created? How do they vary from those used when a process is created?
Answer: For the reason that a thread is smaller than a process thread creation typically uses fewer resources than process creation. Creating a process necessitate allocating a process control block (PCB) a rather large data structure.
The PCB comprises a memory map list of open files and environment variables. Allocating as well as managing the memory map is usually the most time-consuming activity. Creating either a user or else kernel thread involves allocating a small data structure to hold a stack, register set and priority.
