How does the system use and allocate resources when creating a new thread of execution?

When creating a new thread, the operating system allocates a separate memory stack and data structures for managing the thread's state. Resources are distributed as follows:

• Thread stack: a fixed-size memory area for local variables and function calls.
• Execution context: a structure containing CPU registers, instruction pointer, and other data needed for thread switching.
• Thread ID: a unique ID assigned by the system for management.

When the thread starts, it receives CPU time from the OS scheduler, which allocates resources among all active threads. Creating a thread involves costs for memory allocation and initialization, so in Android, thread pools (ThreadPool) are often used for resource reuse and performance enhancement.
