When a thread is ready to resume execution after losing access to the CPU (due to reasons like time-out, sleep, block, or wait state), it is typically placed at the rear of the ready-queue. This ensures that it waits its turn based on the scheduling policy being used, which often aims to provide fair access to the CPU among all ready threads.
