Scalability:
Scalability is the competence of the system to adapt to increased service load. A scalable system will respond more gracefully to increased load than a non-scalable one. First, its performance degrades additionally moderate and second; its resources take a longer time to accomplish a saturated state. A scalable system must have the potential to grow without having to resort to expensive design modifications. Secondly adding up machines to the distributed system shouldn't clog the network. Therefore scalable design should withstand high service load, contain the growth of the user community, and make possible simple integration of added resources.
Interrupts The hardware mechanism that enables a device to inform the CPU is called an interrupt. The basic interrupt mechanism works as follows. The CPU hardware has a wire kn
What are a safe state and an unsafe state? Answer: A state is safe if the system can allocate resources to every process in some order and still avoid a deadlock. A system is

Another solution then would be to keep a pool of threads. Whenever a new task arrives, the system would simply get a thread from pool and set that thread to work on the given task.
