What is Thread starvation? How can a synchronized block cause Thread starvation in Java?

What is Thread starvation?

In a priority based scheduling, Threads with lower priority get lesser time for execution than higher priority threads.

If a lower priority thread performs a long running computation, it may happen that this thread does not get enough time to finish its computations just in time.

In such a scenario, the tread with lower priority would starve. It will remain away from the threads with higher priority

How can a synchronized block cause Thread starvation in Java?

It is not defined for synchronization that which thread will enter a synchronized block.

It may happen that if many threads are waiting for the entry to a synchronized block, some threads may have to wait longer than other threads.

Hence these threads with lower priority will not get enough time to finish their work in time

How does cloud computing work, and what are the benefits and drawbacks of using it?

Cloud computing is a model for delivering information technology services over the internet. Instead of having software and hardware installed locally on a user's device, cloud computing allows users to access applications and data through a network of remote servers, usually maintained by a third-party provider . This provider is responsible for managing and maintaining the infrastructure, including servers, storage, databases, and software . Here is a more detailed explanation of how cloud computing works: Remote servers: Cloud computing relies on a network of remote servers that are maintained and managed by a third-party provider . These servers can be physically located anywhere in the world. Internet connectivity: To access cloud computing services, users must have an internet connection. This connection allows them to remotely access the resources on the remote servers. Virtualization: Cloud providers use virtualization technology to create multiple virtual machines ...
