The Advantages and Applications of Polling Queues in Computer Systems for Asynchronous Communication

Polling Queues

The most common form of queue in computer programming. It creates a middleman,where one process sends to the queue a message, and another process then requests that message so it can perform the work specified in the message

Polling queues, also known as message queues, are used in computer systems to allow for communication and coordination between different processes or threads.

A polling queue is a mechanism for passing messages between two or more processes or threads. The process or thread that sends a message puts it onto the queue, while the process or thread that receives the message takes it off the queue. This allows for asynchronous communication between processes, where each process doesn’t have to wait for the other to finish its task before continuing.

Polling queues can be implemented in different ways, depending on the specific requirements of the system. One common approach is to use a first-in, first-out (FIFO) queue, where messages are processed in the order they are received. Another approach is to use a priority queue, where messages are processed based on their priority level.

Polling queues can be used in a variety of applications, such as job scheduling, process coordination, and inter-process communication. They are particularly useful in distributed systems, where processes may be running on different physical machines and need a way of communicating with each other.

One advantage of polling queues is that they can be used to decouple different parts of a system, allowing for greater flexibility and modularity. For example, if one part of a system needs to be upgraded or replaced, the other parts can continue working and communicating via the polling queue.

However, polling queues can also introduce overhead and complexity into a system, particularly if there are many processes or threads involved. In some cases, a different communication mechanism, such as shared memory or sockets, may be more appropriate.
