Message queuing theory

Message queuing theory analyzes how messages are temporarily stored and managed as they travel between systems, like data or instructions. Imagine a line of people waiting to buy tickets; each person is served in turn, ensuring order and efficiency. Similarly, message queues hold data until the receiving system is ready to process it, preventing overload and delays. This theory helps optimize communication between computers and applications, ensuring smooth, reliable data transfer even during high traffic or network issues. It’s essential for building scalable, responsive systems in today's digital infrastructure.
