👉 Messaging in computing, often referred to as "mess" or "computational messaging," is a fundamental concept in distributed systems and networking where data is transmitted between different components, processes, or even machines over a network. This process involves encoding information into packets, which are then sent across the network, potentially traversing multiple intermediate nodes. Each packet may include headers containing addressing information to ensure it reaches the correct destination, and sometimes additional data for reassembly or error checking. Messaging systems facilitate communication by abstracting the complexities of network protocols and hardware, allowing applications to interact in a standardized and efficient manner. This abstraction is crucial for building scalable, reliable, and flexible systems, enabling services like email, web browsing, and real-time data streaming to function seamlessly across diverse and distributed environments.
