Point-to-Point Messaging is a communication method where messages are sent directly from one sender to one receiver. This ensures that the intended recipient receives the message without any intermediaries. It is commonly used in various applications, such as email and instant messaging, where a direct connection between two parties is established. In this system, messages are typically queued until the recipient is available to receive them. This allows for reliable communication, as messages are not lost if the receiver is temporarily offline. Overall, Point-to-Point Messaging is essential for efficient and straightforward communication in many digital platforms.
