What is Guaranteed delivery?

Guaranteed delivery, in the context of data transmission, refers to a system or protocol that ensures data is delivered to its intended recipient without loss or corruption. This is often achieved through mechanisms like acknowledgements, retransmission protocols, and error detection/correction. It is commonly used in scenarios where data integrity is critical, such as financial transactions, critical system updates, and important communications. Some examples of implementations include TCP (Transmission Control Protocol) for network communication and messaging queues with persistent storage.
