Question

If a message is lost during transfer between two systems, what automated process must occur to confirm the message was received without sending duplicate data that could break the system?

Accepted Answer

To fix a lost message without sending duplicates, systems use a process called an acknowledgment with unique IDs. Each message is given a specific tag, like a serial number, so the receiver knows exactly which message it is. When the receiver gets a message, it sends back a short note called an acknowledgment, or ACK, which tells the sender that the message arrived safely. If the sender does not get an ACK back within a set amount of time, it assumes the message was lost and sends it again. Because the message has a unique ID, the receiver can check if it already has that specific tag stored in its system. If it sees the same tag twice, it simply ignores the extra copy, which prevents the system from breaking.
