What methods are used to prevent data loss during information transfer to the server?

The following methods are used to prevent data loss during transmission to the server:

• Using protocols with delivery acknowledgment (e.g., TCP).
• Encrypting data to protect against distortion and interception.
• Data integrity control using hash sums or CRC.
• Resending data upon error detection (retransmission mechanisms).
• Using transactions and atomic operations on the server.
• Logging and monitoring transmission to detect failures.

For example, when uploading a file, the client can split it into parts and confirm the receipt of each part by the server.
