data packets

**data packets**
Data packets are small units of data transmitted over a network. When information is sent from one device to another, it is broken down into manageable pieces called packets. Each packet contains not only a portion of the actual data but also metadata such as destination and source addresses, error-checking information, and sequencing details to ensure the data is reassembled correctly at the receiving end. Understanding data packets is fundamental to networking, internet communication, and how digital information travels efficiently across various systems.
