Packet data refers to the method of transmitting digital information over networks by breaking it into smaller units called packets. Each packet contains a portion of the data, along with headers that include source and destination addresses, sequencing, and error-checking information. This approach is fundamental to how the internet and mobile data networks operate, enabling efficient, flexible, and reliable communication. Packet-switched networks allow multiple data streams to share the same transmission path, improving bandwidth usage and reducing congestion. It is commonly used in mobile communications for services like web browsing, email, and streaming.
