👉 Packet computing is a method of data transmission that breaks down large data streams into smaller, manageable packets for efficient transfer over networks. Each packet contains a portion of the original data along with essential information like source and destination addresses, sequence numbers, and error-checking codes. As packets travel through the network, routers direct them based on these headers, ensuring they reach their intended destinations. Upon arrival, the packets are reassembled at the receiving end, reconstructing the original data. This approach enhances network efficiency and scalability, allowing multiple data streams to share the same communication channel without interference, and is fundamental to modern internet and network communications.
