Võrgupakke

Võrgupakke, often translated as network packet, is the fundamental unit of data transmitted over a computer network. Think of it as a small, self-contained message that carries a piece of information from one device to another. Each packet contains not only the actual data being sent but also essential control information. This control information, known as metadata, includes the source and destination addresses of the devices involved, sequence numbers to ensure data arrives in the correct order, and error-checking codes to verify data integrity.

When a large file or a long message is sent across a network, it is broken down into multiple smaller võrgupakke. These packets are then sent independently, potentially taking different routes through the network. At the receiving end, the packets are reassembled in the correct order to reconstruct the original data. This packet-switching approach is highly efficient, allowing multiple users to share network resources simultaneously without significant delays. Different network protocols, such as TCP/IP, define the specific structure and handling of these võrgupakke. Understanding võrgupakke is crucial for comprehending how data travels and how networks function.
