Pakettimallin

Pakettimallin is a Finnish term that translates to "packet model" in English. It refers to a concept within telecommunications and computer networking that describes how data is transmitted in discrete units called packets. Instead of sending data as a continuous stream, it is broken down into smaller, manageable chunks. Each packet contains not only a portion of the data but also essential control information, such as the sender's and receiver's addresses, packet sequencing numbers, and error-checking codes.

This packet-switching approach offers several advantages. It allows multiple users to share network resources efficiently, as different packets from various sources can be interleaved on the same communication lines. If a packet is lost or corrupted, only that specific packet needs to be retransmitted, rather than the entire data stream. This makes the network more resilient and robust. The concept of pakettimallin is fundamental to modern internet protocols, including TCP/IP, which underpins much of global digital communication. Understanding pakettimallin is key to comprehending how data moves across networks and the internet.
