What term refers to divided parts of data being transmitted on a network?

The term that describes divided parts of data being transmitted on a network is "Data Packets." When data is sent across a network, it is broken down into smaller, manageable pieces known as packets. This process is crucial for efficient data transmission since it allows for error checking, reordering, and the ability to send data across different routes in the network. Each packet may take a different path to the destination, where they are then reassembled into the original data.

Using packets also enhances network performance and reliability, as they can be retransmitted if lost, ensuring that the data reaches its final destination intact. This method of data transmission is foundational to how networks, especially the internet, operate today.
