Which of the following best explains how data is typically assembled in packets for transmission over the internet?
Answer:
Data is typically assembled in packets for transmission over the internet using a process known as packetizing. Here is an explanation of how data is assembled in packets:
1. Packetization: When data is transmitted over the internet, it is broken down into smaller units called packets. Each packet contains a part of the data being sent, along with additional information such as the source and destination addresses.
2. Header Information: Each packet includes header information that specifies where the packet came from, where it is going, and how it fits into the sequence of packets being sent. This header information helps routers on the internet route the packets to their destination.
3. Transmission: Once data is divided into packets and each packet is assigned header information, these packets are transmitted individually over the internet. The packets may take different paths to reach the destination and may arrive out of order.
4. Reassembly: Upon reaching the destination, the packets are reassembled into the original data by the receiving device. The header information is used to rearrange the packets in the correct order, allowing the data to be reconstructed accurately.
In summary, packetizing involves breaking down data into packets, adding header information for routing, transmitting the packets individually, and then reassembling them at the destination to retrieve the original data.
