  • 2.5 quintillion bytes of data are produced by humans every day in 2021 and is expected too rise
  • Before data can be sent across the internet, the TCP is used to break it into fixed-size chunks. These are known as datagrams, but are sometimes called packets.
  • A packet consists of control information and user data; the latter is also known as the payload. Control information provides data for delivering the payload (e.g., source and destination network addresses, error detection codes, or sequencing information).
  • packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, or network congestion.
  • in the Internet architecture the network layer is responsible for routing packets through the packet-switched network from the source to the destination. The transport layer is responsible for end-to-end communication, from an application running on the sending host to its peer running on the destination host.
  • if the router is busy or broken packet loss is occurring / has occurred
