Packets
In networking, a packet is a small segment of a larger message. Each packet contains both data and information about that data.

The internet is like a giant delivery system for information, and that information is sent in the form of packets. Each packet gets passed from one device to another until it reaches its final destination.
When you send a message or request something online, your device breaks that information down into small packets. Each packet is like a little traveler, with its own set of instructions on where it needs to go and what it needs to do.
As these packets make their way across the internet, they travel through a series of switches and routers, each one directing them closer to their destination.
Eventually, the packets reach their final destination, where they're reassembled into the original message or request.
All data sent over the Internet is broken down into smaller chunks called "packets."
A packet has two parts: the header, which contains information about the packet itself, and the body, which is the actual data being sent.
When one Hitchhiker sends another Hitchhiker a message, for instance, her message is broken down into smaller pieces and then reassembled on the computer.
Frames are "Layer 2" data sent between the computers which include the Mac Addresses of the devices across the network and upgrades become packets when they have "Layer 3" information like IP address attached to it.
In networking, a packet is a small segment of a larger message. Each packet contains both data and information about that data.
The packets get routed to their destination by various networking devices such as routers and switches.
When the packets arrive at their destination, the receiving device reassembles the packets in order and can then use or display the data.
Packet encapsulation allows for data to be correctly addressed and moved through all the layers of the Internet protocol without any issues. Think of it like a galactic delivery man in charge of logistics.
