Packet Loss
When data tries to go from one place to another, and it gets lost like your lunch money in the cafeteria.
I hit the jump button, and nothing happened. My packet got lost like my lunch money in the trash.
The data was supposed to go from my phone to the server, but it got lost. Like my keys in the couch.
I sent the packet, and it never arrived. It was like my pet goldfish dying in the toilet.
