Multihoming is like having more than one home. Just like you may have a house with your parents, and also stay at grandma's house sometimes.
In the world of technology, multihoming means that a computer or internet device is connected to more than one network. This is helpful because if one of the networks goes down or has a problem, the device can still use the other network to stay connected to the internet.
Imagine you are watching videos on YouTube and suddenly your home internet goes down. But, because you are multihomed, you switch to using data on your phone to keep watching videos.
Multihoming also helps with faster internet speeds by allowing devices to use multiple connections at the same time, boosting performance overall. It's like having extra paths to get you where you want to go, so you can still get there even if one of the paths is blocked or slow.
Overall, multihoming is all about having backup internet connections and faster internet speeds to keep us connected and online.
