Imagine you have a bunch of toys that you want to keep safe and organized. You might put them in a toy box or on a shelf.
Now, imagine that a whole bunch of people have really important things they want to keep safe and organized. These things might be secret plans or information about how to protect a country.
That's where defence information infrastructure (DII) comes in.
Just like you have a toy box or shelf to keep your toys safe, the military and government have a special system that keeps their important information safe. This is the DII.
The DII is made up of a bunch of different parts: computers, servers, cables, and software. All of these things work together to make sure that the information is kept safe and organized.
Think of it like a super big, super strong toy box that can only be opened by certain people who have a special key.
It's really important that the DII works perfectly because if important information gets lost or stolen, bad things could happen. So the people who work with the DII have to be very careful and make sure everything is working correctly.
So, in summary, the defence information infrastructure is a special system that helps military and government keep important information safe and organized. It's like a big, strong toy box that only certain people can access.
