Imagine you have a big toy room filled with all kinds of toys that you love to play with. Now, imagine you invited all your friends to come play in your toy room, but some of them don't have any toys of their own to bring. So, you decide to share your toys with them, but you also make sure that everyone plays nice and takes turns playing with the toys.
In a similar way, an open-access network is like a big toy room filled with all kinds of internet connections and services that people can use. The network is owned by a company or government, but it's open for anyone to access, just like anyone can come and play with toys in the toy room.
This is important because it means that people who might not have internet access at home can still get online and use services like email, social media, and video calls. It also means that people who want to start their own businesses or create new online services can do so without having to pay a lot of money to access the infrastructure they need.
Just like in the toy room, the people who use the open-access network have to follow some rules to make sure everyone can use it fairly. For example, they may need to pay a fee to access the network or agree to certain terms of use. But overall, the goal of an open-access network is to make the internet more available and affordable for everyone, just like how sharing your toys can make playtime more fun for everyone.
