An information society is a place where people rely on different kinds of technologies to gather and share information. Just like how mommy and daddy use their phones to look up information or talk to their friends, people in an information society use all kinds of devices, like computers and tablets, to get information about the world around them.
This information can be all kinds of things, like news about what's going on in the world or fun videos to watch. People can also use this information to do things like learn how to cook a new dish or connect with friends and family who live far away.
It's like having a big library at your fingertips that you can access anytime you want. And just like how you learn new things in school, people in an information society are always learning and discovering new things because there's so much information available to them.
