Okay kiddo, so let's say you have a cookie and your friend also wants to have a piece of it. You can share your cookie with your friend by breaking it into two pieces and giving one to your friend, right?
Just like that, in computer terms, disk sharing means allowing other people or computers to access the information and files saved on your computer's hard drive. It's like sharing your cookie, but instead of a cookie, it's information on a computer.
For example, you may have some family photos saved on your computer and you want to show them to your grandparents who live far away. You can share the folder where you have saved the photos and give them access to it so they can see the photos from their own computer without you having to email them or physically transfer them.
Disk sharing can be done using different methods, such as setting up a shared network folder or using cloud storage services like Dropbox or Google Drive. But just like you wouldn't want to share your cookie with just anyone, you should also be careful about who you share your computer's files with and make sure you set up proper security measures to protect your information.
