A network file system (NFS) protocol is like a magic language that allows computers to share files with each other even if they are far away from each other. It's like having a big toy box with a lot of toys, but it's not at your house, it's at your best friend's house. And you can't go to your friend's house, so you can use the NFS protocol to get access to the toy box from your own house, like magic!
Now, let's get a little more technical. NFS is a protocol that runs on your computer's operating system and allows you to share files and directories (folders) from one computer with another. When you want to access a file or folder, your computer sends a message in the NFS language to the other computer asking for permission to access it. If the other computer grants permission, it sends the file or folder back to your computer so you can use it.
NFS is a very useful protocol because it allows multiple computers to access the same files and folders at the same time, even if they are in different locations. It's like having a virtual file cabinet that all your friends and family members can access, regardless of where they are in the world.
In summary, NFS is a special language that lets your computer talk to other computers far away and share files and folders like they're right next to you. It's like magic!
