Okay kiddo, you know how when you look at a clock, you can tell what time it is? Well, when computers talk to each other, they have their own kind of clocks that help them keep track of time.
But sometimes, these clocks can get mixed up and start telling the wrong time. So to make sure everyone is on the same page, each computer gets its own special identity in the form of a clock ident number.
This number helps other computers know which clock they're talking to, and makes sure that everyone is using the same time so that things like sending emails or making sure your favorite game works properly can happen smoothly.
So, think of clock ident like a name tag for a computer's clock - it helps everyone stay organized and know who they're talking to. Hope that helps!
