Problem: You need a list of customers who have outstanding balances with your company of over $1000.
If you are on a network, what happens when you request data depends on the setup of the host computer, the server. A server is usually faster and more powerful than the computers connected to it on the network.
When you ask for customers with outstanding balances of over $1000, a computer set up as a file server will send out a copy of the whole Customers file to your computer. Your computer does the search through the file for the customers that meet the criteria of "Balance > $1000".
