If there are two independent queries (i.e. no data link between them), results will also be independent. Such a principle enables you to write a report which, for example, displays an average daily temperature during last month (one query) and total amount of sold cars in Botswana (another query); there's no relation between those things.
If you, however, create a data link between two queries, then the second query result will be dependant on the first query results. For example, first query selects departments (names and locations), the second query selects employees who work in these departments - relation exists between department numbers in both queries, so we can link them together.
There's far more about data links in Report Builder's Online Help System; you just have to take some time and read about the issue.
