How database records reside in memory?

A physical database file (.mdf) is logically divided in to data pages. A data page can go up to 8 KB. SQL Server stores records(rows) in a data page. One row cannot splitt across two data page and because of that a row can grow up to 8 KB only. If an index is added in to the table and ASC or DESC is specified, records are sorted according that order.
