What parameter is commonly used to specify the beginning index for pagination in records?

• A. Limit
• B. Offset
• C. Page Number
• D. Record Count

Answer: (B)

The parameter used to specify the beginning index for pagination in records is offset. In pagination, when dealing with database queries or API responses, offset helps to determine where the collection of data should start. It indicates how many records should be skipped before starting to return the data for the current page. For instance, if you want to display results in sets of ten and you are on the second page, the offset would be set to ten, effectively skipping the first ten records and returning records 11 through 20. This allows systems to efficiently retrieve and manage large datasets, providing a user-friendly experience as only a subset of data is processed and displayed at any given time. The other options serve different roles: "Limit" specifies how many records should be returned, "Page Number" denotes which page of records to fetch without specifying the starting point explicitly, and "Record Count" refers to the total number of records available, which doesn’t indicate the starting index for a particular subset.
