Final answer:
The T-account format shows how transactions affect individual accounts with a two-column 'Assets' and 'Liabilities' layout, different from a journal.
Step-by-step explanation:
The format that provides a view of how transactions affect each account as a whole, as opposed to the journal which provides a chronological listing of accounting activity, is the T-account.
A T-account is a balance sheet tool that uses a two-column format to represent accounts, showing debits on the left and credits on the right. The T-shape is created by a vertical line down the middle and a horizontal line under the column headings for "Assets" and "Liabilities." This allows for a clear visual representation of the effects of transactions on individual accounts.
