Biplane
A biplane has two (bi) sets of wings, and a monoplane has one (mono) set of wings. The two sets of wings on a biplane add lift, and also drag, allowing it to fly slower. The one set of wings on a monoplane do not add as much lift or drag, making it faster, and as a result, all the fastest planes are monoplanes, and most planes these days are monoplanes.

to fly
An aeroplane with two sets of wings is referred to as a biplane. The original aeroplanes were biplanes. Wood and cloth were the primary materials used in building early planes because they are lightweight materials. However, these materials were not strong enough to allow for a long wing that could provide the necessary lift while supporting its own weight. To counteract this two wings were built and cables run between them to make the two wings more rigid. Monoplanes, or planes with a single wing (as we commonly see today) were later designed as we designed spars that could provide the needed strength. The introduction of high quality lightweight metals and synthetic materials allowed for the development of even larger wings.
