For starters, let's define them. Patio is a Spanish word, which means a courtyard of a house or building. A courtyard is traditionally an open space surrounded by walls or buildings, or is an area of ground adjacent to a building. A patio differs from a courtyard in that it doesn't have to be surrounded by walls. It's similar to a courtyard in that it's an open space that can be situated directly on the ground.
Patios can be attached to a house, or detached. They are often designed and oriented with the landscape in mind. Patios are versatile: they can take on any shape and be built with a variety of materials, including concrete, pavers, stone, tile, brick, pebbles, rock or pea gravel. Most patios are set on a concrete slab or a sand and pebble base. Since patios are built at or around ground level, they don't require safety railings.
