Earliest period

Journey

The term originally referred to a functional item on a writing desk—a box containing fine sand or pounce used to sprinkle over wet ink to absorb excess moisture before blotting. By the late 19th century, it became associated with recreational play areas for children, and in the late 20th century, the term was adopted by the computing industry to describe a secure, confined space for software execution.
