Answer:
An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process. It may be an improvement upon a machine or product or a new process for creating an object or a result.
Development is always deliberated with economic connotations and it is referred to as an increase in the gross national product or in per capita income. In this understanding, development is equated with growth and it is envisioned that a quantum increase in the production of goods and services would bring development.
Papyrus is a material similar to thick paper that was used in ancient times as a writing surface. It was made from the pith of the papyrus plant, Cyperus papyrus, a wetland sedge.
However, Cai's most noted product was in 105, when he substantially improved the papermaking process with the use of tree bark, hemp waste, old rags, and fishnets.
One of the main benefits of the printing press was that it allowed ideas and news to be shared quickly which helped usher in the Renaissance, Reformation, the Age of Enlightenment and the scientific revolution.
