Step-by-step explanation:
An example of a less tangible component of a country's infrastructure is knowledge and information systems. While physical infrastructure like roads and bridges are tangible and can be seen and touched, knowledge and information systems are intangible but essential for the operation of a society. These include educational institutions, libraries, internet connectivity, and digital databases.
Knowledge and information systems play a crucial role in promoting innovation and invention, as they provide people with access to information, research, and ideas. For example, a country with well-developed educational institutions and a high-speed internet infrastructure has a stronger knowledge and information system, which can contribute to its economic growth and technological advancement.
