- Information is piecemeal, fragmented, particular;is timely, transitory, perhaps even ephemeral, is flow of messages
- Data, e.g., trade and industrial statistics, price index, entertainment announcements, etc.
- Information, e.g., processed information of weather to warn farmers during times of monsoons, stock exchange information for investments, reports of music concerts, news about national and international events,etc.
- Knowledge, e.g., press responsibilities vis-à-vis democratic institutions in the form of a report, international information order as exemplified by the third world countries meetings, the books such as ‘Many Voices One World’ published by UNESCO, etc.
- Brookes fundamental equation of information science is K [S] +D I = K [S+ D S]
