The article, 'being digital' written by Nicholas Negroponte is about the pros and cons of bits and atoms.

Bit based information is stored electronically. Atom based information is stored physically in the form of a book, paper or report.

Atoms can take a long while to arrive if they are getting delivered and other problems can occur ie. things getting held up in customs. An atom based thing such as a book is easier to read when you physically have it, but there are other factors involved such as costs and delivery times., etc.

Bits are able to move through 'cyberspace' at the speed of light. Not all atom based items are able to sent as bits, these would include chinese food and other impossible to send physical items. A bit based book is able to be read easily online and will never go out of print, as it is readily available online. This is not entirely possible in the current situation, but in the future, this oppurtunity will become available to many people.

Bits and atoms can be easily confused, like the publisher of a book is 'bit based' or 'atom based?' The answer to this would be both, but as time progresses, the quality of a printed book will become outdated and it will become user-friendly to be bit based.
