Digitization is the method of changing information which could be an image of text, music, movies etc into a digital format. This allows the information to become organized into separate pieces of data (bits) making it easy to access them separately.
Most importantly, since the information has turned into binary data (which allows digitization to happen), it becomes capable of being processed through other devices, as long as they have computing capacity such as a digital camera or a scanner that turns the image of text into an image file such as bitmap.
This video shows the man turning book pages into digital format.
This video shows a different side as it shows some of the problems created by digitization of music.
Along with digitization came minimization, this refers to reducing something to the smallest size possible. Such as the development of a big open reel tape recorder to small mp3 recorder to an even smaller Digital pen voice recorder.
