What is delta-based version control in VCS?

Question

git

Good afternoon, I'm reading a book about Git and came across this moment:

The major difference between Git and any other VCS (Subversion and friends included) is the way Git thinks about its data. Conceptually, most other systems store information as a list of file-based changes. These other systems (CVS, Subversion, Perforce, Bazaar, and so on) think of the information they store as a set of files and the changes made to each file over time (this is commonly described as delta-based version control

) please, on an example or on a diagram what is delta-based version control

Answer 1

This is a set of incremental changes for each file. An increment is the difference (delta) in changes in a file between the previous and current versions. For text files, these are changes in lines, and for binary files, in sequences of bytes.
