Distributed Processing Client-server computing is about spreading the information and storing loads. Most of the information was processed on one computer until about 20 years ago — the same computer on which all the processing was performed.The only reason they may have kept an extra copy of the data on another computer was for storage or backup purposes. When others need the, they would get another computer and copy the data.
