The book discusses the incorporation of interactive processing into operating systems after the original batch processing was up for improvement. In interactive processing, programs being executed can now directly communicate with the user through remote terminals. Before, the programs had to communicate with another device which then forwarded messages or instructions to the user. This allowed room for translation and problems. This is very similar to the game "Telephone" which I actually played over my fall break while backpacking in the U.P. In a group of 18 people, the person at the front of the line sent a message to the person directly behind them and the process continued until the last person in line was contacted. As was expected, the message was very different from the original. The game "Telephone" is like the old batch processing that was used before.
In order to properly communicate, it would be most beneficial for the leader to directly talk with the person in the rear, which is what occurs in interactive processing. Passing the message back took time and effort, delaying the process and manipulating the message, similar to the issues found with the old method of batch processing. While "Telephone " is a fun past-time while wondering the woods, when executing jobs on a computer, interaction is necessary to keep frustration levels down and success high.
