Information System Diagram Employing a Buffer
With all of the talk about "buffers" and "buffer stocks" lately, I thought it might be helpful to sketch a quick rudimentary diagram of a basic information processing system that is a system that typically employs buffers in order to preserve critical external input/output information items.
This may help people to visualize a system that typically uses a buffer sub-system.
I think there perhaps is some cross over in the structure of a critical information processing system and a properly designed macro economic system under a Free Floating Non-Convertable currency.
1. The buffer is not included to "smooth things out", it is included to PRESERVE externally sourced input/output information that has ALREADY BEEN DETERMINED to be of high and critical value.
2. The buffer is employed when independent external inputs overwhelm the C-interface from I/O control to the central process. The data is moved through the B-interface up into the buffer and is usually retrieved from the buffer on a first in/first out basis when the the central process "catches up" with the rate of external information flow through the A-interface which can swamp the central processor.
3. The "invisible hand" acts as the I/O Controller in our economy, and it is not clear to me that anyone has in fact included an I/O buffer sub-system in our economy.
4. No a priori value is placed on the external inputs to our economic system by any system design authority.
5. Lack of inclusion of a properly designed buffer sub-system will result typically in a complete system failure, or even worse errors that can result in deaths in a critical safety-of-life system, if the independent external information flows overwhelm the input/output capability of the central process.
I have the diagram open as a Google Doc here for access.
