Structure of Social Security Numbers. A Social Security Number (SSN) consists of nine digits, commonly written as three fields separated by hyphens: AAA-GG-SSSS.

Fabrication, is the building of something brand new, that's never been seen before, or invented. Manufacturing, is the duplication of something on a mass scale. Generally, the way it works is, you fabricate something that you need, then manufacture what you fabricate. A good example is, a car company decides to design a brand new car from the ground up.
This makes process manufacturers âprocessâ or formula based. Discrete manufacturers are making a finished good that may have screws, nuts, handles, etc. that can be taken apart and used on something else if need be. In discrete manufacturing the manufacturing floor works off shop orders to build something. The individual products are easily identifiable. While in process manufacturing, you canât tell the difference between one product and another. The biggest difference between these two distinct manufacturing areas is that outcome of discreet manufacturing can be without difficulty reversed, while with process manufacturing there is no way to do it.
