ISP Information:
Photosensitive CCDs are used in scanners, digital cameras, and video cameras. The CCD basically reads the image by storing a group of charges based on the image to which it is exposed. These charges are analog charges, as opposed to simple digital on/off charges. Thus, you can grab degrees of light and color to transfer a visual image into a group of electrical charges, and then to your computer screen, video tape, or pr ISP Glossary:
CCD - In article ,kd1s@nospamplease.verizon.reallynospam.net says... [TELECOM Digest Editor's Note: Well, the workers can't have it both ways, either. Did it occur to you that much of the union excesses of the 1970-80's was partially responsible for the condition things are in today, with all the outsourcing of labor to India and such places? PAT] But how does that account for those of us who have never been part of a union, yet feel the effects of the outsourcing movement?Simple. Due to union-negotiated contracts, it's almost impossible tolayoff union members except by attrition, and then only the lowestwage categories get eliminated (the higher ones remain, as a wholechain of folks are promoted to replace the retiring worker, leavingthe lowest job in the change as the one to be attrited).Consequently, when companies with large numbers of union members lookto contain expenses through payroll reductions, they look to thenon-union, "employment at will" employees that are the first to go.If those positions still are required, then offshoring becomes aviable option.An interesting analysis for what may be happening with this and othersimilar union contract negotiations was made by columnist Rich Loweryback in January.
