Don't Memorize

Printing Media Sizes Printing media comes is standard sizes. The size is chosen primarily because of the sizes accepted by the printing machines, both in digital and offset. It is very important to understand the size of the media available because that will help us calculate the number of products we can ‘fit’ on a single sheet. When designing or creating a print product, the first thing one has to define and specify is the final size of the product. Then one has to calculate the number of such products that can be created from a standard size of paper available for the printer. For example, if the product is an A6 postcard, the total number of cards that can fit in an A3 sheet is 8. To understand this, first, let us understand the types of sizes. Standard Paper Sizes: Size Name width x height (in mm) width x height (in inches) Comments A0 841 × 1189 33.11 × 46.81 A1 594 × 841 23.39 × 33.11 Use for wide format media and CAD / CAM drawings A2 420 × 594 16.54 × 23.39 A

GSM in Paper GSM  is an acronym standing for ' Grams per Square Meter '.  Quite simply, it allows print buyers and print suppliers to know exactly about the quality of  paper that is being ordered.  The higher the  GSM  number, the heavier the  paper . The height of 100 sheets with different GSM looks like below

Chassis Intrusion connector A connector found on a  motherboard  that supports a  chassis security feature that detects if a chassis component is removed or replaced, in which case an alarm sound is heard through the onboard speaker or PC chassis speaker if present. For the chassis intrusion circuit to work, the chassis power supply must be connected to AC power. By default, on the motherboard, the pin labeled chassis "signal" and "ground" are shorted with a jumper cap. You need to remove the jumper caps if you intend to use the chassis intrusion detection  hardware .
