pixel -_- functional definition

pixel

(PIX [picture] ELement) Generally, the smallest addressable unit on a display screen or bitmapped image. Screens are rated by their number of horizontal and vertical pixels; for example, 1024x768 means 1024 pixels are displayed in each row, and there are 768 rows (lines). Likewise, bitmapped images are sized in pixels: a 350x250 image has 350 pixels across and 250 down.

     With color systems, each pixel contains red, green and blue subpixels, and the subpixel is actually the smallest addressable unit. The monitor's circuits address subpixels, and the software may also. When referring to hardware at the lowest level, the term "pixel" often really refers to "subpixel." See dead pixel.

Pixel Structures
In storage, pixels are made up of one or more bits. The greater this "bit depth," the more shades or colors can be represented. The most economical system is monochrome, which uses one bit per pixel (on/off). Gray scale and color typically use 4 to 24 bits per pixel, providing 16 to 16 million colors. See bit depth.

Displaying the Pixel
On a display screen, pixels are either phosphor or liquid crystal elements. For monochrome, the element is either energized fully or not. For gray scale, the pixel is energized with different intensities, creating a range from light to dark. For color displays, the red, green and blue subpixels are each energized to a particular intensity, and the combination of the three color intensities creates the perceived color to the eye. See resolution and vertex shader.


A Monochrome Bitmap The simplest pixel representation is a black and white monochrome image in which one bit represents one pixel. Monochrome CRTs use white, green or amber phosphors as a single color over a gray/black screen background.



Pixel Resolutions These are the primary resolutions displayed on a PC. With more pixels on screen, more of the document is visible, but the text and images will appear smaller.

What if…OS zealots ran major airlines?

What if…OS zealots ran major airlines?
Found on Zyra.org:
"Different operating systems. Different styles. But what if the quirks and styles of the different operating systems were applied to AIRLINES? What if airlines ran things the way operating systems do? This humorous analogy, applying operating system philosophies as if they were airlines, is a long-standing much-circulated amusing story…". For example:
· Mac Airlines:"All the stewards, captains, baggage handlers, and ticket agents look and act exactly the same. Every time you ask questions about details, you are gently but firmly told that you don't need to know, don't want to know, and everything will be done for you without your ever having to know, so just shut up."
· Air DOS:"Everybody pushes the airplane until it glides, then they jump on and let the plane coast until it hits the ground again. Then they push again, jump on again, and so on…"
· Windows Air:"The terminal is pretty and colourful, with friendly stewards, easy baggage check and boarding, and a smooth take-off. After about 10 minutes in the air, the plane explodes with no warning whatsoever."
· Linux Air:"Disgruntled employees of all the other OS airlines decide to start their own airline. They build the planes, ticket counters, and pave the runways themselves. They charge a small fee to cover the cost of printing the ticket, but you can also download and print the ticket yourself. When you board the plane, you are given a seat, four bolts, a wrench and a copy of the seat-HOWTO.html. Once settled, the fully adjustable seat is very comfortable, the plane leaves and arrives on time without a single problem, the in-flight meal is wonderful. You try to tell customers of the other airlines about the great trip, but all they can say is, 'You had to do what with the seat?'"
And that's only half the list. Got any you want to add?
Different operating systems. Different styles. But what if the quirks and styles of the different operating systems were applied to AIRLINES? What if airlines ran things the way operating systems do? This humorous analogy, applying operating system philosophies as if they were airlines, is a long-standing much-circulated amusing story, and we'd credit the author if we knew who wrote it!
If Operating Systems Ran The Airlines...
UNIX Airways: Everyone brings one piece of the plane along when they come to the airport. They all go out on the runway and put the plane together piece by piece, arguing non-stop about what kind of plane they are supposed to be building.
Air DOS: Everybody pushes the airplane until it glides, then they jump on and let the plane coast until it hits the ground again. Then they push again, jump on again, and so on...
Mac Airlines: All the stewards, captains, baggage handlers, and ticket agents look and act exactly the same. Every time you ask questions about details, you are gently but firmly told that you don't need to know, don't want to know, and everything will be done for you without your ever having to know, so just shut up.
Windows Air: The terminal is pretty and colourful, with friendly stewards, easy baggage check and boarding, and a smooth take-off. After about 10 minutes in the air, the plane explodes with no warning whatsoever.
Windows NT: Air Just like Windows Air, but costs more, uses much bigger planes, and takes out all the other aircraft within a 40-mile radius when it explodes.Windows XP Air You turn up at the airport, which is under contract to only allow XP Air planes. All the aircraft are identical, brightly coloured and three times as big as they need to be. The signs are huge and all point the same way. Whichever way you go, someone pops up dressed in a cloak and pointed hat insisting you follow him. Your luggage and clothes are taken off you and replaced with an XP Air suit and suitcase identical to everyone around you as this is included in the exorbitant ticket cost. The aircraft will not take off until you have signed a contract. The in-flight entertainment promised turns out to be the same Mickey Mouse cartoon repeated over and over again. You have to phone your travel agent before you can have a meal or drink. You are searched regularly throughout the flight. If you go to the toilet twice or more you get charged for a new ticket. No matter what destination you booked you will always end up crash landing at Whistler in Canada.
Linux Air: Disgruntled employees of all the other OS airlines decide to start their own airline. They build the planes, ticket counters, and pave the runways themselves. They charge a small fee to cover the cost of printing the ticket, but you can also download and print the ticket yourself.When you board the plane, you are given a seat, four bolts, a wrench and a copy of the seat-HOWTO.html.
