The primary factor that determines uptime for servers in a colocation facility is power. Power outages will knock a network offline and even damage hardware such as motherboards, memory, and hard drives. Despite how intrinsic power is to keeping businesses connected to their networks, only 2% to 3% of colocation facilities have the right power systems in place. The other 97% of facilities most commonly lack redundancy, multiple units carry the energy load even if one unit fails, or have units that are running above capacity, so a unit failure will cause the other units to overload and fail. Every part of the power system uninterruptible power supplies (UPS), transfer switches or circuit breakers, generators, and power distribution units (PDU) should be redundant and running below capacity.
Problem 1: Non-redundant Power Grids
Multiple PDUs connected to separate power grids and multiple UPSs should be designed into the colocation facility to offset a power grid failure. Colocation facilities with redundant power grids can connect customer servers to different grids at the same time, so that even if one goes offline, the other will work, keeping the network running without interruption.
Problem 2: Non-redundant UPSs
The UPSs supply power during an outage until the generator can come online; if the UPSs do not turn on immediately at the time of failure, then the network will go down. Even with high quality UPSs, failures are common, so it is critical for there to be multiple redundant UPS units in an n+1 configuration all of the necessary UPSs, plus an extra. Functionally, this means that each UPS runs sufficiently below capacity to handle a unit failure without the other units overloading. If there are two UPSs, then each unit must run below 50%, so that if one fails, the other can continue without overloading. If there are three units, each must run below 66%; four units, below 75%. The current load is shown on the display on the front of the UPS.

If there is anything I have learned in the past ten years of being an editor that is using my computer all day, it is that it is good and right to be absolutely picky when it comes to choosing computer keyboards. If this seems like an insignificant choice to you, then it is clear that you, unlike me, do not spend the majority of your days typing on a computer.
If you did, you would quickly realize what a difference computer keyboards can make to a typing experience. It took me a couple of years to realize that there were actuallly a lot of options when it comes to computer keyboards and that I didn’t have to be satisfied with a computer keyboard that didn’t fit my hands.
I have probably made my way through at least eight or nine computer keyboards in the past ten years. I have learned what suites my body and my needs better and that has often caused me to go on the hunt for a newer and better computer keyboard. I have learned that there are a huge variety ofAs computer keyboards and that if you search for them, they do not have to be too expensive or hard to find.

In the world of home ink jet color printing, there is some confusion concerning CMYK color and RGB color. Many photo enthusiasts don’t realize what kind of color space their digital cameras output and are confused when it comes to printing images off of their home ink jet printers. They hit print and wonder why the printed image looks different from what they see on their monitor.
CMYK is the color description representing printed material, short for the colors Cyan, Magenta, Yellow, and Black. Mixing these 4 colors together in different amounts give you the millions of colors that reproduce the colors in printed material. These are actual inks used in printing the images you see in color magazines and books. RGB is the color description for images viewed on your computer monitors, short for Red, Green, and Blue. RGB color is actually light, and mixing different levels of these light colors
creates the millions of colors that come from your computer monitor. All websites and nearly everything you see on your computer monitor is RGB unless the images have been converted to the CMYK color space.
When you print your images on your ink jet printer from your computer, your printer prints the image using CMYK inks. Viewing your image in RGB and then printing it out in CMYK may not yield the results you want. Programs such as Adobe Photoshop will convert your image from RGB to CMYK or vice versa. Some printers require the image to be CMYK before you can print the image correctly. Some printers don’t print the image correctly if the image being printed is in RGB space.
A good reason for printing with a CMYK image is to see your image in CMYK color before printing. When an image is converted to CMYK from RGB, there may be some color changes that are noticeable in the image. The reason for this is because many colors in RGB cannot be reproduced using CMYK inks. That is why it is always a good idea to convert your image to a CMYK color space before printing. You could notice significant color changes to your image, especially in the very intense color areas of your image. Some of these intense color areas may appear less intense or very dull once converted. With photo editing software, you can go in and fix these trouble color areas to your liking.
Many ink jet printers on the market today actually print directly from an RGB color image. And converting the image to CMYK may cause it to print incorrectly. You will need to determine what color space your ink jet printer supports. The packaged software usually will give you a hint regarding color spaces. If there is no option to convert the color space from RGB to CMYK, most likely, the printer will print directly from an RGB color source. Usually, the higher end ink jet printers deal with the CMYK color space as consumer level enthusiasts don’t even know these color spaces exist. New higher end ink jet printers, however, are now printing directly from the RGB color space as there is a wider spectrum of color that can be reproduced in RGB compared to CMYK color.
