What unit is commonly used to measure the print quality of an inkjet printer?
Resolution, color representation, and how long the colors remain before fading.
ResolutionMost non-pro photo printers (inkjets) have a resolution of about 4800 DPI (dot per inch) rating. Don't let the numbers bother you though. Just print a high quality large photo file on good paper with the printer's quality set to best and see the result.Dye sublimation printers feature a much less 300 DPI rating, yet provide high quality photos.
Color representationSome pro printers have 11 colors (one cartridge for each color) the cheapest ones mainly have two cartridges a black one and a tricolor one.
Paper used for the print should be of great concern here. Actually, the paper will provide the white for your prints and most of the time your printer will "mix some white" to represent the colors.
Other qualities of the paper that will affect the print quality are its texture and ability to absorb the ink.
Print LifeSome Brands promote their products to yield prints that hold their colors for a century!
It is the nature of things to fade, but it is still nice to have these prints last a bit.
Again paper type is of concern here as well as exposure to light and contaminants that may reside in the air.

What does the power supply of a computer do?
- A power supply's job is to convert an Alternating Current (AC) signal coming from your wall outlet into a usable Direct Current (DC) signal. Simply stated, this process is done by stepping down the input voltage level with a transformer and then rectifying it to convert to DC. Once the DC signal is generated it is used to power all the devices and components of your system. In order to distribute the signal around to every component, many internal or external splitters can be attached to satisfy the number of connected devices. Usually a preset number of leads are provided by manufacturers to make this splitting procedure simple or even unneeded to the end user (as proper voltage values must adhere to specifications). From there, voltage regulation (often in the way of capacitors) is used to prevent your power supply from outputting too much or too little power. This protective mechanism is often called over current protection, over voltage protection, or over power protection. It is always important to ensure that your power supply has built-in regulation capabilities or spikes / sags due to fluctuations from the supply could damage your components. Alternatively, connecting your power supply to an Uninterruptible Power Supply (UPS) unit can greatly eliminate any potential harm due to external conditions on the unit.
- For computers the power supply is most responsible for providing power to the motherboard, your hard drive, CD drives, expansion cards, etc. In most cases, a single PSU unit (as opposed to a redundant power supply setup where multiple PSUs are cascaded in case one fails) is responsible for powering all parts internal to the system. Some external devices such as keyboards, mice, and external drives may also draw power either directly or indirectly from the power supply. This makes the power supply a critical component to the system. That's why when the power supply fails, your system will no longer operate.
