Five Band Resistor Color Code-What Does The Last Band Of White Color Represent?
If you open up an analog multimeter you will understand what i mean. Most of the resistor circuit insidethe multimeter are using five color band. Why? Because the reading that you get whenever you measure current,voltage or ohm, the panel will show the nearest value. For instance, if you measure a 9v batterythe needle will point to may be 8.9v,9v,or 9.1 volt. If that particular multimeter was designedusing four color band resistor the result that it gets may be 8.5v,9.5v or even 10 volt. In otherwords the use of five color band resistor is to make a circuit more precise and output the desireresult as what the engineers want it to be.
There's a interesting five color band resistor which is unique.In fact i have already seen quite a number of them. I will reveal the calculation about thisunique five color band resistor. The colors are orange, orange, red, gold, white.Actually it is a four color band resistor. Just ignore the white color and proceed to calculateusing the four color band formula. As to why the resistor manufacturers add this 'extra' whiteband i really do not know. However, from forum someone said that it is for the military purposes. If you know the answer i would like you to email me so that i can share with other fellow electronic repairer thru this info repairing newsletter.

At this point, most people panic. The first thing you wonder is whether or not the data is recoverable. There is no universal answer to this. In some cases, a simple scan with some data recovery software is all that it takes to retrieve the contents of the drive. In other cases, if you want it badly enough, it will take thousands of dollars and a shipment of the drive to a clean lab where they will pull the platters inside of the drive and access them that way.
Where does technology come from?
But now we are seeing things move so fast that the general population will be getting the new technologies in some way or another within a few years from discovery and proving of concept. Many things are now being created in private sector and the military is finding great applications for them such as the palm computer technology for Navy Seal Teams, cell phone telemetry tracking. What about the private sector protecting their rights to these advances? Patents? Who cares, by the time you get the thing filed everyone has it, four of your former employees brought it to your competitors, your key vendors sold it or partnered with another company to make it. By this time it is already on the shelves for you and I. The company with the marketing channels and fastest rollout gets the cake, but does not have time to eat it. Remember in the new age the fast eat the slow. The game never stops and people and companies enter and exit the field of their choice at will. With the Internet as a distribution channel a new wiget can be to market in months and delivered in 8-12 hours by Fed Ex if the company has their manufacturing at or near a regional hub. The World is changing and we maybe getting many of these new technologies a lot faster than before. Think about it.
Why You Shouldn't Try Data Recovery Yourself
In the world of computers, data recovery is something we all know and rely on to recover lost of missing data. The process of data recovery is very complicated, one that you should never attempt to do yourself. Hard drives especially, are very fragile and need extra special care when they are worked on. You have to be careful with the small components inside of them, which is why only a trained specialist should be attempting data recovery.
