Is a computer small enough to fit in one hand?
Mostly any handheld device is a computer. Your iPhone, calculator, etc. It depends on what you what the computer to do. A calculator will obviously calculate numbers and equations for you (perhaps in graph them).
An Iphone (or any other internet abled phone) while allow you to search the web and look up maps, etc.
GPS is a computer as well. (Global Positioning System) GPS uses satillite to position where you are at.
There are many computers that do certain things that help us move along through life more easily.
How do you calculate inventory turnover?
This is a very simple calculation. Days to Sell Inventory(or Days in Inventory) = Average Inventory / Annual Cost of Goods Sold /365 Average Inventory = (Beginning Inventory + Ending Inventory) / 2 To calculate this ratio for a quarter instead of a year use the following variation: Days to Sell Inventory (or Days in Inventory) = Average Inventory / "Quarterly" Cost of Goods Sold /"90" Average Inventory = (Beginning Inventory + Ending Inventory) / 2
What is the best age for a kid to get a cell phone?
You should get a cellphone when you think your child is mature enough and responsible enough for one. If you give your child a cellphone when their not ready they might do things with it like show it off at school or they might drop it multiple times and it will most likely be an accident when they drop it. That will show you how responsible they are. You should also get it if they are going to be going out alot(like school) but it depends if their responsible, give it to them. If they are not responsible and they go out alot well don't give it to them.
Lit up 30 years ago the laser diode is the basis of all of the world's cheap lasers.
A ruby laser (depicted earlier) is a solid-state laser and emits at a wavelength of 694 nm. Other lasing mediums can be selected based on the desired emission wavelength (see table below), power needed, and pulse duration. Some lasers are very powerful, such as the CO2 laser, which can cut through steel. The reason that the CO2 laser is so dangerous is because it emits laser light in the infrared and microwave region of the spectrum. Infrared radiation is heat, and this laser basically melts through whatever it is focused upon. Other lasers, such as diode lasers, are very weak and are used in today's pocket laser pointers. These lasers typically emit a red beam of light that has a wavelength between 630 nm and 680 nm. Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them.
Why are the notebooks usually more expensive than PCs with comparable power and features?
Because the engineering and design is more critical due to using much smaller parts. Miniaturization of the hard drives is more expensive and the heat sinking of heat producing items on the motherboard is more critical. There are a number of reason, but those are some of the most important ones.
How do you fix a wet electronic device?
There are several ways to try and dry a wet device, like an iPod or cellphone. They work to differing degrees in different times, and can be used together or alone.
- Place it in a warm, dry room for a few days, testing daily to see whether it has dried yet.
- Turn a hair dryer to low and wave it over the device from about a foot away for 20 to 30 minutes. Test it, and continue drying for another 20 to 30 minutes if necessary.
- Place it in a cup of rice (rice absorbs water, but won't clog up the device).
Using a hair dryer is a very bad idea: all it does is push the water further into the cracks and crevices of the device, making the problem worse. Rice also does not work, as it does not absorb moisture from the air, and it only absorbs a significant amount of water if the water is boiling. The only reason people say it works is that sometimes, if the device wasn't too wet to begin with, it just dries out by itself. It would have dried out without the bag of rice, but since it was in the bag of rice, people think it was the rice that dried it. Not so. The device just dried by itself.
By far the best way to dry out wet electronic devices is with silica packets. You know those little packets you find inside your new shoes, or in your medication bottle? They usually say "Silica - Do Not Eat?" These packets draw in and absorb moisture. They are put in shoes and medication bottles to keep humidity and moisture from ruining the product. Sometimes in medication bottles they come not in packets, but in little white plastic cylinders.
Every time you find a silica packet or plastic cylinder, save it. Put all of them in a sealed plastic bag, so they stay fresh and do not absorb moisture from the air. Next time one of your electronic devices gets wet, wrap it in a paper towel and seal it up in the bag with the silica packets. Wait 3 to 5 days. Your device should be good as new.
Several months ago I dropped my TV remote into a bucket of water. I didn't even notice at first, so the remote stayed submerged for nearly 10 minutes. After shaking the excess water out of it, I wrapped it in a paper towel and put it into a Ziploc bag full of silica packets and cylinders I had saved. Five days later I took it out, and it was good as new. It's still working perfectly, some 8 months later.
How many cells are in a battery?
According to WikiPedia (http:/en.wikipedia.org/wiki/Rechargeable_battery), the nominal cell voltage of a Lead Acid wet-cell battery is 2.1 volts, this implies there are 6 cells in a 12 volt Lead Acid wet-cell battery.
What was Benjamin Franklin's most famous experiment?
Benjamin Franklin Rocks Benjamin Franklin (January 17 [O.S. January 6] 1706 - April 17, 1790) was one of the most important and influental Founding Fathers of the United States. A noted polymath, Franklin was a leading author and printer, satirist, political theorist, politician, scientist, inventor, civic activist, statesman and diplomat. As a scientist he was a major figure in the history of physics for his discoveries and theories regarding electricity. He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and a musical instrument. He formed both the first public lending library and fire department in America. He was an early proponent of colonial unity and as a political writer and activist he, more than anyone, invented the idea of an American nation[1] and as a diplomat during the American Revolution, he secured the French alliance that helped to make independence possible. Born in Boston, Massachusetts, Franklin learned printing from his older brother and became a newspaper editor, printer, and merchant in Philadelphia, becoming very wealthy, writing and publishing Poor Richard's Almanackand the Pennsylvania Gazette. Franklin was interested in science and technology, and gained international renown for his famous experiments. He played a major role in establishing the University of Pennsylvania and Franklin & Marshall College and was elected the first president of the American Philosophical Society. Franklin became a national hero in America when he spearheaded the effort to have Parliament repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco-American relations. From 1775 to 1776, Franklin was Postmaster General under the Continental Congress and from 1785 to 1788 was President of the Supreme Executive Council of Pennsylvania. Toward the end of his life, he became one of the most prominent abolitionists. Franklin's colorful life and legacy of scientific and political achievement, and status as one of America's most influential Founding Fathers, has seen Franklin honored on coinage and money; warships; the names of many towns, counties, educational institutions, namesakes, and companies; and more than two centuries after his death, countless cultural references.
Can you put plate in microwave oven?
It all depends on the construction.
Most plates made of pottery are OK as long as they do not have design containing metal. Some decorated plates have a gold stripe around the edge or in the design, avoid these. It is best to use cheap, white or plain plates.
Plastic plates are OK.
Why should there be violent video games?
Absolutely not. Humans are violent in nature at times, and movies are a form of self expression. It is much more safe to have violence expressed and enjoyed through movies than to have it actually acted out in real life.
Which big screen TVs are better lcd or dlp?
Hi,
They're both good and at the same time, they both have their specific problems, depending on the manufacturer, size of screen and intended uses.
The LCD sets are becoming higher in resolution and are now comparable to the dlp sets. What I would suggest though, it that you decide which one you like looking at best and then at least decide on what type, LCD or DLP you'd rather have.
Keep in mind that the big box stores spend a lot of money on making sure the TV's displayed in the showroom display the highest quality picture. That's usually a high definition DVD or at the least, a HD satellite feed. Chances are that when you get it home, and unless you have all HD equipment, you'll not see the same picture quality you saw in the showroom.
With all that being said, this is where you have to do some homework. Check Consumer Reports, keeping in mind that they usually rate the new models and product's service history hasn't been established since the TV's are so new. Also check 'blogs and answer boards on the internet. Usually there, you'll hear about TV's that are a year old or older. Why do that? Because the manufacturer's past product lines and complaints could be a good guideline on what to expect.
Once you've gathered all your information and have made your decision, do one last thing: BUY THE EXTENDED SERVICE CONTRACT! The costs to have service come out and the costs of the parts could prevent you from being able to repair your set once the factory warranty runs out. The parts for today's TV's are very expensive and sometimes as much as the original cost of the TV.
Hope this helps,

He did not invent the iPad.
And if you mean him being the first, he wasn't either.
The iPad was created to show the people of Microsoft what a real tablet can do. In response to when the tablet was introduced by Microsoft in 2002.
How did Percy Spencer invent the microwave?
When he was testing radio transmission using microwaves, he observed that one of his chickens was cooked to perfection. He realised that this was a very energy efficient way of heating things so he thought that he would put it to good use.
Who was the first person to the invent the light bulb?
The 1st electric lamp was built by Humphry Davy (an Englishman) in 1809. Thomas Alva Edison improved the invention and based his improvements on a patent he purchased from inventors Henry Woodward & Matthew Evans who patented their electric lamp bulb in 1875.
Sir Joseph Wilson Swan produced an early electric lamp (1860), and in 1880, independently of Thomas Alva Edison, he produced a carbon-filament incandescent electric lamp.
Thomas Alva Edison (February 11, 1847 - October 18, 1931) was an American inventor, scientist and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric lamp.
Can you use a TracFone sim card in a boost phone?
No you cannot. AT&T uses a GSM network and Boost uses iDEN and the two are not even remotely compatible. The Boost SIM card can be used for international roaming but it will not work with GSM networks in the US. It will not work either way, a Boost SIM will not work in a GSM device and a GSM SIM will not work in a Boost device.
How do you convince your parents to get a 3ds?
Tell her playing an instrument is good for you, because it actually is! It teaches discipline, is a hobby (helps you not get bored and do other things which are inappropriate it's fun. I'm pretty sure you get U-Cast points (I think they help you get into universities) for doing grades. Tell her that. Don't forget you will look cool! Many more reasons for playing an instrument by simply doing a quick search on Google or something.
How much does a DVD player cost?
A DVD home theater will greatly enhance your enjoyment of movies at home. I've seen prices ranging from about $60 to more than $3000, so examine the features carefully to get what's right to fit your needs.
What sort of instrument or tool does a conducter use to guide an orchestra?
A conductor leads the orchestra with a baton.
How do you mystery gift shaymin?
Its impossible now as the date is gone to download it, but if you still want to know, you have to go to mystery gifts and download by wi-fi then you get a special item at the shop from a man in a green suit. Then you have to use it and then you have the chance to catch shaymin, and if you want to and have the right item then give it to shaymin to make it turn into shaymin sky.
What is the purpose of a variable resistor?
A variable resistor is used in cicuits to vary the magnitude of resistance passing through the resistor. It is commonly used to change the value of current across a circuit to find relationships of current and voltage.
In a rechargeable battery system what is the discharging reaction?
Discharge cycle is the rate at which a battery i used to do work it changes with the load. Charging cycle is the time required for the same battery to reach a point whereas is ready to do work again, BOTH RATES ARE SET BY THE BATTERY MANUFACTURE FOR OPTIMUM LIFE EXPECTANCY.

What are the disadvantages of microchips?
First, although you hear the term a lot in movies and popular magazines, the term "microchip" is not used a lot by engineers and chip designers, who generally use the more accurate term "integrated circuit" or "IC" for short, or more informally, just "chip". The term "chip", without the micro, is derived from the stage of IC fabrication where the finished wafer is cut into tiny IC-sized pieces with a very fine diamond saw, producing "chips" of the wafer the way a beaver might turn a tree into chips by gnawing on it.
In general, there are a number of advantages of integrated circuits over constructing the same circuits out of individual ("discrete") components. Here are a few, although by no means all of them:
1: An IC is very much smaller than constructing the same circuit out of discrete parts.
2: ICs are less expensive, sometimes very much less expensive, than a discrete part solution
3: Because ICs are smaller and more densely packed, the lengths of the connections between the components is very much shorter. This allows the circuit to run faster, because you have reduced the signal propagation time and connection capacitance.
4: Since you don't have to drive a wire load between components, the transistors making up logic functions can be smaller and thus faster as well.
5: It's easier to heat sink the waste heat out of a single chip instead of millions of components, generally. Sometimes the heat dissipation of a single chip can present challenges, as with a modern microprocessor.
6: All the components on a chip tend to share similar characteristics. This means that the transistors, resistors and occasionally capacitors on the part are matched devices by the nature of the fabrication techniques. This can be nearly impossible to achieve with discrete devices.
7: Components on a single part in general track with temperature changes during operation, which can again be nearly impossible to do with discrete devices.
8: A chip is physically much less fragile than a large assembly.
There are any number of other advantages/disadvantages, but these are the ones that come immediately to mind.
A CB radio is a wireless transceiver that operates on the frequency band called Citizen Band, CB. This band has been reserved for the public. In some countries license is required and in some countries no license is required to operate CB radio. The maximum power limit is 5 Watts. There are 40 channels around 27 MHz in this band.
