How did dean kamen invented the first water purification device?
Dean Karmen didn't invent the first water purification device; he invented a simple water filtration device for use in rural areas of developing countries.
Compare the difference between pervasive computing and other computings?
First, let's look at what they mean. Ubiquitous means everywhere. Pervasive means "diffused throughout every part of." In computing terms, those seem like somewhat similar concepts. Ubiquitous computing would be everywhere, and pervasive computing would be in all parts of your life. That might mean the difference between seeing kiosks on every street corner and finding that you could -- or need to -- use your Palm handheld to do absolutely every information-based task. And, in fact, that's where the difference between these two types of computing lies. Pervasive computing involves devices like handhelds -- small, easy-to-use devices -- through which we'll be able to get information on anything and everything. That's the sort of thing that Web-enabled cell phones promise. Ubiquitous computing, though, eschews our having to use computers at all. Instead, it's computing in the background, with technology embedded in the things we already use. That might be a car navigation system that, by accessing satellite pictures, alerts us to a traffic jam ahead, or an oven that shuts off when our food is cooked. Where IBM is a leader in the pervasive computing universe -- it has a whole division, aptly called the Pervasive Computing division, devoted to it -- Xerox started the ubiquitous thing back in 1988. Ubiquitous computing "helped kick off the recent boom in mobile computing research," notes its inventor, Mark Weiser, who came out with the concept at Xerox's Palo Alto Research Center, "although it is not the same thing as mobile computing, nor a superset nor a subset." That means that people who use ubiquitous computing to mean computing anytime, anyplace -- to describe hordes on a street corner checking their stock prices until the "walk" light comes on or efforts to dole out laptops to all students on a college campus -- aren't using the rightterm. We don't really need to use either one. I'd be happy to call pervasive computing mobile computing, and to call ubiquitous computing embedded or invisible or transparent computing -- or even just built-in functions. Besides, until either ubiquitous or pervasive computing is anywhere and everywhere, those alternatives seem more accurate.
What does a computer do when you first turn it on?
The first thing a computer does when you turn it on is check the BIOS to see which device it should boot from. It then finds the bootloader on that device (usually the hard disk), and runs it. The bootloader typically finds the operating system and starts that. And the operating system does various things when starting, such as starting certain programs that are set to load on startup.
What is primary device?
Ooh..., tough one. You could say it is the user. But that is lame. You could also say processor, since no computer could work without one. My first computer worked with a 5¼" floppy drive, no hard drive, 256 kb of RAM and a 4.7 Mhz processor. No mouse either. The graphics were CGA and EGA.
How do you install a phase converter?
If you want to install a phase converter, there are specific directions that you must follow. First, shut off the electricity to the device. Next, install the converter in a dry and vibration free environment. Install a ground cable that will run from the device to the converter.
What is the first analog computing device?
The first analogue computing device was the human mind. Yes, it's true; the human mind is an analog device.
What is the first manmade computing device?

What was the first computing device?
wooden balls on hanger type wire I think and about 4 rows of 10 balls
When was the first PDA Palm device developed?
Palm Computing is known for its Personal Digital Assistants (PDA) devices. The device itself is essentially a handheld device which manages the user's information. Palm's first PDA device, the Palm 1000, was first released back in 1996.
First person to conceive of a mechanical computing device?
I recall reading some time ago that the earliest recorded mechanical computing device is the Abacus. The article indicated that the exact time was not determined, but that evidence showed that it appeared at about the same time in both China and in Persia.
Who is the first developer for computing math?
the first developer for computing math was the Arabian scintist alkhwarezmi
When was the first computer established?
The first computer on record was in the year 1822. This computer was the first automatic computing machine and was capable of computing several sets of numbers.
Some Cloud Computing Benefits?
There are a lot of cloud computing benefits that you can enjoy once you start putting all of your devices on the cloud. The first obvious benefit of cloud computing is that you will have constant access to all of your important information, even if it's stored on a device that you don't have with you at the moment. Second, it makes sharing information and getting in touch with people much easier than it used to be.
When was the transistor first used in computing?
1947
What to do if someone get interested in computing while doing physics degree?
Get the Physics Degree FIRST; THEN study Computing after graduation.
Was the computer invented in Switzerland?
No. Mechanical computing devices with any similarity with today's computers and the concepts behind them originated from the UK. The first electrical computing device originated in Germany. Then the British created the Colossus to break German codes during WWII, and after that, the ENIAC was created in the US. The ENIAC was faster and more flexible than the Colossus.
What is the symbol for First Trust ISE Cloud Computing Index Fund in NASDAQ?
The symbol for First Trust ISE Cloud Computing Index Fund in NASDAQ is: SKYY.
