What is the most powerful generation of computer?
In simple terms, the most powerful generation of computers will always be the latest generation of computers. Supercomputers are at the top in terms of sheer processing power, followed by mainframes, desktop microcomputers, mobile microcomputers and mobile telephones at the bottom. There is little point in comparing these with each other as their measure of power is relative to their purpose. You can't carry a supercomputer around with you, so a mobile phone is more powerful in that respect, but it cannot predict the weather.
However, there is a type of computer that is potentially way more powerful than any supercomputer ever built. These aren't self-contained computers in the traditional sense, they are actually a network of individual computers that work in parallel towards a common goal. This is known as distributed computing, or grid computing, and the Internet is a prime example (it is the largest network in the world, after all).
Without getting too technical, the Internet is a distributed network of discrete computers. The backbone of the Internet is handled by a handful of servers providing essential services such as DNS. However, subnets (including ISPs) mirror these servers activities, thus distributing the workload throughout the network. This ensures reliability as there is no reliance on any one computer. However, every computer that has Internet access is also part of that network and therefore has potential to contribute towards the workload. Thus it is not unusual for an organisation to maintain its own DNS, for instance.
However, we can take the principal one stage further. With literally millions of separate computers all connected to the same network, there is a potentially enormous amount of processing power available. While you're reading this, take a look at your CPU activity. Unless you're running an intensive process in the background the idle process will often indicate 90% or more, which means you're only utilising about 10% of your computer's potential processing power. If you do a lot of browsing and very little else why not put that 90% to good use?
If you add up all the machines connected to the Internet at any one time, it's a safe bet that around 90% of them are idle. Distributed computing can take advantage of this potential processing power to solve highly complex problems or analyse data in a fraction of the time it would take just one computer by itself.
The most famous distributed computing project is probably the SETI@home project -- the search for extra terrestrial intelligence. While there have been projects that might be considered more useful (such as the search for a cure for cancer), the SETI project serves as a good example of the potential processing power available. Although active users are only in the region of 100,000 or so (100,000 processors, if you like), the average performance is reckoned to be in the region of 505 teraFLOP/s.
A FLOP is a floating-point operation and a teraFLOP is 1012 floating point operations. So 505 teraFLOP/s is 505,000,000,000,000 FLOP per second. While this is well short of the IBM Sequoia's estimated 16.32 PFLOP/s (1015 FLOPs), do bear in mind that 100,000 active users is just a small fraction of the Internet's total user base, and that the actual processing is only done during idle time. Therefore the potential processing power available is enormous, far surpassing that of the IBM Sequoia, the world's fastest supercomputer.

Why is there a eyeball with circle on computer?
It's not an eyeball with a circle. It's the power button either for the monitor or the tower.
What is the illustration shown in projectors?
I'm guessing what your asking is how projectors show an image. They have an LCD inside them which displays an image and a light shines through which projects it onto a wall.
hit I'm getting this too! Plus the weird electronic porno bongo music. :<
BWAHAHAHA, go into the task manager and look for possible programmes to close in processes if there are none in applications.
How do you make a computer monitor extension cable?
Do you have an electronics store nearby? Call them and say, "Hello, I would like to purchase a computer monitor extension cable."
How do you close all running file on computer screen?
All running files on a computer can be closed a few different ways. One is to pull them up and close them one by one, or the computer can be shutdown and restarted, or just restarted.Ê
Who is the inventor of first computer?
A lot depends on how you define 'computer.' For very early mechanical devices check out Abacuses which are truly ancient and still in use in some parts of the world; Pascal -- late 17th Cent; Leibniz -- early 18th Cent and Babbage in the early 19th Cent.
The modern computer is a result of the work of Turning in the 1930's thru the 1960's working with Von Neumann's teams at the Institute of Advanced Study at Princeton and the Los Alamos Lab in NM and Aberdeen Proving Grounds in MD. This was all part of the WWII weapons development effort.
This question covers a huge area of study and, every scholar has his own favorites as to who did what and when. PLZ note: This MY opinion.
Can Ford deactivate the on board computer if you are behind on your payments?
No. They can, however, repossess your vehicle
I would not recommend doing this if you're wanting to copy Operating system and all over to another computer. No. 1 it probably will not work because of driver and motherboard issues. No. 2 if it does work, (Windows is able to load adequate new drivers to get up and running) then you will probably still have major problems with conflicts, and other driver errors left over. I would suggest loading the other computer from scratch.
That advise was free now here's the answer to your question. There is a program called Norton Ghost that will allow you to duplicate a drive or partition to a second drive or partition. There are other programs like Drive Image Pro that do basically the same thing. You'll need to boot to a dos prompt and run the "ghost.exe" from a diskette or another drive partition. Once in the Ghost program you can select the drive/partition you want to copy, then you select the destination. This will be the blank drive you have. (By the way I neglected to say the clean drive needs to be placed in the system with the original hard drive in it.) After selecting the correct destination the software will proceed to duplicate the information to the blank drive. Once this process is complete you now have two drives with identical information on them.
1 What is the role of databases in computer-based information systems?
The role of databases in computer-based information systems is to offer a management platform. The database will have various controls to the information systems.
Work done by computer is more reliable than human?
That could be answered differently depending on exactly what is meant by reliable. If you mean able to do millions of tedious and boring calculations over and over for many hours without error, then the answer is computer. If you mean make difficult decisions about complex ambiguous issues and questions, then the answer is human. If you mean something else...
Universal Serial Bus is an output or an input?
USB ( Universal Serial Bus) serves both purposes...both output and input....when we copy something into a pen drive it serves as an output and when we view something from a pen drive it serves as an Input.
Explain the Elements of world wide web?
a) Accessibility to different features e.g. Video's, Images, Data, games etc….
How do you deactivate a pasted link when you just want the words not the link?
If you paste it into Microsoft Word, hold down "control" while clicking on it, and from the menu that pops up, choose "Edit Hyperlink." A window pops up, and click on "Remove Link."
Which types of cable has a single inner-core wire conductor and a wire-mesh outer conductor?
That is a description of an ordinary "coaxial cable". There are designators for various specific coaxial cables such as RG-58 and RG-59. See the link for more. Sounds like shielded RG-58 or RG-59 used respectively as listed above for cable TV or RG-59 for satellite TV. If the cable is as large as a human average finger it could be shielded 2-way radio cable which usually is run from the base station to the outside antenna.
Will a computer booted that has no jumper on the hard drive?
This question is highly dependent on the specifics of your hard drive. Some hard drives have jumper set ups where theres a setting that has no jumper. If that's your type of hard drive then there should be no issue. Either way the computer should boot regardless of jumper setup. It just may not be able to load the Operating System.
Explain the types of transmission in computer?
There are mainly three types of transmission modes : 1) Simplex : Information can flow only in one direction 2) Half Duplex : Information can flow in both direction but only 1 at a time can send and 1 can receive. 3) Full Duplex : Information can flow in both direction and both can send and rceive at a same time.
How do you stop deleting letters after you go back to fix a mistake?
I'm not entirely sure if I understand your question, but I might.
I believe you may have "overtype" enabled on the application you're using. This is typically enabled/disabled by pressing the "Insert" key on your keyboard.
