Creation and production of memory chips
Intel has been on 18 Founded in July 1968 by Gordon E. Moore and Robert Noyce as the Moore-Noyce Electronics in Mountain View, California, after they had left Fairchild Semiconductor. Soon afterwards, was also recruited Andy Grove, who led the company in the 1980s and 1990s. The company's aim was to develop semiconductor-based memory for your computer and bring it to market. The highly integrated (Very Large Scale Integration, VLSI) of transistors on silicon was in the year 1968 still in its infancy, and Intel developed the MOS process for the manufacture of semiconductors.
The first product the company was a 64--Bit Schottky Bipolar RAM. It was introduced in April 1969 under the name "Intel 3101". Only in July 1969 with the Intel 1101 was the first SRAM chip, which was produced by MOS process, put on the market. But it was in October 1975 - yet after only half the originally estimated time - managed the first major leap forward: Intel released under the name "1103" before the first DRAM memory chip, which was based on the MOS process and the benefits of had to offer highly integrated. During the bipolar process only at high-speed devices the advantage enjoyed emerged as the preferred technology for MOS semiconductor manufacturing technology.
As farsighted integration strategist Gordon Moore was recognized as early as 1965 a trend that later as Moore's Law not only the history of Intel, but the development of the entire semiconductor technology decisively influenced.
Until the mid 1980s, DRAM was the main business of Intel. The growing competition from Japanese semiconductor manufacturers and the resulting decline in sales but led 1983 at the re-orientation of the business model. The success of the personal computer from IBM led Intel to focus now on microprocessors and DRAMs abandon production. One of the main suppliers of Intel owns the Taiwanese company Foxconn.
Application of supercomputers
The cost of a supercomputer from the TOP10 now stands at a very high double digits, often already digit million euro amount. Upwards are no limits. Planning for the new standing in the field by 10 supercomputer PFLOPS are currently almost 700 million euros budgeted. These huge amounts of investment is inevitably the question of what these are needed very expensive equipment and whether the investment in the development of such a device, except for pure prestige, profitable.
Today's supercomputers are used mainly for simulation purposes. The more realistic a simulation of complex relationships, the more processing power is needed in the rule. The advantage of the supercomputer is also that they can take account of their extremely fast and large computing power ever more interdependent. This then allows the inclusion of wider still, often inconspicuous secondary or boundary conditions for the actual simulation, and also guarantee a more meaningful overall.
The current main areas of the supercomputer encompass the areas of biology, chemistry, geology, aerospace, medicine, weather and climate research, military, and physics.
Except for the military, which operates mainly military simulations to identify the areas in that we are dealing with very complex systems or subsystems that are linked to each other far-reaching measure. Thus, changes in one subsystem, usually more or less strong impact on adjacent or connected systems. Through the use of supercomputers, it is always easier to take into account many of these consequences, or even to predict, which could already far ahead of any countermeasures are taken. This applies for example in simulations of climate change, the predictions of earthquakes or volcanic eruptions, as well as in medicine in the simulation of new drugs on the organism. (However, logically, such simulations are only as accurate as it allow the programmed parameters and models for the calculation.) The huge amounts of investment in the steady increase in FLOPS and thus the development of ever-faster supercomputers, especially with the use benefit and the possible " knowledge advantage "is justified for humanity, not from the aspects of the general technological progress.
Construction of super computers
Since can not build any fast processors, are all high-performance parallel computers. A parallel computer is a computer that will be distributed simultaneously in the operations on multiple CPUs to increase the operating speed. Be tuned for optimal utilization of a supercomputer, the programming so as closely as possible on the individual parallel processors.
Supercomputers are now generally conceived as a vector or Skalarrechner calculator. They are based on different processor architectures. Vector processors (or vector computers, array processors called) perform a calculation simultaneously on many data (in a vector or array) from. Skalarprozessoren other hand, can process only a Operandenpaar per command. Skalarrechner therefore often based on thousands of standard processors that are networked together) (computer cluster.
Originally, the outstanding performance by maximum utilization of available technology was achieved by designs were chosen that were too expensive for large volume production (eg, liquid cooling, exotic materials and components, compact design for short signal paths), the number of processors was rather low. For a long time to establish more so-called clusters that are interconnected in which a large number of (mostly cheap) individual computers to a large computer. Compared to a vector computer nodes in a cluster have their own peripherals and only its own local memory. Clusters use standard components, so they initially offer cost advantages over vector computers. But they require a far higher programming costs. It is examined whether the established programs lend themselves to being distributed across many processors. Used programming languages include Fortran and C.
Closely associated with the term, the Cray supercomputer. It is named after its founder, Seymour Cray, and made the first supercomputer in the 1970s. The first Cray-1 supercomputer installed officially abolished 1976 130 mega-flops. (For comparison, a normal PC can now run multiple GigaFLOPS.)
Supercomputer or a super computer is a high performance computer is working at the time of its introduction in the top performance range achievable. It does not matter, based on which construction of the machine. A typical feature of a modern supercomputer is its large number of processors that can access to shared peripherals and a partially shared memory.

Various ways to open a task manager
Increase The Amount of Virtual Memory Used by XP
Virtual memory is a small portions of a hard drive space is converted to RAM. This is useful for computers which use more physical RAM than is available. Windows XP allow the user to change the amount of virual memory used. By default, the system determines the amount automatically. It is possible to change this to a set amount. It can be a good idea to do this for better performance. Here are the instructions setp by step, along with suggested settings
► Click 'Start'
► Click 'My Computer'
►Click 'View System Information' under 'System Tasks' (If you can not see this option then click 'System Tasks' to collapse the menu). This will open the System Properies window. Alternatively, you can go to Control Panel and open 'System'.
► Click the 'Advanced' tab
► Click the 'Settings' button under 'Performance'. This opens the Performance Options window.
► Click the 'Advanced' tab.
► Click the change button under 'Virtual Memory'
► Under 'Paging file size for selected drive' select the 'custom size' option.
► In the box next to where it says 'Intial size (MB) the best number to enter is 2X the amount of physical memory currently in your system. For example, if you have 512 MB of RAM you would enter 1024 in this box.
► In the box next to where it says 'Maximum size (MB)' enter the same number
► Click 'OK'
► Click 'Apply' on the previous window
► Click 'OK'
► Click 'OK' on the previous window
If any program crashed in windows XP it will show error report
We can avoid the error report to show by following simple steps.
What is error report(A box appears with a option send report or dont send options when software did'nt closed properly)
Open control Panel
Open Performance and maintenance(available in category view)
Then open system
Slect advanced tab
Error report button will be available there(button box at bottom of advanced tab)
Open it and select disable error reporting
click ok
Here after if any software trashes no error report will be shown to you

Create hidden user account
►This trick allows an account that is normally displayed on the Welcome screen to be hidden from view. To log on using the account it is necessary to use the Log On To Windows dialog box similar to the one in Windows 2000 i.e. press CTRL+ALT+DEL twice.
►Start-> Run-> Regedit
►Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\UserList
►MODIFY/Create DWORD Value of Data type REG_DWORD Named [Type Name of Account to be Hidden]
Setting for Value Data: [0 = Account is Hidden / 1 = Enabled]
►Exit Registry / Reboot
►While the account is hidden on the Welcome screen, note that the account profile will be visible in C:\Documents and Settings or wherever user profiles are stored as well as in Local Users and Groups.
Useful Tips for your computer:
►"at time shutdown -s" - we can shutdown computer without scheduling software
just replace time by some time such as 08:00(Railway time so dont use am or pm or change setting of ur time in ur pc to 24 hours from 12 hours) and see the magic
example:- type following in run "at 08:00 shutdown -s" then computer will be turn off at 08:00
►"shutdown -a" - to abort the scheduled time
►If u want to abort u shud do it before scheduled time which you have set.
Shows your pc processor name as you want:
►GO TO START>RUN>TYPE REGEDIT
►HKEY_LOCAL_MACHINE->HARDWARE->DISCRIPTION->SYSTEM->CENTRAL PROCESSOR
►RIGHT HAND SIDE RIGHT CLICK ON PROCESSOR NAME AND STRING AND THE CLICK ON
►EDIT AND WRITE WHAT EVER YOU WANT OR NAME IT as LATEST processor OR MORE
►HEY FRNDS DO REPLY IF U LIKE THIS TRICK
