Advancement in Computer Technologies:
Since the introduction of the first computers the Computer technology has advanced at a very fast pace. Every single day a new innovation, a new concept is being introduced in the computer technology. The pace in the computer technology is so fast that if a person says about a task that it is impossible, a person in another part of the world is already working on it. These advancements have encouraged different companies to come up with their ideas and compete with the pioneers of the computer market.
Tablet PC’s: The latest and the best:
Tablet PC’s are the latest and the best form of computers. Users have found them and liked them a lot. A tablet PC provides in the true sense the portability and ease that the miniaturised computers have promised. Tablet PC’s, since their origin, have been made better and faster. A few companies have come up with some lightening fast and attractive tablet PC’s. These include Apples, Samsung, Amazon, LG and many others. All of them have tried to make the tablet PC’s faster and better. But if you are talking about the best in this field then there is no doubt only one and that is Samsung.
Samsung and Tablet PC’s:
Samsung has been the pioneers in producing Tablet PC’s. Samsung has always tried to give its customers the best. That is why latest processors and sleek stylish designs have been seen in Samsung’s Products. The latest in this field is the Samsung Exynos 5250 Chip. This 2 GHz Cortex A15 Exynos 5250 Chip is the latest and the fastest processor chip that has been yet made for the tabs. This dual core processor provides better speed and enhanced performance in the tablet PC. This design is better adaptive to 3D technology and provides a new maximum resolution of 2506x1600. Samsung says that this processor will be available in the market by the end of 2012.

At server level this chip can reduce the power level up to 45W. Even more! The Samsung 20nm DDR3 can reduce the temperatures of the server by almost 21° Celsius. And by this the server fan noise will also be reduced due to low heat generation.

Samsung’s all new 20nm class DDR3 and SSD is not just great
news for the processors but also for the planet. As Samsung is going all green with this new
mass production.
This semiconductor chip is more speed and less energy
device, not only consumes 38% less energy but is 3.5x faster than other
memories in use. It has a really high potential of reducing the waste of
energy.
At server level this chip can reduce the power level up to 45W. Even more! The Samsung 20nm DDR3 can reduce the temperatures of the server by almost 21° Celsius. And by this the server fan noise will also be reduced due to low heat generation.
This performance was shown not just for the new processors
but also worked the same with the older ones.
The company expects it market level to rise and the chip
would be made the part of every technological environment.
The company is also planning to make 4GB memory chips very
soon and then moving on to the 8GB, 16GB and so on.

Finger print recognition algorithm is used extensively in security related areas. For accessing any database, authenticating to any special services in your company or any other form of security service that use to ask about your ID cards or stuff like that previously.
Here we have provided the MATLAB code of the Finger Print Recognition Algorithm.
That takes the finger print as an image. The 'add to database' option lets you enrol your fingerprint into the database for future queries.
The 'match option then lets you match the finger print image with the database its going to have.
A user friendly GUI is also developed for this purpose with easily monitored buttons.
The attached file also have some fingerprint images for the testing purpose.

Computer Technology:
Computer Technology has advanced a lot in the past few
decades. We have seen some extremely eye catching and awesome computers being
made available in the market. Computers with awesome specification and
attractive body have made the use of computers easier and simple. To drive
these computers different companies have produced different operating systems.
Some in the line are Windows OS, Macintosh OS, Ubuntu, Linux, UNIX and many
others.
Operating Systems:
Operating Systems have been made better and better as the
years have passed. The best company and the one which is ruling on the computer
world is the Microsoft Corporation. Microsoft has given some extra ordinary and
user friendly OS to the computer users. Some of them being Windows 95, Windows
98, Windows NT, Windows ME, Windows XP, Windows Vista, and the latest in this
line is Windows 7. Windows 7 is considered to be the best and the most user
friendly OS in the line.
Improvement in the
Windows OS:
Microsoft has always been of the view point that the
consumers be provided with the best computer solutions. That is why the Microsoft
team is constantly in process to create such a product that is both safe,
secure and extremely user friendly. So to raise the bar even more a further
enhancement in the Windows 7 OS has been done and a new OS is going to be
introduced in the market by the Microsoft Corporation.
Windows 8: Safer,
Securer and Better:
Windows 7 was a huge success for sure, and to make the
things better Microsoft has come up with the latest OS, named as Windows 8. Windows 8 is being
interpreted as much better and secure than its predecessor. The actual release
date of Windows 8 is still unknown, but some sources say that Windows 8 Beta
version will be released in February in the next year. Users are anxiously
waiting for the release of Windows 8 and are hoping that it is better than Windows
7 (fingers crossed).

Evolution of
Computers:
Computers have become an integral part of life nowadays.
People all around the world use computers in some way. Calculators, Tablets,
Netbooks, PC, Laptops, PDAs and many other gadgets are some examples in which
we interact with computers. The evolution of computers started since the first
computer was invented in 1946. The first computer was just like a simple calculator
like in nowadays and but it covered an area of a whole large hall. Since then
the evolution started and both the speed and miniaturization were made better
and better. And it is due to that evolution that we see laptops and Netbooks and
the fastest computers in the world, “The Super Computers”.
Supercomputers:
Super computers are the fastest computers in the world. They
are huge in size as well as calculations. Super computers are used for highly
intensive calculations like weather forecasting, quantum physics, molecular
modeling and many others.
Speeds of
Supercomputers:
Super computers are extremely fast in doing these
calculations and have a capacity of calculating at very high rates. Speed of
super computers is measured in FLOPS (FLoating Point Operations Per Second)
with SI-Prefixes like Tera-FLOPS or TFLOPS (Tera is 1012), and Peta-FLOPS
or PFLOPS (Peta is 1015).
Fastest Supercomputer
in the World:
China has left America behind in the technology world that
has made the fastest Supercomputer of the world. Chinese named this computer Tianhe-1A.
This supercomputer has a speed of 2.507 PFLOPS. In other words it can perform
2,507 trillion FLOPS in the blink of an eye. This Chinese computer will take
the spot of America’s Cray XT5 aka ‘Jaguar’ which had the speed of 1.759
PFLOPS.
The Tianhe-1A was designed by the National University of
Defense Technology and will be constantly used for intense and large scientific
calculations.
