Future of Technology
Technology is expanding faster and faster and the future seems limitless for such an important sector, which has many wondering what the future holds for the industry. Currently there are technically advanced developments in the field of computer hardware, computer software and even the Internet that will change the way we work.
The way computer hardware is made and its function will soon be changing. Right now, there are a couple of new developments in this area of the future of computer technology.
Holographic Storage Technologies:
The theory of holography was developed by Dennis Gabor, a Hungarian physicist, in the year 1947. His theory was originally intended to increase the resolving power of electron microscopes. The result was the first hologram ever made. The early holograms were legible but plagued with many imperfections because Gabor did not have the correct light to make crisp clear holograms as we can today given he needed laser light.
However, it wasn't until the 1960s that two engineers from the University of Michigan: Emmett Leith and Juris Upatnieks, developed a new device which produced a three dimensional image of an object. Building on the discoveries of Gabor, they produced the diffuse light hologram. Today, we can see holograms, or 3D images, on credit cards, magazine covers and in art galleries. Yet this unique method of capturing information with lasers has many more applications in the industrial world and is on the verge of revolutionizing data storage technology as we know it.
Currently, tests are being done on creating a commercially viable holographic storage system. This technology not only offers very high storage densities, it could access that data at very high rates, due to the fact that holographic methods read an entire page of data in one operation. While conventional optical storage techniques read and write data by altering an optical medium on a per bit basis, holographic storage records an entire interference pattern in a single operation.
Protonic Memory :
One of the biggest horrors of the computer age is to be working on a document not yet saved to the hard drive and lose everything because of a power outage or a system crash that forces the operator to shut down the computer. Attempts to create circuits that store the information when the power is interrupted have used high voltages, which quickly wear down computer electronic components, and have been expensive. Some scientists have applied for a patent on a prototype memory retention device that is inexpensive, low-powered, and simple to fabricate that may be the future of protecting vital data when suddenly lost without being save. To transmit data, the device uses embedded protons, which remain where they are when the power turns off, thus preserving the information. In devices such as DRAM's (dynamic random access memory), typically based on electron flow, the information is lost when the power is turned off.
According to a group of researchers calling themselves the Nanocomputer Dream Team, November 1st, 2011 is the day they'll unveil a revolutionary kind of computer, the most powerful ever seen. Their nanocomputer will be made out of atoms. Moving individual atoms around at will sounds like fantasy, but it's already been demonstrated in the lab. In 1989, scientists at IBM used an electron microscope to shuffle 35 xenon atoms into the shape of their company's logo. Since then a team at IBM's Zurich labs has achieved the incredible feat of creating a working abacus on the atomic scale. Nanocomputers, if they ever appear, will be extraordinary things. But if, like most computer systems, they have bugs, they could also be very nasty, as well.
Many of these next-gen interfaces will not have the user control the computer through commands, but will have the computer adapt the dialogue to the user's needs based on its inferences from observing the user. Most current user interfaces are fairly similar and belong to one of two common types: Either the traditional alphanumeric full screen terminals with a keyboard and function keys, or the more modern WIMP workstations with windows, icons, menus, and a pointing device.
An alternative model is emerging in object-oriented operating systems where the basic object of interest is the user's document. Any given document can contain sub objects of many different types, and the system will take care of activating the appropriate code to display, print, edit, or email these data types as required. The main difference is that the user no longer needs to think in terms of running applications, since the data knows how to integrate the available functionality in the system.
A major concern for creators of digital content, whether it's Web content, music, or movies on digital disc, is to protect their work from unauthorised copying and distribution. DataHiding is a technology that allows owners of content to embed data invisibly or inaudibly into other digital media, such as video, audio data, or still images. When the data is embedded, it is not written as part of the data header, but rather embedded directly into the digital media itself. This process changes the original digital data, but the change is so slight that it cannot be visually detected, and has no impact on the performance of the original data.
The beauty of DataHiding is that it gives content creators a powerful means of marking their digital creations without affecting the end user's appreciation of it. The embedded information does not change the size of the original data, and it survives normal image processes such as compression and format transformation.
These are just a few of the new computer technologies that might arise in the future and that are currently being tested to see if it works. While it may not, some still have the possibility of evolving into something else and still taking the future of computing to new heights. Those looking to learn about current advancements in technology can easily take IT training classes to increase their knowledge.
