Cloud computing for business applications

Advances in computer technology have increased levels of performance and productivity in companies of all sizes. Rapidly expanding data, and using the Internet along with greater storage capacity and a variety of electronic devices has brought a new era in networking capabilities. In the latest such technology is cloud computing.

What exactly is cloud computing? Through a service provider, cloud computing is the platform serves as a remote data center where users can access files safely through a large number of computers where there is Internet access. Is the solution to companies and individuals looking for an easy way to store and access the media from one device to another, and the ability to share them with others who have been granted access.

Network cloud computing may seem complex, but can be used by anyone. It is not necessary for end user to understand the complexities of infrastructure or system networking and how it works. It would be an interesting example applicable to comparable electricity where users access the service but not necessarily understand the systems and hardware components that provide the service.

A model which provides an environment where networks and applications can be shared and stored by many users with minimal effort. This interaction requires minimum service provider, and availability of computing resources, which can be shared upon request. This ability to store information about after many possibilities in small businesses. Without the need to keep your programs and files stored locally, anyone can now work on the touch pad or phone or laptop from anywhere, and share their files with anyone else in the company. Cloud computing can also be used as a backup and off-site storage of copies of important documents in case of restoration of data for computer repair.

Since the delivery of cloud computing providers of online business applications, and infrastructure, you can use these services without investing many resources. Particularly useful for small and medium-sized businesses, these services have the ability to stop outsourcing through internal tasks made more affordable, saving time and money. Provide initial costs low and full customization of support options, cloud computing has become a competitor in computer networking for small businesses.

This new system is still emerging, but technology will help to create a new generation of products and services. Many large corporations are investing resources, building infrastructure and explore cloud computing as a platform. Products and services that were not previously cost-effective options, applicable to many companies will be available through service providers. Sharing the combined resources will enable users to build real-time communications, collaboration and business partnerships project more efficient.

This will be a revolutionary computer networking platform advances in computer technology ultimately commonplace in companies of all sizes. Cloud computing was a strong start and promising, and definitely will have a lasting effect on the business environment, business practices and productivity.

Lee penny specializes in providing reliable computer network support for companies that want to improve productivity and profitability. With computer repair and support of information technology that sets the best for your work, you'll have to start worrying about the technology again.

Amazing Applications of Nanotechnology

The field of science which looks forward a boom every day is definitely, nanotechnology. It deals with particles that are very small in size( about 10^-9 m).The main idea upon which nanotechnology relies is that the original properties (either physical or chemical) of a substance gets changed when the size of the substance is reduced to nanoscale. Below given are a few interesting applications of nanotechnology...

? When water is simply allowed to flow through copper nanotubes, an emf is generated along the surface of the tubes( thereby generating current). The current produced is directly proportional to the speed of the water.

? Gold and silicon nanoparticles are red but their original colour in bulk state is yellow and grey respectively. These elements have their melting points 4 times while being in the nanoscale.

? Nanocrystals made of metals and semiconductors exhibit superior chemical, electric, optical, magnetic and mechanical properties.

? Photovoltaic cells (which generate current from solar energy), made up of nanoparticles absorb more energy than the thin film sheets of normal semiconductors.

? Within the polymer matrices of plastics, clay nanoparticles are embedded for additional strength (extra 100%) and reinforcements.

? Dendrimers are nano materials made with the structure of a bacterium (E.Coli). Its flagellum is used for quicker transportations through fluids and so dendrimers are used in the Smart Drug Delivery System in our body.

? Transistors made of semiconductors in nanoscale provide higher dielectric constant and electron mobility making them more efficient. Nanoelectronics is based upon such transistors and other devices.

? Recently, a programmable molecular computing made of enzymes and DNA molecules is been invented. It doesn't use any of the semiconductor devices.
Marvels from nanotechnology exist in both sides. It is wonderful as much as it is dangerous. Researches on the negative effect of the nano materials are taken into prime considerations before approving a technology. A few disadvantages are:

? High surface to volume ratio makes almost all nanoparticles highly reactive. And so, it is very doubtful that all reactions can be controlled to the required level.

? Certain nanoparticles in air can penetrate cells and tissues and can cause severe biochemical damage in functioning organs.

? Hydrocarbon nanoparticles (from pollution) can damage cardiovascular system.

? Nanoparticles of oxides and dioxides of metals cause DNA damage which may affect one's descendants (a heredity disease).

On enjoying the benefits of this immensely powerful technology, we must not let loose about the precautions we must take or follow. This doesn't mean research interest over nanoscience should reduce. Just that all factors are to be considered at an optimum level to gain most profits and least losses from it...
