Introduction to Cloud Computing

What is cloud computing?

Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. In other words, Cloud computing refers to anything that involves delivering hosted services over the internet and encompasses any subscription-based or pay-by-use service that, in real time, extends IT’s existing capabilities.

In general, cloud computing customer avoids capital expenditure of the company thereby also reducing the cost of purchasing physical infrastructure by renting the usage from a third party Provider. The companies devour the resources and pay for what they use. Many cloud-computing offerings use the utility computing model, which is similar to traditional used services like electricity are consumed, while others bill on a subscription basis. So sharing “unpreserved and intangible” computing power among multiple customers can improve operational rates. A side-effect of this approach is that the overall computer usage has risen severely because the customers do not have to engineer for peak load limits.

The most common example of cloud computing is yahoo mail or Gmail. You just need an internet connection to send emails through them. There is no need of server or any software to use them they are simply available on internet.  The major benefit of cloud computing is it has reduced the cost or capital expenditure of the companies. The company needs to pay for what it has used and upgrades are also done automatically.

Segments of Cloud Computing

Cloud computing has three main segments which are as follows:

• Applications
• Platform
• Infrastructure

Each segment serves different products for businesses and individuals with different purpose. Get cloud computing ppt slides to male attractive powerpoint presentation on cloud computing.

Applications – It is based on, o demand software services. On demand software services come in different varieties. They vary in their pricing scheme and how the software is delivered to the end users. In the past, the end-user would purchase a server that can be accessed by the end user over the internet.  Salesforce.com (CRM), Google (GOOG) and NetSuite (N) are some of the companies which provide on demand software or SaaS business.

Platform – The platform segment of cloud computing refers to products that are used to deploy internet. Net Suite, Amazon, Google, and Microsoft have also developed platforms that allow users to access applications from centralized servers. Google, Net Suite, Rackspace cloud, amazon.com and salesforce are some of the active platforms.

Infrastructure – The third segment in cloud computing, known as the infrastructure, is the backbone of the entire concept. Infrastructure vendors’ environments such as Google gears allow users to build applications. Cloud storage, such as Amazon’s S3, is also considered to be part of the infrastructure segment.

What is Nanotechnology and uses of Nanotechnology?

What is nanotechnology?

Nanotechnology, shortened to “nanotech”, is the study of the controlling of matter on an atomic and molecular scale. Generally nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension and involve developing materials or devices within that size.

A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.

In its original sense, ‘nanotechnology’ refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.

According to physicist Richard Feynman, Most of the work is being done today that carries the name ‘nanotechnology’ is not nanotechnology in the original meaning of the word. Nanotechnology, in its traditional sense, means building things from the bottom up, with atomic precision. To know more on nanotechnology click here for nanotechnology ppt presentation.

Uses of nanotechnology

Nanotechnology can be used in different spheres of life and it is being used in about 5oo everyday products. Click here to get nanotechnology ppt slides template that can be used in seminars and conferences conducted on nanotechnology.

Nanotechnology in Medicine – Researchers in medicines are developing customized nanoparticles as the size of molecules that can directly deliver drugs to the diseased cells in the body. When this method is perfected than it will reduce the damaged treatment such as chemotherapy does to the patient’s healthy cells.

Nanotechnology in Electronics – Nanotechnology increases the capabilities of electronics devices while reducing their weight and power consumption.

• Improves display screens on electronics devices.
• Increasing the density of memory chips
• Reducing the size of transistors used in integrated circuits

Nanotechnology in Electronics – Nanotechnology may hold the key to make spce flight more practical. Advancements in nanomaterials make lightweight solar sails and a cable for the space elevator possible. By significantly reducing the amount of rocket fuel required, these advances could lower the cost of reaching orbit and traveling in space.

Nanotechnology in Food – Nanotechnology will have great impact in terms of food. Companies are making nanimaterials not only in the taste of food but also in food safety. So nanotechnology will help in delivering benefits in food.

Apart from science electronics, food and medicine it also is also used  in fuels, better air quality, solar cells, batteries, cleaner water, chemical sensors, fabric and sporting goods.

Thus, nanotechnology is doing great in all spheres of life by making things simple and more useful.

As lot of researches is going on nanotechnology ppt templates are also available on internet. Click here to get nanotechnology ppt for seminars if you want to give any presentation on nanotechnology.
