The Internet
A global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols. – The Oxford Dictionary
During our evolutionary journey from “Homo erectus” to “Neanderthal” and then to “Homo sapiens”, we have come a long way. Because of our continuous quest for more amenities and better standard of living, we have been able to invent and discover many new things. The nineties witnessed a major revolution with the invention of the first electronic digital computers. Till then, the term Internet was practically unknown to most people. However, today, the Internet has become the most powerful tool for people around the world. With the advent of Internet, our earth has virtually reduced in size and has attained the form of a global village.

The Internet can be explained as a network of computers, designed to receive and send data in the form of e-mails, blogs, webcasts, etc. To put it simply, it can be likened to a super-massive server, armed with a plethora of information which is used by billions of people simultaneously. The Internet is basically “a network that connects other, smaller networks”. All modern technologies are connected by the Internet, thereby leaving no stone unturned. This digital world can be a playground for some and a battlefield for others.

The Internet has become an indispensable business tool, which has helped bring the world closer. Receiving news from across the world, accessing knowledge resources, and shopping online are simply a click away. The Internet has tremendous potential and a lot to offer in terms of services. However, like every other innovation in science and technology, the Internet comes with its own advantages and disadvantages, which have been discussed in this

What are Some Disadvantages of Nanotechnology

The National Nanotechnology Initiative, defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This technology is about controlling matter at an atomic and molecular level. Nanotechnology is expected to be helpful in the production of new materials. It can prove to be useful in a variety of fields like electronics and medicine. But we need to look at the dangers it may pose to the life forms on Earth, and the societal implications it may have. Here is a list of some disadvantages of nanotechnology.

➡ According to a discovery, silver nanoparticles used in socks to fight foot odor, if released into water, can be detrimental to its purity.

➡ Silver nanoparticles are bacteriostatic, which means they limit the growth of bacteria. This may result in the destruction of bacteria that help in breaking down the organic matter in water treatment plants.

➡ Recent research has revealed that some kinds of carbon nanotubes can prove as harmful as asbestos inhaled in fair quantities. They may cause mesothelioma.

➡ The process of manufacturing nanomaterials results in the release of certain waste products. They can float in air or even penetrate animal and plant cells.

➡ Nanoparticles have large surfaces. This makes them susceptible to get absorbed by macromolecules in an animal’s body.

➡ As the particles are very small in size, they are more readily absorbed by the human body. Their behavior depends on their shape, size, and surface reactivity. They may lead to overload on phagocytes, resulting in weakening of the body’s defense mechanism. They may also react with processes in the body and affect the functioning of body organs.

➡ The other difficulty is that, owing to the variety in these particles and given the many factors on which their behavior depends, it is not

Does My Computer Have Bluetooth?

Just the word Bluetooth sounds so modern and futuristic, it kind of gets you to think of a cute little blue alien, almost like E.T! It’s a far simpler yet an extremely useful little invention (from our very own planet Earth!), that has in many ways made our lives a lot easier. Since its conception way back in 1994 by the giants in communication technology, Ericsson, it has found its way into almost every gadget conceivable. Bluetooth is essentially a wireless technology which enables you to transfer data seamlessly between two compatible devices (newer versions support more devices) over short distances (most effective within the line of sight of the devices). Over the years, this revolutionary technology has been tweaked and refined further, and is almost a standard feature in even the most basic phones and other gadgets in the market. The Bluetooth chip itself is extremely small, but has many diverse applications. This is the main reason most electronic companies, and mind you not just the big names, have received this invention with open arms, and have incorporated it into their many devices.

Uses in Computers
Bluetooth also finds its many uses in the modern computer, mainly to transfer files and other data, to-and-fro from the computer to another Bluetooth-enabled device like another computer, a microphone, a smartphone, music player, television sets, and many such devices. For instance, if both the devices have a compatible Bluetooth chip, you can easily stream movies and other images from your computer onto your TV, all with the touch of a button. You can even make calls or listen to music wirelessly using a Bluetooth headset, without the world around you knowing what’s happening (although your loved ones might just get a little worried when you waltz around the house without any

How to Connect Bluetooth Devices

Bluetooth is a wireless technology that can be used for transferring data over short distances. The typical range within which data can be sent from one Bluetooth device to another, is 100 meters. These devices operate in the radio frequency range. The typical frequency of a Bluetooth device is 2.4GHz. It is designed to provide a simple, easy and secure way of data transfer, in a wireless and quick way.

Connecting Bluetooth Devices to your Computer

Say you want to use a wireless keyboard with your computer. The keyboard will connect to your computer using Bluetooth. If your computer has a built-in Bluetooth antenna, then no additional hardware is required. If it doesn’t, then you will need to use an external Bluetooth USB adapter or dongle. This adapter acts as a plug-and-play antenna, that will allow your computer to pick up the radio signals. Once you install the adapter on your computer, your computer will be Bluetooth-enabled, as long as the adapter is plugged in and turned on. The following steps illustrate connecting your computer to a smartphone in different ways, based on operating system model.

Advantages of Nanotechnology in Medicine

A nanometer is a value that equals to one billionth of a meter. Working at such a minute level has lots of advantages over conventional technology. Nanotechnology deals with application of devices and other tools that range, roughly between 1-100 nanometers in size. Seemingly impossible tasks can be easily performed with the use of nanotechnology. It is however, important that this technology becomes easily accessible for average users. Cost-effectiveness is a factor that would play an important role in popularizing nanotechnology, so that average people can enjoy the various benefits of nanotechnology, more so in the field of medicine.

Benefits of Nanotechnology in Medicine

The use of nanotechnology is ever-expanding in today’s technologically advanced world. This form of technology has many advantages over existing ones in many fields and medicine is one of them. There are numerous devices and mechanisms developed with the aid of nanotechnology that can help cure diseases/disorders in a much better and more efficient manner. The usefulness of nanotechnology can especially be seen in the treatment of cancer. Radiation therapy used in cancer treatment requires accurate targeting of affected cells. Today, nanotechnology is transitioning through the nascent stages of development; however, it is also making rapid progress in the field of medicine.

Repairing Body Cells Becomes Easy
Nanotechnology is used in the construction of miniscule devices and robots (nanobots) capable of entering the human body and performing a variety of operations; cell repairing one of them. These miniscule devices, developed with the help of nanotechnology, are also referred to as molecular machines. These machines can efficiently carry out repairing of cells, since they can distinguish molecules of one type of body cell from those of another. Earlier, it was not possible to repair body cells individually, however, nanotechnology has made it possible. Damaged heart tissues can be

History of Nanotechnology

The field of nanotechnology is of tremendous importance in the production of devices of many kinds. This field has been intensely researched and speculated about. It is the technique of building or making things with atomic precision. When every atom is thoughtfully planned and arranged in the given scheme of things, it results in a super device with a lot of applications. Although, the development in this field is a recent phenomenon, the core concepts of this science were laid down, long back in the 1950s. Richard Feynman, a physicist and Nobel prize winner laid the foundation of this field, with his landmark address at the California Institute of Technology in December, 1959. He had proposed the idea of technology that would accommodate volumes of information on a needle point.

Conceptual Origins of Its Foundations

The concept of nanotechnology has been in use since ancient times, even when it was not defined. Vulcanization of rubber, paintings, and various other processes employed the use of its principles, even without realizing the greater significance of these techniques. One-billionth of a meter is one nanometer, which roughly amounts to ten atoms placed side-by-side. Devices which are precisely dealt in, or contain parts with the precision of less than 100 nanometers (nm) are included as the products of nanotechnology. James Maxwell had first made certain observations regarding the maneuvering of individual molecules, by utilizing the concept known as ‘Maxwell’s Demon’. The actual attempts of observing and measuring the particles were done by Richard Zsigmondy, through the analysis of gold sols. He was the first person to characterize and classify the size of particles in the nanometer range.

Irving Langmuir, who won the 1932 Nobel Prize in Chemistry, and Katharine B. Blodgett introduced the world to the concept of a monolayer, a layer of a material

Negative Effects of Internet on Children

Internet has proved to be one of the most innovative inventions for us. It has made its presence felt in every sphere of our life, be it economy, society, health care, spirituality, etc. Prominent among its benefits is the impact it has had on the education sector. Students can now gain access to innumerable research papers, apart from getting latest updates in the field of science and technology. But as they say, “With great power comes great responsibility”, Internet has created new challenges for the society and most threatening among these is the impact it has had on children. Internet addiction has been recognized as a disorder in many countries, and rehabilitation centers have been created to help people to get over it. The sad part of this whole phenomenon is that a large proportion of Internet addicts are youngsters, who are extremely vulnerable to its ill-effects. There are several advantages and disadvantages of Internet but in this article, we will focus on its negative effects.

Internet and Children

Internet Addiction Disorder
Although studies on this disorder are in preliminary stages, it has been established that children who spend most of their time on the Internet, show a peculiar kind of behavior which is marked by an urge to be on the Internet all the time, so much that the child may shun all activities and become immersed in the virtual world. Surveys conducted over the years have found that most people who suffer from Internet addiction disorder are young adults, who easily fall into the lure of exploring everything that is available on the Internet. In America alone, it has been estimated that around 10-15 million people are suffering from Internet addiction disorder, and this is increasing at the rate of 25% every year.
