Internet Addiction

Not only the adults but the children too have got addicted to the reckless use of internet. As per researches, the children up to the age group of 12 years are the worst affected. They are found to spend more than 5 hours per day on the internet, by just sitting in front of computer screens, like dumb beasts. And this prolonged sitting is causing adverse effects on their mental and physical health. 

This addiction sometimes reaches the levels of insanity. It is not wrong to get the knowledge and information through internet, but this curiosity leading to addiction is dangerous.

The first victim of this addiction is the eyesight, which gets blurred, because the children continuously look at the screens. While it is advisable to look at some other thing after every 10 minutes, or to change the focus of the eyes, or to close the eyes for a while.

It also causes headache, backache, indigestion, sleeplessness, fatigue, stiffness in the neck leading to spondilitis, stress etc. The development of these symptoms in childhood is likely to cause severe problems in later life. 

A little knowledge is a dangerous thing, and the new generation instead of getting information are generally found to see what they like. They search only those things which suit their tastes, whims and thoughts. For them it is a game, and they may learn even those things which they should know in adult age.

There are very few children who take the help of internet for doing their homework. But there are the chances that such children may too get swayed. 

The lonely children of working parents are the worst affected. They get a friend or a guardian in the form of internet, but here the child has full control on them. 

The social networking sites are becoming more dangerous for the moral makeup of the children. They learn how to lie, how to be vulgar, how to distort facts and how to humiliate others by becoming self- oriented. They become obdurate, and whimsical; and develop an attitude of “I don’t care”, and “to hell with everything”.

What are Pixels?

The digital pictures are made up of small parts. These pictures do not appear to be composed of fragments; rather they look complete in themselves. But on close observation it becomes clear that in reality the digital picture on screen is made of a collection of small spots called pixels.

The pixel scenes and matter together form a picture. But pixel is not a scale to measure the size of the picture in inches as is sometimes mentioned on camera pixels. 

The clarity of picture indeed depends on the number of pixels. The screen of computer monitor is made up of millions of pixels. The monitor has a depth in bit, which decides the number of colors that could be assimilated in its pixels. 

Every pixel acquires eight or the multiple of eight colors. If a pixel has 24 bits, then it can display the maximum of 1.6 million colors.

The pixel is considered to be the smallest unit of a picture, but in reality it is not so. The pixels are further made of small matter. A pixel in the computer monitor is made of three color points. These three points are red, green, and violet. These three colors could not be seen separately as they remain in mixed form in the pixel. 

The word megapixel is used in digital cameras and it is a bigger unit than pixel. The unit of megapixel improves the quality of camera pictures.
