Beware of your CELLPHONE

                     Recently I have made research on cellphone and how the radiation levels are going to affect our brain and on health.

First let us know about the radiation of cellphone and how it is going to measured.......

                The radiation levels of cellphone can be measured by a rate called Specific Absorption Rate (SAR), which means the rate at which the RF radiation is absorbed by human body. This SAR value is measured in terms of Watts/Kilogram(W/Kg).

                If SAR value of your mobile phone is more than 0.5W/Kg, then your brain and nerves are affected soon by radiation of your cellphone.To know the SAR value of your phone click on the below link

                     Finally I suggest you that, If you are talking more, then use phone model with SAR less than 0.5W/Kg or take measures like using headset........    

operating systems

                 Here i will discuss what is an operating system, what is the requirement of an operating system, what are the different types of operating systems present up to now, Requirements of installing a operating system, process of installing operating system, what are the required softwares after installing operating system.

The software used in windows version of softwares are portable. At first windows releases windows 95, then windows 98, windows 2000, windows xp service pack 1, windows xp service pack 2,  windows xp service pack 3, windows vista, windows 7, windows 8 (latest version yet to be released).

Requirements of installing OS:

                    After connecting all the components of PC. In order to install OS you are supposed to get bootable CD/DVD or bootable USB drive. This bootable devices have the type of OS you wish to install in your PC.
