The most popular mainframes are those which are manufactured by the IBM. They are the large systems which they started producing them in 1952 and are successful till date. Today the IBM mainframe means the systems which have the basic design of the IBM system/360 model. The IBM system/360 model was the compact model which could be used both for the scientific and the business purpose. It has been named system/360 to state that it includes all the aspect of the computer system i.e. 360 degrees. It had systems which were both upward and downward compatible. Also they had protection for the memory which could provide the security to your data. The newer versions of the mainframes have the extended addressing schemes to 24 bits from 18 bits.

The mainframes have been continuously evolving since they were developed. They have their own different characteristics which make them different from the others. They are capable of running more than one operating systems in one. This allows the virtual concept to function in the mainframes.

The Harry Potter series can be regarded as the most popular fictional series yet. Being a Harry Potter fan myself I remember how emotionally attached I was, and still am to this series. Every single book from the Harry Potter series has helped me come out of my shell and slowly mature into an adult. This series has influenced not only my generation but also the one before me and will hopefully influence many more. Not only is the story amazing, it also involves the reader by attaching the story to the readers life, because there comes a point during the story where the reader can put himself in the characters shoes.
The basic philosophy of The Harry Potter series is that it brings out the inner child of the reader, it is not socially acceptable to bring out ones emotion in the real world, so the reader then in turn hides his inner child in a corner of his mind and forces himself to grow into a mature adult for the sake of society and to be socially acceptable. Harry Potter brings out your inner child, because you can actually relate to all the happiness, grief, love and sadness which the characters suffer. Most people say that The Harry Potter series is for groups of all ages, but its not, its for everyone.
They say that whatever you do, you learn something new. And I strongly agree because after reading every book released in The Harry Potter series I have learned something different and new every time. It is amazing and beautiful how J.K. Rowling has made this series a big part of the life of the reader. Every time you read one of the books you learn something about your life and what you learn in turn affects your life by making you better and more mature than you were. The first book from the series The Philosophers Stone makes the reader believe, it makes the reader believe that there is always hope no matter how bad life is. It makes you believe that there are miracles in this world and that no matter what kind of hardship you go through you will always have friends by your side to help you out.

Another reason as to why you should use VPS is because you can control your hosting remotely. The desktop can be used and can give you complete control over you VPS. There is an administrative control panel that can be used to control the VPS from your desktop.
