Physical and virtual Values(Operating system Vs Human nervous system) Part-2

When we use operating system, we operate it with two kind of memory, or in technical way you can say that Operating system operate its application in two ways. One via physically and other opposite virtually. Physical memory used for storing the information. It works as a task. But the process to execute this task has been done by virtual memory. Our operating system creates a virtual operating system while we use any application, it access the data we provide it,  and if we allow it , then it save it on physical memory. Using this techniqe secures our Hard disk from getting corrupt.

Difference Between Task and process is that process is a dynamic entity. When we execute any work it start processing and when it finish the work and convert it into a product or value then we can say task has been complete. Task is a container of processes.

So in our real life I have seen so many things like that, like if I talk about our future, then go back 100 years ago. In the beginning of 20th century nobody would have predicted that we would use operating system to talk to show our photos, or to time pass also. Our system, internet everything has changed us. But if you go behind 100 years and tell somebody that you will be able to use machines to send messages from India to america, people will put you in mental hospital. So the thing is we had a dream a faith that one day we will accomplish our task with virtual dreams(processes). Not only I but everyone. 'I' means no one single can achieve his dreams, he need others to contribute, active or passive everyone helps everyone. By good deeds or bad deeds we all part of this whole universe. People die everyday and born everyday and we don't care for lots of people who are physically dead, but we care for our loved one who makes most of difference in our life. 
              What I want to say is that whatever we have in our mind or imagination via some processes we can make them physical. The thing that seemed impossible hundred years ago is now part of our daily life. A thing we cannot live without. All we need to do is to keep thinking new, don't care whether you will be wrong or people will criticize you. You just have to bring your imagination into real. As our prime minister Modi sir says,"We need to bring laboratory thing into reality." So from lab to real world its a hard process but once it get done, we feel nice we feel amazing. 
                                   For creating something physical we need it virtual, suppose in our imagination. That why -"Wisdom comes from imagination not knowledge."- Albert Einstein
