•  Most of the businesses are buying and selling products through online mode - e-business or e-commerce.





















        Science and Engineering
        Engineering  involves  knowledge  of  science  and  mathematics  in  the  development  of  new  technology.  Powerful
        computers are used to simulate dynamic processes in Science and Engineering. Some of the common applications are
        listed below:
        •  Computer controlled robots are designed to do tedious and difficult tasks in almost all the fields.
        •  Mainframes  and  supercomputers  are  used  in  scientific  calculations,  weather  forecast,  defence  services  and
          astronomy.
        •  Doctors and microbiologists use computers to do detailed analysis of chemical balance inside the human body and
          helps in the diagnosis of different types of diseases.
        •  Satellites are the backbone of communication. It is of great importance in astronomy and space technology.
        •  Visual 3D display of the object images through software tools for advanced study and analysis.
        •  Computer-aided designs and manufacturing is used to design and manufacture  products  or machines used in
          different fields.





















        Agriculture

        Agriculture is the main source of livelihood in India. So, agricultural development is utmost important for our national
