Computer is a boon to engineers. Computers helpthem to design structures eg: bridges, vehicles etc computer find applications inComputer Aided Designing (CAD), Computer Aided Manufacture (CAM), andComputer Aided Engineering (CAE).
INVENTION OF INTERNET:
People exchange valuable information through internet. One can reach anywebsite and learn anything. Children could consult internet and can clarify their doubts.Communications are developed in leaps and bounds. With the help of button the commonman can interact and chat with dear and near ones.
