The vast network of roadways, railways, waterways and airways across the countries has linked each nook and corner of this world with the other. Transportation and communication have reduced not only distances but also the time taken for covering these distances. The time of travel is reduced considerably due to the presence of fast means of transport like Aeroplane and super fast trains. Due to communication facilities such as mobile phones, Emails, SMS one can talk and see and interact with people sitting thousands of kilometers away. The internet provides us with not only world wide interaction but also world wide information. The inter connectivity of people, services and institutional across the world has brought the world closer and closer making it a kind of global society, a global village.
