Transport and Communication (Part-A)
Transport is a service to carry people and goods from one place to another. It can take place over land, water and air. Humans, animals or vehicles can act as the medium of transport. Transport is an organised service industry to satisfy basic needs of the society.
Several places or nodes are joined together by a series of routes to form a pattern. This pattern is known as ‘transport network’.
There are four major modes of transport. These are land transport, water transport, air transport, pipelines.
Land transport was revolutionalised with the invention of Steam Engine in the eighteenth century.
Railways became the most popular and fastest means of transport in the nineteenth century.
Water transport is the cheapest means of transportation among all as it does not require route construction. Oceans are connected with each other and are navigable with the help of ships of different sizes. It only needs port facilities at both the ends.
Pipelines are used extensively to transport liquids and gases. Water and cooking gas are also supplied through pipelines. 17% of all the freight per tonne-km carried through pipelines in USA. Oil wells connected to refineries in many parts of Europe, Russia, West Asia and India.
The most common mode of personal communication used today is the mobile phone. Internet is the largest electronic network on earth, which connects the remote corners of the globe. Satellite Communication connects the remote corners of globe. Cost of communication is the same for any distance via satellite. Cyberspace is the world of electronic computerised space and is also referred to as Internet.
