Transportation involves moving goods from manufacturers to end users, while logistics manages the inward and outward movement of goods throughout the supply chain. There are various modes of transportation including air, water, railway, and road. Air transportation is the fastest but most expensive, moving lightweight goods quickly over long distances. Water transportation transports goods on water vessels and is cost-effective for bulk goods. Railway transportation moves goods on tracks between locations and is a cost-effective option for medium-distance cargo. Road transportation utilizes motor vehicles to move people and goods locally and provides flexibility but is limited by traffic.
