In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. • Appreciate the relevance and importance of standards, in general, and the OSI model, in particular. They are public transport and transport for non generic-use. Network architecture models separate specific functions into layers, which collectively form a network stack. Road transport carries more passengers and goods within localities because they are normally constructed to connect towns and villages where rail, air and water transports are absent. The latest demands on the transport network come from areas such as increasing RAN and mobile broadband service capacity, new 5G-enabled services and the dynamic deployment flexibility of the 5G RAN split architecture, with its tight transport characteristics. These form a dependable network for the movement of both the people and goods. Container ships carry most of the world's goods, while bulk carriers transport raw materials like coal or iron ore, and tankers transport oil, petroleum and other chemicals. , and Axhausen, K.
