SUBJECT : DATA COMMUNICATION AND COMPUTER NETWORKING $5.$ a$)$ Differentiate between Synchronous and Asynchronous transmission. Why do we need proper Synchronization during transmission? Give an appropriate example. $(5$ Marks$)$ b$)$ Draw a hybrid topology with a ring backbone with three bus networks and two mesh networks. Discuss the consequences if a connection fails in the backbone. $(5$ Marks$)[$Total: $10$ Marks$]5.$ a$)$ Differentiate between Synchronous and Asynchronous transmission.
