2. COVID19 is announced as pandemic by WHO and they are tracking the data of patients for reporting purposes. UNICEF wants to collect information from all over the world and keep this communication secure. Protocol layering is an integral part of communication system which divides complex tasks into parts and make them comparatively simpler. Plan a protocol layering for this communication. Draw the layer flow diagram and explain the purpose of each layer in the process. Protocol layering must be different from TCP/IP or OSI Protocol. Question No. 2: Answer the following question? (20) 1. LED TVs have become integral part of university's receptions. You are required to select best of the below given TVs to display departmental news at the reception of the department. Higher the bit rate better the TV quality is. Support your selection with calculations. (Note: Assume random but different frame rate for each TV.
