(i) source IP address in decimal.
(ii) destination IP address in decimal.
(iii) source MAC address for the frame in hexadecimal.
(iv) destination MAC address for the frame in hexadecimal.
(v) source port number in decimal. Hence, describe the contents of the data portion of the frame, naming the application layer protocol this segment is destined to.

(b) A Medical center consists of two buildings on a private land, separated by around 95 meters apart. In building A, there are 70 hosts, including servers and additional five Wi-Fi laptops for the medical staff. In the two-storey building B, there is a cyber-café of 10 hosts and Wi-Fi area, both for public use. Users in the cyber-café and Wi-Fi area can only use the Internet to surf. All other services are not allowed. The center uses a private internal network: 192.168.1.10/24. The center has a single connection Internet via an ADSL link from the ISP with the single public static address 202.123.21.144.

Draw the full network diagram and identify any required devices, transmission technology and media. Give the IP, subnet mask and gateway addresses for all devices and servers used. Include the configuration for 1 host each in building A, and B. Use proper design principles with emphasis on security and performance.
