Question

16 according to lecture,.edu in a domain name indicates: a governmental website a military organization an educational institution a business website 17 according to lecture, the primary challenge in green computing is: reducing overall energy costs improving internet speed reducing hardware costs minimizing data loss 18 according to lecture, udp is used for: slow data transfer real - time streaming encrypted communication guaranteed file reassembly

Explanation:

• For question 16: The domain name extension.edu is a top - level domain (TLD) reserved for educational institutions.
• For question 17: Green computing focuses on reducing the environmental impact of computing. Reducing overall energy costs is a key aspect as energy consumption in data centers and computing devices is a major concern.
• For question 18: UDP (User Datagram Protocol) is connectionless and has lower overhead compared to TCP. It is often used for real - time streaming applications where some data loss can be tolerated (unlike in file reassembly where TCP is more suitable for guaranteed delivery), and it is not inherently for encrypted communication or slow data transfer.

Answer:

1. An educational institution
2. Reducing overall energy costs
3. Real - time streaming
