Answer:
Network Address Translation (NAT)
Explanation:
With the aid of Network address translation(NAT), the IP addresses of a particular local network are translated or mapped into a single or multiple global or public IP addresses. Therefore, a wireless router could use NAT to translate its private IP address on internal traffic (network) to a routable address for the internet.
With NAT, businesses can use many internal IP addresses since they are just for internal purposes and will be eventually converted into a single or a few multiple routable IP addresses.
Three types of NAT are possible:
(i) Static NAT : There is a one - to - one mapping between private IP addresses and routable (public) IP addresses. One private IP is mapped to one public IP address.
(ii) Dynamic NAT : There is a many- to - many mapping between private IP addresses and routable (public) IP addresses. Multiple private IPs are mapped to many public IP addresses.
(iii) Port Address Translation (PAT) : Many - to - one relationship between the private IP addresses and public addresses. Many private IP addresses can be mapped or translated into a single public IP address. This type of NAT is also called NAT overload.
Answer: The answer is d.
Explanation:
UDP is a transport protocol (Layer 4 of the OSI model) that has no mechanism to provide a reliable transport between the source process and the destination one, as TCP does.
Anyway, due to this feature, is specially suitable for real-time applications , like video or audio, provided that the user can accept some loss in the stream.
Several real-time protocols, like RTP for instance (used for videoconferencing) use UDP as transport protocol.

Answer:
E. Traditional leaders in communication have lost some control over information
Explanation:
Due to the quick development of new technologies like Internet, cable etc, traditional leaders in communication have lost some of their control over information. This means that the technological advancement is disruptive for traditional leaders. Following examples are given to elaborate the consequences of advancement in new technology in digital era.

Email technology has taken on some of the postal service's responsibilities and outperforms attempts to control communication outside national borders. This replaced the postal mail which used to take months to reach the destination.
The Internet and social media websites are transforming the way in which we access and interact with media culture. Before internet most people would watch popular TV shows in at the time they originally aired it. This scheduling gave common media interactions at specific times within our society. We still watch these TV shows but now we watch them at our own ease through websites. Using You tube we can upload our own media instead of viewing mainstream television.
