The Packets can be arrived out of an order from the Internet Protocol layer.
So, whenever the out of an order packets would be received then, it would be generated the duplicate ACK's, if we perform the re-transmission after the first duplicate ACK would be lead the senders to introduced too many redundant packets in the networks.
Explanation:
- All the bytes, in the Transmission Control Protocol connections, are the numbered, from the beginning at the randomly choose the initial sequence number (ISN).
- The SYN packets consumes the one sequence number, so the data will be actual and it begins at the ISN+1.
- The receivers ack's sequences the number x acknowledged the receipts of all the data bytes that is less than byte the number x.

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: Virtualization
Explanation: Virtualization is the term that describes about creation of something than its actual version. In computer field , virtualization can happen in the storage devices, server elements,network components , operating systems etc.
The mechanism of virtualization helps in a creating a framework in which the resources is divided into multiple units so that more execution and processing can be done in operating system environment. So, the data center has used the virtualization trend for the separate web servers
