The World Wide Web grew publicly obtainable in 1991. The Internet developed speedily, and by 1996, it was portion of mass growing. By 1999 virtually every nation had a connection, and approximately half of Americans and personalities in various other countries practiced the Internet regularly.
Yet completely the 1990s, "getting online" necessitated complex configuration, and dial-up was the only connection variety affordable by unique users; the contemporary day mass Internet culture was not possible. The initial Wiki was introduced with WikiWikiWeb on 1999.
Answer:particular layer N, a PDU is a complete message that implements the protocol at that layer. However, when this “layer N PDU” is passed down to layer N-1, it becomes the data that the layer N-1 protocol is supposed to service. Thus, the layer N protocol data unit (PDU) is called the layer N-1 service data unit (SDU). The job of layer N-1 is to transport this SDU, which it does in turn by placing the layer N SDU into its own PDU format, preceding the SDU with its own headers and appending footers as necessary. This process is called data encapsulation, because the entire contents of the higher-layer message are encapsulated as the data payload of the message at the lower layer.
What does layer N-1 do with its PDU? It of course passes it down to the next lower layer, where it is treated as a layer N-2 SDU. Layer N-2 creates a layer N-2 PDU containing the layer N-1 SDU and layer N-2’s headers and footers. And the so the process continues, all the way down to the physical layer. In the theoretical model, what you end up with is a message at layer 1 that consists of application-layer data that is encapsulated with headers and/or footers from each of layers 7 through
Explanation:
Answer:
a. Establish a theory of probable cause.
Explanation:
Heather now knows the cause, and She is quite experienced. She is now studying the cause, and she is trying to come up with the theory of probable cause now. And as she will be able to come up with the theory, the practical will follow, and she will be able to remove the fault then. And hence the correct option is as mentioned in the answer section.
