INTERNET QUESTIONS

This is an excerpt from the paper...

1. Although it appears that information on the Internet is transferred in the same manner as it eventually is displayed·such as an entire document·it actually is broken into smaller data sets called packets. Each packet is preceded by the internet protocol (IP) address and is also assigned a sequence number. Packets are sent from the source to the destination computer, but may get routed along a different path. The IP addresses and sequence numbers ensure that the packets are properly reassembled at the other end. The result is an apparently seamless transfer of information that occurs within a few milliseconds and is transparent to the user.

2. The International Standards Organization (ISO) developed the seven-layer Open Systems Interconnection (OSI) data communications model in the early 1970s. It has since become the model used for most major data communications standards. The model breaks up information into seven stacked layers, the top of which is the most sophisticated applications layer and the bottom-most of which is the physical layer. Transmission Control Protocol/Internet Protocol (TCP/IP) is the way that users are able to communicate across different hardware platforms on various networks. As its name implies, TCP/IP is the requisite protocol for sending and receiving messages on the Internet. TCP/IP typically resides in the transport layer of the OSI model.

speeded up, interfaces can be enhanced, and network throughput may be lessened since the client can now take over some or much of the processing. 6. Blogs might be used by a company to put out favorable comments about its own products, or unfavorable comments about a competitor's product, although the second option could be problematic if the information is untrue. Thus blogs can be a marketing tool. Another use of blogs would be to try to shape public opinion about an issue that affects the company's operations. Thus a pharmaceutical company might encourage employees to blog about pending legislation that would limit the public's ability to sue drug companies. A blog is an online journal maintained by an individual that is updated on a regular basis·often several times a day·and that is typically associated with "stream of consciousness" writing, although this is not always the case. Where a blog is typically text-based without much formatting, a wiki is software that resides on a server which allows for simple Web editing so that content can be formatted and arranged for Web display in nearly any Web browser. New pages and links within internal pages can be created quickly and easily with a wiki; blogs typically·but not
