(Back to Fall2003 Midterm Review 2)

a) A Domain Name Server resolves an internet address in DNS format, such as www.cnn.com into an IP address, which is the four number system like 11.222.3.44 and is the exact address of the specific computer on the Net.
b) FTP stands for File Transer Protocol, and is a standard protocol for transfering files across the Net. Imagine that... SMTP is Standard Mail Transfer Protocol, and is a protocol for sending email. HTTP is HyperText Transfer Protocol, and is used for webpages. Each protocol is capable of understanding a set of commands used in each each of expertise, for example FTP recognizes when to begin a transfer, checking to make sure everything gets across, and then when to end the transfer.

Good job explaining - Jack DeBussey

c) HyperText is the language of webpages. It's a language that includes not only information, such as this answer, but also formatting instructions, such as font size, font type, locations of pictures within a page and where to download them from. It's also considered non-linear text in that hypertext documes allow you to follow a thread of a topic through multiple pages, and then return to where you were.

Also a good job - Jack DeBussey

d) A client is the program you run to access a particular set of protocols, though I'm not saying this well. Internet Explorer is a client used to browse the web. CuteFTP is an FTP client. A server is a computer that has information, data, whatever that you access by the client, for example the server at cnn.com that has all the news stories.
e) Since webpages are constructed in text and the way we see them is just an encoding, we can write programs that read multiple webpages quickly in looking for information, simply by reading the text that they're made of. For example a program to get weather reports for a city input by the user will scan the source code of the webpage for the weather information.
f) The Internet is a gigantic network of smaller networks.
Jeff Baker

a)DNS: A general-purpose distributed, replicated, data query service chiefly used on Internet for translating hostnames into Internet addresses.
b)FTP: file transfer protocol. A communications protocol governing the transfer of files from one computer to another over a network. SMTP: simple mail transfer protocol. Sends mail to people. HTML: hypertext markup language. A markup language used to structure text and multimedia documents and to set up hypertext links between documents, used extensively on the World Wide Web.
c)A computer-based text retrieval system that enables a user to access particular locations in webpages or other electronic documents by clicking on links within specific webpages or documents.
d)Client: A computer or program that can download files for manipulation, run applications, or request application-based services from a file server. Server: A computer that processes requests for HTML and other documents that are components of webpages or a file server.
e)It is easier to find information that you want to find with programs. These programs scan the pages to find the information instead of going through the encoding manually.
f)An interconnected system of networks that connects computers around the world via the TCP/IP protocol

Hypertext isn't really a language. It's simply non-linear text. Ever use Microsoft Help where you click on terms to get to other entries? That's also Hypertext, but it's not on the Web. Rest looks good! Mark Guzdial

So what does non-linear text really mean?

That you don't read just down the page. You read a little, click, go somewhere else, click, read some more. The total opposite of a papyrus scroll! Mark Guzdial

Wooooo~ nice! Non-linear text rules!
