TEFL CLASS March 24th, 2014

1. Please list THREE search engines your group members use more frequently. Compare the three search engines and choose your favorite one and explain why this one is the best.
Google, Yahoo, and MSN.
Google : Google possesses one of the most globally recognized brands in the world, and brand loyalty is strong
Yahoo : A large, unique search engine database
MSN : MSN is more spesific than another search engine
For us, the best search engine is google. Why? it's because Google is more popular and easy to access and with one click we can find so many reference.
2. What difference does it make when you enter keywords or phrases in quotes (e.g., "computer assisted language learning") in your web search?
Google doesn't use such a keyword in quotes, so we think it doesn't work if we use such a thing in google engine.
3. If you put the word "OR" between words/phrases in your web search, what does it mean?
Google usually show more reference through the content. 4. You can also use these signs " + ", " - ", and " ~ " in your web search. What function does each sign have? Please give examples. (Be sure to include a space before a sign, but no space after a sign. e.g., movie -video)
If we use (+) before the word, the search engine will show a specific content about the keywords, if we use (~) then the search engine will show a reference that related to the keywords, if we use (-) it'll not show anything.
5. There are different domain types in websites' URLs. What do these domain types mean? .com .edu .gov .org .net .mil
.com = Computer output on microfilm or microfiche
.edu = Top level domain for education
.gov = Top level domain for governments
.org = Top level domain for non-profit organizations
.net = for network infrastructure
.mil = Top level domain for the military
6. If you want to find images or sound files on the Web, what should you do?
We'll put a keywords such as .mp3 or .mp4 after the first keyword (usually it's the title) and if we want to search for images, then we'll click 'google images' and put the keywords there.
7. In addition to providing easy access to billions of web pages, many search engines also provide a number of special features to help people find what they want more efficiently. Please find what special features those search engines have and choose THREE features that you like the most each engine offers.
Google special features = Google images, google scholar, and google map
Yahoo = yahoomail, yahoo messenger and yahoo answer
MSN = bing, outlook and skype
8. What web search problems have you encountered before? Please share some with your group members and see if you can find solutions now. Each group needs to report at least two common problems and your solutions (if you have found them).
- the website doesn't exist anymore and we found a warning such as '404 not found'
- sometimes our country can't access some website, so it won't show up
Solution : We will look up to another reference.

Search Engines

What Is the Function of Search Engines?
- Search engines help in searching and matching of documents in the system. Searching the inverted file for documents that meet the query requirements, referred to simply as matching, is typically a standard binary search, no matter whether the search ends after the first two, five, or all seven steps of query processing.
- Search engines are necessary for locating, sorting, storing and ranking the value of that information on the web. Popular search engines like Google, Yahoo and Bing find relevant information and present it to users. In order to efficiently find a specific bit of data, it’s important for you to know the four main functions of the search engines.

TEFL CLASS (March 17th, 2014)

- Browser : A browser is a program used to browse the web. Some common browsers include Netscape, MSIE (Microsoft Internet Explorer), Safari, Lynx, Mosaic, Amaya, Arena, Chimera, Opera, Cyberdog, HotJava, etc.
- Frame : Frames' are pages that are displayed within an HTML page. Frames behave like a separate window with their own menus, scroll bars, and content. Frames let you keep your logo and menu for example fixed on the screen while simultaneously displaying another page, even somebody else's website, inside your web site.
- Server : A file or value of an environmental variable, that is included in an HTML document, so that information such as last date modified, file size, author etc. can be automatically included.
- Plug-in : A plug-in is a piece of software designed not to run on its own but rather work in cooperation with a separate application to increase that application's abilities.
- Applet : A small Java program that can be embedded in an HTML page. Applets differ from full-fledged Java applications in that they are not allowed to access certain resources on the local computer, such as files and serial devices (modems, printers, etc.), and are prohibited from communicating with most other computers across a network. The common rule is that an applet can only make an Internet connection to the computer from which the applet was sent.
- Cookie : A cookie is a small file that a web page on another machine writes to your personal machine's disk to store various bits of information. Many people strongly detest cookies and the whole idea of them, and most browsers allow the reception of cookies to be disabled or at least selectively disabled, but it should be noted that both Netscape and MSIE have silent cookie reception enabled by default. Sites that maintain shopping carts or remember a reader's last position have legitimate uses for cookies. Sites without such functionality that still spew cookies with distant (or worse, non-existent) expiration dates should perhaps be treated with a little caution.
- Telnet : The command and program used to login from one Internet siteto another. The telnet command/program gets you to the login: prompt of another host.
- Netiquette : The established conventions of online politeness are called netiquette. Some conventions vary from site to site or online medium to online medium; others are pretty standard everywhere. Newbies are often unfamiliar with the conventional rules of netiquette and sometimes embarrass themselves accordingly. Be sure not to send that incredibly important e-mail message before reading about netiquette.
- Navigation button : either text links or GIF graphics which the reader can click to move around in your publication. WordToWeb can automatically insert navigation buttons into your HTML pages.
- Hypertext : Generally, any text that contains links to other documents - words or phrases in the document that can be chosen by a reader and which cause another document to be retrieved and displayed.
- Pull-down menu : In computing and telecommunications, a menu is a list of options or commands presented to an operator by a computer or communications system.
- Pop-up window : Pop-up ads or pop-ups are often forms of online advertising on the World Wide Web intended to attract web traffic or capture email addresses.
- Scroll : a roll of parchment or paper for writing or painting on. If it's verb : move displayed text or graphics in a particular direction on a computer screen in order to view different parts of them.
- Search engine : Search engines are the websites that send out spiders to collect data from the internet so that sites, information and content can be found easily using a search query. Examples of such search engines are Alta Vista, Excite, Google and MSN Search. There are many search engines on the internet.
- Domain name : the part of a network address that identifies it as belonging to a particular domain.
- Spam : irrelevant or inappropriate messages sent on the Internet to a large number of recipients.
- WWW : Long for WWW, a system of Internet servers that support specially formatted documents. The documents are formatted in a script called HTML (HyperText Markup Language) that supports links to other documents, as well as graphics, audio, and video files. This means you can jump from one document to another simply by clicking on hot spots. Not all Internet servers are part of the World Wide Web.
- HTML : Hypertext Markup Language, a standardized system for tagging text files to achieve font, color, graphic, and hyperlink effects on World Wide Web pages.
- HTTP : The hypertext transfer protocol is the native protocol of browsers and is most typically used to transfer HTML formatted files. The secure version is called "https".
- URL : A uniform resource locator is basically just an address for a file that can be given to a browser. It starts with a protocol type (such as http, ftp, or gopher) and is followed by a colon, machine name, and file name in UNIX style. Optionally an octothorpe character "#" and and arguments will follow the file name; this can be used to further define position within a page and perform a few other tricks. Similar to but less general than a URI. The exact distinction is beyond the scope of this document.
- FTP : A very common method of moving files between two Internet sites. FTP is a way to login to another Internet site for the purposes of retrieving and/or sending files. There are many Internet sites that have established publicly accessible repositories of material that can be obtained using FTP, by logging in using the account name "anonymous", thus these sites are called "anonymous ftp servers". FTP was invented and in wide use long before the advent of the World Wide Web and originally was always used from a text-only interface.
- ISP : An Internet service provider is a company that provides Internet support for other entities. AOL (America Online) is a well-known ISP.
- TCP / IP : (Transmission Control Protocol/Internet Protocol) This is the suiteof protocols that defines the Internet. Originally designed for the UNIX operating system, TCP/IP software is now included with every major kind of computer operating system. To be truly on the Internet, your computer must have TCP/IP software.
- BBS : A bulletin board system is a computer that can be directly connected to via modem and provides various services like e-mail, chatting, newsgroups, and file downloading. BBSs have waned in popularity as more and more people are instead connecting to the Internet, but they are still used for product support and local area access. Most current BBSs provide some sort of gateway connection to the Internet.
- LAN : A computer network limited to the immediate area, usually the same building or floor of a building.
- WAN : Any internet or network that covers an area larger than a single building or campus.
- PDF : a file format that provides an electronic image of text or text and graphics that looks like a printed document and can be viewed, printed, and electronically transmitted.
- GIF : GIF images are some of the only forms of pictures that can be used on the internet, and the only ones that can be animated for use in banners, etc.
- JPEG : Joint Photographic Experts Group, or JPEG is most commonly mentioned as a format for image files. JPEG format is preferred to the GIF format for photographic images as opposed to line art or simple logo art.
- MIDI : short for midiskirt, a skirt that ends at the middle of the calf.
- CGI : A set of rules that describe how a Web Server communicates with another piece of software on the same machine, and how the other piece of software (the ?CGI program?) talks to the web server. Any piece of software can be a CGI program if it handles input and output according to the CGI standard.
- IRC : Internet relay chat is a means of chatting over the Internet in real-time. It allows both open group discussions and private conversations. IRC programs are provided by many different companies and will work on many different platforms. AOL's Instant Messenger utilizes a separate incompatible protocol but is otherwise very similar.
