Lecture (Week 5)

Todays lecture was about using search engines.
Some search engines include-
Google
Yahoo
Ask Jeeves
City Search

Some problems you could face when using search engines are:

Not finding the information relating to your topic-
Determing how deep to tunnel through lower ranked pages
Building enormous indices
Misuse of page scoring, ranking

To avoid this you could basically try and use better key words
Guess a location
Use several search tools
Read search tips
Back up, select what you want
Use advanced search function

There are 3 categories of information on the web.

The free visible web
The free invisible web
Paid Data Bases over the web


Search Tools fall into two main categories.
Search Engines
Directories

A search engine is a web based application program that crawls the internet, creating indices of websites usually from the textual information.

Directories
Human Edited
Web pages are submitted to directories and then reviewed


The most reliable search engines are:

Google
Looksmart
Yahoo
About
DMOZ

Lecture (Week 4) + Tutorial Activity

The World Wide Web

An example of a browser interaface



The 'www' is an abstract space of virtual information. It was developed by Tim Berners Lee in 1989 to facilitate the sharing of information.



Web browsers include:

Mozilla

Int. Explorer

Neoplanet



Tutorial Activity


This is the Haggis Hunt Website: The Republic of Molossia Website:


www.haggishunt.scotsman.org

This website didn't look genuine because it contained a fake animal called 'haggis' when in actual fact haggis is the lining of a sheep's stomach.
The site was full of games, videos etc. and had partnership with dating websites etc.
This showed me that the site wasn't really there for a purpose other then to make money from advertising.

The Molossia website was obviously a spoof aswell, theres no such place as Molossia so therefore its obviously not a genuine website.

10 Useful Functions and Search Tips from ECU Library Site

- Entering a few key terms you have identified to describe your topic will enable you to quickly search many of the subject indexes and retrieve a few references

- Some indexes allow you to search on the individual terms and get a result and then combine the sets using the operators

- Some databases use truncation to pick up variations of the terms used.
An * or ? is substituted for letters to broaden the search

- When the results of your search are on the screen, the next task is to read
through them and select those which seem to most support the argument you
wish to write about in your assignment. These results can be marked up for
printing or in a lot of cases the databases accessible on the web, allow you to
email them.

- Your results will generally be in the form of a list of citations and abstracts or
just citations and in some cases, full text journal articles. If you have a list of
citations or citations and abstracts without the full text, the next step is to check
the Edith Cowan Library catalogue to see if they are held on the library
shelves.

- Useful options to look out for :

Buttons or icons to return you to the results or marked list

Arrows which direct you to the next step

An option which allows you to modify keyword searches, by combining
searches with the operators AND or OR.

The list of graphics used in a full text database to describe the various
reference types: citation, full text, full text and graphic, full text image


-Most databases are web-based and can be accessed using the terminals in the library or elsewhere on campus, however, a number of these databases are also available for you to use at home. Choose one of the access options and follow the instructions on Off-campus access. Some databases are only available in the library.

-To access databases in the library you will need a megalab (computer) login and password. These can be set up using the SIMO online enrolment system

-Journals may also be available electronically through the Web and are referred to as ejournals or electronic journals.

-The library has a large collection of ejournals which can be accessed by doing a journal title search in the library catalogue or by searching in a full text database by keyword or journal title

Lecture (Week 3)

Todays lecture was about online libraries and databases. The lecturer covered the reasons why we should use online databases, some of these reasons were:
-convenience, internet connection
-currency, journals are up to date
-electronic format, easy to make notes etc.
-anywhere/anytime access

Reasons against it are:
-Hidden content
-Most do not access database and library indexes

There are many different types of libraries:
-online text repositories
-online journals
-electronic books
-musical
-artworks


Some online resources include www.virtuallibrary.com

Limitations of Online Libraries:
- Only the catalogue is online. However you can still browse through and search through the collections.
-Many libraries are available only by subscription, therefore it may require a fee.
-Resolution may be reduced as you are seeing copies of original works eg. art, music
-They are often updated on a regularly basis and can be out of date.

How Pc's work
*Computers have changed our way of life and will continue doing so in the future.
*A PC is a general purpose tool built around a microprocessor
*Has different parts that work together
*You can use it to type documents, send e-mail, browse the Internet and play games.
*Central processing unit (CPU) - The microprocessor "brain" of the computer system is called the central processing unit. Everything that a computer does is overseen by the CPU.
*Memory - This is very fast storage used to hold data. It has to be fast because it connects directly to the microprocessor. There are several specific types of memory in a computer:
*Random-access memory (RAM) - Used to temporarily store information that the computer is currently working with.
*Read-only memory (ROM) - A permanent type of memory storage used by the computer for important data that does not change.
*Basic input/output system (BIOS) - A type of ROM that is used by the computer to establish basic communication when the computer is first turned on. *Caching - The storing of frequently used data in extremely fast RAM that connects directly to the CPU.
*Virtual memory - Space on a hard disk used to temporarily store data and swap it in and out of RAM as needed. Motherboard - This is the main circuit board that all of the other internal components connect to.
*Power supply - An electrical transformer regulates the electricity used by the computer. *Hard disk - This is large-capacity permanent storage used to hold information such as programs and documents.
*Operating system - This is the basic software that allows the user to interface with the computer. *Integrated Drive Electronics (IDE) Controller - This is the primary interface for the hard drive, CD-ROM and floppy disk drive.
*Peripheral Component Interconnect (PCI) Bus - The most common way to connect additional components to the computer, PCI uses a series of slots on the motherboard that PCI cards plug into.
*SCSI - Pronounced "scuzzy," the small computer system interface is a method of adding additional devices, such as hard drives or scanners, to the computer.
*AGP - Accelerated Graphics Port is a very high-speed connection used by the graphics card to interface with the computer.
*Sound card - This is used by the computer to record and play audio by converting analog sound into digital information and back again.
*Graphics card - This translates image data from the computer into a format that can be displayed by the monitor.
