TUTORIAL ACTIVITY ONE:

Four Tips To Help You Search On Search Engines:

1.Search Plan:

Have a stratagy before you go on the web. Do not just conduct a broad search so you get various URLs have key words and phrases in mind so the search is quick and efficient. For example if your searching on a topic such as childhood obesity don't just write in obesity because the search will be too braud. Type in childhood obesity.

2. Directories:

Use a web search directory to help you locate a wide range of information on one single topic rather than typing in several words and then siving through all the waffle to find information.

3.Search using Meta Tags:

Search engines are now using meta tags this is like html at the front of the site. The use of meta tags means that the writer of the site can influence what it is you search and how much information you are allowed access to for your search.

4.Searching Using Phrases:

Some websites see it as necessary to use inverted commas when you are using phrases, this helps to make the search more efficient. For example if you are searching on a topic such as babies and sleep patterns you need to put into inverted commas "nappies" so the computer knows exactly what you are searching for.

SUMMARY:

This first activity has explained how to search search engines properly and what to look for.

ROBERT HARRIS WEB SEARCH STRATAGIES:

Information on the web:
e in the most simple form three catagories of information on the web.
.Free visible web-This is all the general web pages such as google and yahoo

.The free invisible webThis is information that is also provided without charge but can only be accessable by going directly to the site where the information is contained.

.The payed web-Commercial sites that libraries subscribe to to access their online journals.

Search tool types:
Like databases search tools also occupy three main catagories.

Search engine:
A search engine consists of the main face that you use to type in a search query. The query is then paired up with a spider program called a bot. The bot goes through the internet getting new sites for the search engine. An example of a search engine is google and yahoo.

Directories:
Catagorised lists of sites that are searched and then eventually selected by editors. This means that the quality of information on these sites is of a higher educational quality as people actually hand pick them.

SUMMARY:

The first reading has explained different search tool types and how to use them.


READING TWO SUMMARY (URL) THE HISTORY OF THE INTERNET (Chapter 4 Search Engines) :

Chapter 4: Search Engines:

This reading looks in detail at what information is contained on the web and how to locate the information you want.

Origins of search engines:
The first search engine began at the Mcgill university in montreal in 1990 and was given the nickname Archie. Prior to the initiation of Archie the way people accessed files was through a painstakingly long process but now with archie people could simply open files and send them to themselves and then browse the files at their leisure. With it's quick information access archie soon became very popular and was the open window for other such sites. Some other such systems inotiated after archie include:
-1991 The gropher system
-WAIS(Wide area information server)

These two systems then made way in 1991 for the WWW and the MOSAIC sites. These two new inventions not only broadened the span of computers and the amount of information they could hold but it also made them user friendly.
It is now very easy to find search engines on the internet just by typing in a single word or one phrase. The internet has come a long way since the invention of Archie in 1990 and now contains a number of high tech functions.

SUMMARY:

The second reading has explained the history of the internet.
