Week 4

This week’s lecture reflected upon Old Communication Technologies, with the lecture starting off with a look at an old rock scribing featuring animals in different positions with several humans scattered over the piece. Whereas the meaning of the work was unclear, it was still interesting to note the way humans communicated in that age.
Also discussed was the origins of the alphabet, ancient texts and jumping forward many years, print, telegraph, telephone, radio, cinema etc.
The subject of semiotics was also brought up, which seemed interesting, followed by the perspectives of several notable theorists.

During the tutorial this week, a scavenger hunt was conducted with the answers as follows; (Some were not found)

Also in the tutorial, the question was asked as to how search engines rank the stuff they find on the internet. I found this brief description on http://www.buzzle.com/editorials/6-10-2005-71368.asp

“It's common knowledge that Google relies heavily
on inbound relevant links to rank a site. Now they explain exactly how it works.
As well as the number, quality and anchor text factors of a link. Google
seems to also consider historical factors. Apparently the Google 'sandbox' or
aging delay begins count down the minute links to a new site are discovered.
Google records the discovery of a link, link changes over time, the speed at
which a site gains links and the link life span."

Another useful site I found entitled “Search Engine Ranking Factors” which was put together by 37 leaders in the world of organic search engine optimization and included 200+ ranking factors. Although too long to be summarised in this blog, it is of much value and is recommended for reading. The site is:http://www.seomoz.org/article/search-ranking-factors

When asked what our favourite search engine is, I decided have found Google to be my favourite search engine, for the simple fact that it provides a vast array of information closely related to the searched subject matter.
