The week 4 lecture concerned the world wide web (www). This included understanding the difference between the net and the web. The web was described as an abstract virtual space that has a non-physical connection through hypertext links which can help to obtain documents, music etc.
Though the web cannot exist without the net, the net can exist without the web. This is because the connections in a network of computers is due to cables (physical connection) which allows the web to exist.
The history of the net is also discussed, focussing on the beggining of the net in 1965 where the first wide-area network was ever built in California. The when and why of the web are also explained.
When: Tim Berners-Lee (Researcher are CERN) in 1989
Why: To make the communication of information easier to send to one another
The 4 protocols for the www are also mentioned: TCP/IP, HTTP, DNS, URL
I also learnt about the different types of website eg: .org .com etc, which gives me an idea of the websites function and purpose.
A few slides of the lecture are dedicated to internet browsers: The types of functions it has and the differences between different browsers.
This lecture offers great information about the world wide web that most dont know. Searching for information on the net is much more efficient with this knowledge which can make future work much more efficient and of more value.
READING ACTIVITIES
A Brief History of the Internet
This page discusses various advancements of networks between computers and the creation of the internet. There is first discussion of the origion of the internet, explaining Leonard Kleinrock at MIT thought of the first packet switching theory which was the first step with the network between computers that could send information to and from. The page then continues on by explaining the concepts of internetting with packet switching with ARPANET which became the internet. The author also describes the introduction of TCP and IP as a communication protocol.Later through out the page the growth of the internet in the mid 70s is explained. A wide infrastructure was needed which invented the community which is existing today. Commercialisation also was a big point in history when there were buyers for this technology which led to network management to be more importantly maintained. The last paragraph explains the recent development of the internet which goes into much more specific details concerning the evolution that has occured and will occur including the advancements of broadand made and the investments needed to continue this growth.I found this page very interesting though there is a lot of technical jargon which makes it hard to follow though reading this has given me a general idea of how the internet became.
History of the World-wide Web
The website http://www.let.leidenuniv.nl/history/ivh/frame_theorie.html holds five chapters concerning the history of the internet. The first chapter explains the evolution of technology with communication becoming much more advanced as the time went by, allowing the reader to understand how the telegraph became a great head stone in the timeline and how computers evolved to produce benefits to society through out time, especially in world war 2.The second chapter describes the creation of the networking system "ARPANET", where protocols were also made to help recieve and send data to other networking machines 'computers'. There also an explanation of how the ARPANET became today's internet and without it there would be nothing compared to what we have today 'WWW'.The third chapter discussed the becoming of the electronic mail better known these days as email. Searching is discussed in the fourth chapter, with search engines being constructed to allow collecting information to become more efficient and easier. The fifth chapter contains various statistics about different countries usage of the internet and internet coverage in the year 2000 and as can be seen, there are not many who used it at that time which shows how much the internet can change in such little time.
TUTORIAL ACTIVITIES
http://www.martinlutherking.org/ ACTIVITY
Before visiting the site
My best guess is that http://www.martinlutherking.org/ will be an organisation about continuing with Martin Luther Kings mission to eradicate racism only because of the 'org' at the end of the url.
After visiting the site
I found the site to be of some quality, giving articles and reports concerning King's movements with references to support them. There isnt a large amount of biased content which allows for this website to be of reasonable quality. The information is also backed up by the civil rights library presented which holds information that uphold the accusations within the website. The site is also an organisation hence the ".org" which one can assume that this is an authentic site which can be relied on.
http://haggishunt.scotsman.com/ ACTIVITY (AUTHENTICATING)
Determining the authenticity of the 'Haggis Hunt' website was quite clearly not to be taken seriously. This site has flaws that can be recognised to know it should not be used for any professional assignment. Some of the flaws include the belief that haggis is actually some sort of animal repeatatively shown on every one of their pages when actually it is minced organs of a sheep.
There are also advertisement which are far from relative to the purpose and information on the website.
I also spotted a spelling error in their 'fact comment' which is a very unprofessional thing to do.
A scotsman.com search bar is up the top of the page which includes a link to a dating source which is unprofessional.
http://www.molossia.org/ ACTIVITY (AUTHENTICATING)
I knew the Molossia website was not to be taken seriously as a professional source by a few clues sighted...
Firstly the website holds a shop, which led me to ask myself what country has a shop on their national website?
As far as I know, there is no country in a state of USA and even with a little research my first beliefs were confirmed when no quality searches appeared concerning the Republic of Mollosia.
A quote by 'His Excellency, The President' shown in a thumbnail screenshot below shows how unprofessional and informal the language is presented.
A photo is presented with 'the president' aboard the M.S. Wombat. As you can see in the photo below, it is a photo to be taken lightly with laughter as the president is seen in what is meant to be a millitary vessel though a blow up boat.
