My learning points from the 57 slides

Wow, I have learnt so much from this assignment and have read much about the internet and its history. Some things I did not even know they existed, like ARPANET and what it is, and I had no idea what html was for. Let me list 10 of my learning points.

1) I had always thought that the internet had originated from the 1990s and that it was actually pretty new but actually, it originated in September 1969, as the ARPANET, which was a networking project. It stands for Advanced Research Projects Agency (ARPA) and the NET, well, stands for net (connection). This allows scientists at different locations to share information, so it was the birth of the internet. I had never known this before so it is something new to me.

2) I never knew what ".com" was called in the technical way and now I know it is a domain. The domain is a text version of the IP (internet protocol) address and the IP address is the number that uniquely identifies each computer or device that is connected to the internet.

3) What is the World Wide Web? I know that "www" stands for the World Wide Web from a movie called "Transformers" but never really understood what it was for. Now I know that it is a world wide collection of electronic documents. I know what a website is, so the Web (WWW) is a compilation of most of the websites. If there was no triple w, all our electronic documents would be scattered and we would not have a universal way of viewing them, and everything would get extremely complicated. This has thus answered my question.

4) I now know what URL stands for. Uniform Resource Locator. It is a unique address that every single webpage has and when people type the URL of a webpage into a web browser, it would load that web page.

5) I did not even know what a subject directory is so after I read the 57 slides, I learnt that it is a search tool with an organised set of topics and subtopics. It is easier in a way that it allows people to search information, by clicking on links, but it does not allow the person the freedom of searching what is not in the subject directory.

6) I have learnt the 9 different basic types of websites, which include the portal, news, informational, business/marketing, educational, entertainment, advocacy, blog and personal. All of these different types of websites have different domains, and they all serve their purposes, which is obvious in their names. For example, advocacy contains content that approves and promotes a certain idea or action.

7) I have learnt the different image formats that are used for the web pages. There are many which include BMP, JPEG, TIFF, GIF and PNG. I have actually realised that when my father uploads the images from his camera onto the computer, they are usually in the JPEG format. However, some of my images from my phone have a PNG format. From research, I have found out that the difference between JPEG and PNG are that JPEG actually compresses the image but makes the image of lower quality saving space. However, PNG is a lossless sort of format that, unlike GIF, has many more different colours and thus it looks nicer.

8) (Actually I have already posted this learning point in one of my earlier posts, about the thumbnails.)

9) I have found out that transactions made over the internet (usually business) are called e-commerce. I have bought some goods over the internet and found out how efficient it is and how fast it actually is. 

10) (Last but not least!) I thought before that email came quite late after the internet was created because of Gmail, which came out in around 2007. I have always used Gmail so I was quite confused when the Powerpoint mentioned that emailing was one of the original services on the internet, so emailing is actually pretty old, but I do not know how people sent emails then, with no email addresses. It is actually an extreme convenience to have emailing, as we can send people messages and they would receive it almost instantly. However, now with technology becoming better, what would come after email?
