Class 9: My Favorite 3 Prezi presentations

These are the screenshots of my favorite 3 presentations that I found as I explored through Prezi
What I have noticed was that most of the Prezi presentations were very business oriented, in which I find very useful and helpful. There were many categories of presentations about marketing, case studies, presentations, company pitches, and much more.

Class 9: Hypertext Markup Language (HTML)

HTML also known as hypertext markup language is used to communicate among various computers with each other. In older version, it was originally called SGML, Standard Generalized Markup Language. However, the HTML has a fundamental capability, in which is its’ ability to make hyperlink. This is essentially what makes the web and webs can be viewed by anyone sharing the network or connected to the Internet. Without it, we would not have able to communicate through web.

There are several versions of HTML, in which all of the modern browsers can support all. There are Quirks mode, HTML 2.0, HTML 3.0, HTML 4.01, and HTML5. HTML 5 is in the working progress, supported by WHATWG and W3C. HTML is in a form of codes written in a text-file, in which the text is saved as html file, and finally can be viewed through a browser.

While the WHATWG is used in major browser implementations by big companies like Apple’s Safari, Google’s Chrome, and Mozilla’s Firefox,  HTML5 is the HTML Working Group of the W3C . Although it looks fairly easy to learn, it later can get very complex in creating a logical code in order for the computers or mobiles to read the command.

Reflecting on Tonight's Class

I really enjoyed tonight's class especially using Minecraft. It was my first time actually working with group members to create a ship as well as a building at the Colorado server.

Here is some screenshots of the building that we worked on.

Class 8, The Bitcoin Blockchain

Bitcoin is a digital wallet/currency used as an online payment system. Thus, it can be used without usage of a credit card or the bank. The users can transfer money by peer-to-peer system (P2P) in a very efficient and easy way. It was invented by Satoshi Nakamoto in 2008 and was released as an open source a year later, 2009.

It also runs both on your computer or mobile phone, generating your Bitcoin addresses. You can disclose your address anytime you want to make a transaction with other person. Moreover, one of the interesting facts is that no one runs Bitcoin; Bitcoin runs collectively by the users and all of the Bitcoin users are managers. Bitcoin has this function called ‘blockchain’, in which records and works as a public ledger of all transactions in the Bitcoin network.

In another words, it is a shared public ledger that includes all transaction in records. While confirming waiting transactions, the block chain includes mining process, a distributed consensus system, to confirm and makes a chronological order in the block chain, enforced with cryptography.

Class 8, Peer to Peer (P2P) & BitTorrent

It is hard to distinguish and find the difference between a P2P and a Bit Torrent, since they are very similar and have subtle differences – they are used to download and share files collectively, using many computers sharing the same network.

Bit Torrents uses as many computers as possible within the shared network and receive any file in an appropriate format – it can breaks the files into smaller pieces, and can be uploaded to use by another person. It shares the loads of files from many computers or different people at the same time. One difference is that it is much faster in transferring large files than a P2P network.

On the other hand, P2P is transferring files directly between the two distinguishing computer users – host 2 host transfer. Pro is that the user can identify where the files come from, and the downside is that the speed is limited to the speed of sending file data.

Thus, P2P is good when downloading small files like mp3, video clips, etc and Bit Torrents are good for dealing with the larger files and data.

It is a brief and easy introduction about what P2P is and how it works
