Unit 28, Task 1, M1 and D1

M1

Web 2.0 - Web 2.0 is the second generation of the World Wide Web which allows people to collaborate and share information. Web 2.0 refers to a more dynamic web that is based on serving web applicators to users. Web 2.0 also has other improved functions for example, open communication with emphasis on web based communities. I have used Web 2.0 when using social media sites. Uploading pictures to Facebook or Twitter and editing a Wikipedia page are examples of using Web 2.0.

Blogs - Blogs are web pages that are set up by authors. It is almost like an online journal where writers can share their ideas and opinions. They can either be set to public or private which determines who is able to read the blog. They are usually filled with thoughts and ideas of the author. I use the website Blogger to upload my school work to. My classmates and teachers can access my work however I have complete control over who views my work as it can be kept private.

Online Application - This is a program made using a browser supported language that relies on the browser to use the application. Examples of online applications are calendars and calculators. I have used Google Calendar to keep track of my school work.

Cloud Computing - Instead of storing data on your computer's hard drive you are able to store and access it online using iCloud and Google Drive. This easily allows you to access documents that you have created online. This makes it much easier to access documents as you can sign into your account on any computer and have immediate access to the data. I use Google Drive to create all my documents with school work on. This makes it easier as the work can be easily accessed at home and on other computers.

D1

TCP/IP - The first layer of the transmission control protocol handles data that gets sent to other computers. When you buy a computer that has the internet already installed the TCP/IP will already be installed. The role of the TCP is to compact all the data. The main packets will be sent to the second layer of the protocol which is used to obtain the web page address that the data is being sent to. The protocol is adds the address to the packet. Before the packet is moved, this section is always read and handled with first. If the internet connection is bad or slow the packets are assembled slower. For example, the text or images may appear before anything else. Also, if there is a large image it can sometimes take a while for it to load. 

HTTP - This stands for Hyper Text Transfer Protocol which is used to distribute hypertext across the internet. HTTP makes the web pages actually work. This is what lets you access different parts of a website. For example, if you are on a clothes website it allows you to click on the different pages.

HTTPS - This stands for Hyper Text Transfer Protocol Secure and basically does the same as HTTP but is much more secure and is used for online banking and other services that require more security. I have experience with HTTPS when using online banking. It is vital that personal details are kept secure.

SMTP - This stands for Simple Mail Transfer Protocol and is used for electronic mail transmission. This enables users to send electronic mail between two devices e.g Gmail. I use SMTP when I exchange emails with my teachers to get feedback on my work.
