CYBERBULLYING

Do you use the Internet in a responsable way? 

Do you know everyone you talk through the social reds? 

Do you use social reds in a save way?

Maybe you aren´t sure of what you are answering to this questions, this it is very difficult to use the Internet in a completely save way, but maybe I can help you to use it better. 

First lets see what is cyberbullying. 
Serching in the Internet I found this web side about cyberbullying and bullying:

https://www.stopbullying.gov/cyberbullying/what-is-it/

And this is another vídeo that I found in http://www.pantallasamigas.net/

If you want you can go inside it and learn a little bit more about it.

Cyberbullying is bullying but that take place using technology like social reds like gmail, WhattsApp, Twiter, Facebook, etc.
The best thing you can do once it happens is to tell it to someone that can help you, preferently an adult. I know that is a thing that is not so easy to say, but you have to find the way to comunicate it to someone before the situation gets worst. 
It can also happens to another person and if that happens you have to try to help him.

I hope you´ve learned a lo about cyberbullying. 
See you!

INTERNET

-What is the internet?
·The Internet is a network of thousands of computers and devices around the world connected by copper wires, fibre optics, wiereless connections and other methods.
-The Internet of Things:
·It is a revolutionary concept that describes the connection of everyday objects to the Internet so that we can interact with them.

·For example:

Imagine that you have gone to the cinema and you have forgotten to raise down your bedroom´s blinders, you just have to take your movile phone and as fast as you sent a message you can raise down your blinders.

-Internet basics:

·We can access information on the Internet with the help of two basic elements:
-The browser.
-The search engine.

·A browser is a programe that displays the content of web pages.

·For example:

Internet explorer, Google Chrome, Mozilla Firefox, Safari, Opera, etc.

·A search engine is a computer that indexes files stored on websites. Search engine keep their results up to date by continually crawling the Internet.

-How the Internet works?:

1. Users can connect to the Internet if they have a contract with an Internet service provider (ISP) and pay a set fee. When we switch on a computer and conect to the Internet, our ISP assigns an address to our computer, called an IP adress. Every computer is assigned a unique address on the Internet.

·Example of ISP: 

Movistar, Jazztel, Ono, etc.

2. A router is a divice that lets us connect to the Internet. Once connected, we open our browser and type the address of a page in it (URL). At this point, information starts to travel in the form of packets. The information sent out of the request or address of the web page that we want to visit and the information that is sent back is the content of the web page.
Each web is also assigned an IP. This way, we can identify the origin and destination of the flow of information.

3. The next step in the information´s journey are the DNS. It would be very difficult to remember the IP address of every website that could connect with. DNS servers simplify this task for us. DNS stands for domain name system and these servers assing a name to each IP address in the same way that a telephone directory assings names to telephone numbers so that we don´t have to remember all. 

·For example:

If we type the IP 64.233.189.104 in your browser, we are connected t the Google home page, which is the same as typing in ''https://www.google.es''. 

4. Our computer cominicates with other computers following a common set of rules called a protocol.

·The packets of information follow the TCP/IP protocol (transfer control protocol/Internet protocol).

·Servers use the HTTP protocol (hypertext transfer protocol) to send and recive documents over the Internet.

5. The DNS server sends the request to the server that hosts the web page we want to visit. The server sends us the information packets that make up the web page, which travel over the network along the quickest path that they can find.

6. Finally, the packets reach our computer and are reassembled. The page is then displayed in our browser.
