Hi everyone!
We´re learning how to use HTML, it looks difficult, but it´s so easy.
First I´m going to put here the link that Elsa and I we had created:
file:///C:/Users/alumnobach/Desktop/Aisa.html
And now the HTML:
<!DOCTYPE html>
<html>
<head>
<title>Aida and Elsa's WEB</title>
</head>
<body>
<h2> Aida and Elsa's WEB :) </h2>
<p>This is <a href="http://ictaidarb.blogspot.com.es/">Aida's blog</a>.</p>
<p>And this is <a href="http://ictelsafreire.blogspot.com.es/">Elsa's blog</a>.</p>

Wifi security
Hi everyone!
Today I´m going to talk about Wifi
The wifi protocols and each speeds are:
- 802.11b → 11Mbps
- 802.11a → 54Mbps
- 802.11g → 54Mbps
- 802.11n → 300Mbps
- 802.11ac → 1300Mbps
Wifi SSID (Service Set Identifier)
- WEP is the most popular Wi-Fi security algorithm in the world, but is the less secure, it´s so popular because first it has more compatibility with machines, like 17 years ago.
- WPA is the system that sustitued WEP, the security is normal is not the final solution for the WEP problem.
- WPA 2 replaces WPA and it's the most secure, but it's not 100% secure. (remember that here in internet there is not something 100% secure)
Byee! ^_^

Cryptography
Hi everyone!
Today I´m going to talk about Confidentiality
Confidentiality is privacy.The data is only visible for the people who have rights.
We can get confidentiality with "cryptography", that consists is change your information so no one can understand it, except you and the ones who have permissions. In other words, encrypt the data. The opposite is decrypt.
To encrypt something you need an algorithm and a key. An algorithm is the patron you use to encrypt data, and the key is the number you use to do the algorithm.
In this page: http://www.cryptoclub.org/ you can encrypt and decrypt words or phrases.
And example, in the Caesar encryption, with the key 8.
