Internet Security

Hello again, I share a new post with you today to explain a bit about security on the Internet. We don't realize but we're surrounded by possible dangers that may harm us or involve us in crimes. We can find two main possible dangers related to Internet connection:

# Accessing fake Wi-Fies
When you are in a public place you will often find some free Wi-Fi. Well, it's sometimes a wifi from the specific place but it's sometimes a fake created by someone to catch your information, and depending on the information you have compiled in your Internet connexion, the hacker can access your accounts, watch and use your media files, supplant your identity... And it can be very dangerous for you, so be careful and try not to connect WiFies which are completely opened or which look suspicious.

# Leaving your WiFi connexion neglected, without enough security
It's not much problem if someone catches your WiFi password to use the Internet sometime, but it'll be a big problem if they use it to commit a crime or access your information as in the previous case. In our routers we usually have WEP (Wired Equivalent Privacy) encryption codes, which are weak and easily decoded, and worse if we don't change the default codes. If you want to be safer, at least you should have WPA (Wi-Fi Protected Wireless), whose algorithm is stronger. But the safer and difficultly decoded encryption protocols are WPA2, with Advanced Encription Standard. Whatever you have, try to make it secure, change the name and the password, hide any weak point...

I wish it was useful and you liked, see you next post, as always ;)

Social Networks in Prezi

Welcome again to my blog with this new post. We're starting the third term and I have a lot of work for these easter holidays, but I'll explain you what we're doing in computing, as usual.


We have been made to make a Prezi presentation about Social Networks, which we are used to use every day.
Prezi is a webpage where you can login and make 3D presentations with cool transitions, very dynamic and original. When you set a background you travel through it and through each frame, with visual attraction, and you can add almost any kind of document. It is also interactive; you can go anywheree in the presentation.
As this program works through the Internet you can access your presentation whenever you need it, but you can also download it for your PC (paying, but you have a free sample period).

I leave here the link to my Prezi, I wish you like:
And if you don't have Adobe Flash Player or your computer doesn't let you see it, you can also watch it here or here.
See you next post and have a good holiday time :)
