PERSONAL PROTECTION AND DATA PROTECTION →Hello again!!! in today's class we have learned about personal data protection. Next we will talk about information that we all need to know when using devices. Nowadays we use technologies and devices for everything, that's why we should know that we are exposed to have our accounts hacked. We have to be careful when putting passwords or user numbers on pages that are not very secure.  Installing things like Antivirus or Malware Detection Tool will allow us to stay away from this type of hackers.

 INNOVATIVE AND CREATIVE USE OF

 DIGITAL TECHNOLOGY

→Hi everybody!!

If the resolution is not very good, we will be able to see the pixels clearly. Raster image formats are divided into compressed (PNG, JPEG, ...) and uncompressed (PSD, RAW, ...). 

Another type of image are vector images, these are mathematically defined shapes, they are resolution independent. For this type of format we can use PDF, PS,...

On the other hand, if what we want is a sound format and with quality, we will use WAV, AIFF, FLAC. When we use MP3 or AAC the quality is lost. For video formats, MPEG, MPEG-4 are normal. For the creation of a Podcast, iVoox is a good example, it allows us to upload various types of format.

Finally, in today's practice we have worked with the GIMP program. This program allows you to edit photos by adding text, drawing or even adding filters. You can also crop and create new collages. Here are the examples we had to make.
