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. Since there are malicious programs that seek to obtain personal data and money. It is also advisable to renew passwords from time to time and not to use the same password for all accounts. In addition to this, it is also advisable to use secure passwords, which are those that contain a combination of uppercase and lowercase letters, as well as numbers.  Another thing we can do to avoid obtaining our data is to delete cookies, because every time

 DIGITAL CONTENT, INFORMATION,

EVALUATION AND LICENSING

→ In today's class we have learned about what a digital content is and also the types of software that exist as well as the types of licenses it has. 

A digital content is any form of data or information in digital form (such as electronic files), as opposed to physical form. 

There are two types of software:

  • System software: like Windows, Android, IOS.
  • Application software: Word, Photoshop, Teams.

We can classify the software in 4 types from the point of view of the license:

       Traditional licence (Copyright), Free software, Freeware, and Shareware.

We also learned about Intellectual Properties, which refers to creations of the mind and is the set of rights that authors have over their original creations. And finally Creative Commons, which consists on a non-profit organization dedicated to provide free permission to the public to share and use their creative work under the terms and conditions of their use. They can be grouped into 4 modules of conditions:

      Attribution (BY), Share equal (SA), Non-commercial (NC), Non-derivative (ND)

And by the combination of these modules we get six Creative Commons licenses as we can see in the picture below.

CLOUD DATA STORAGE AND RETRIEVAL →   Today we have learned the different types of cloud storage and how to recover the data. Cloud Computing is a paradigm that makes it possible to offer computing services (storage, content creation, blogs, wikis, streaming, social networks) over a network, usually the Internet. Everything that a computer system can offer is offered as a service. FEATURES: On demand service, you use it when you need it.  Network Access (Internet).  Shared resources, used by multiple clients.  Scalability, allows elasticity of resources. TYPE OF CLOUDS: Public Cloud : maintained and managed by third parties not related to the organization. ( Google Drive ) Private Clouds : are on-demand infrastructure, managed for a single client that controls which applications should run where. ( for companies, big organizations ) Hybrid clouds : combine public and private cloud models. ( Hotmail ) DELIVERY MODELS OF CLOUD COMPUTING Software as a Service (SAAS): access from anywhere,

  INNOVATIVE AND CREATIVE USE OF  DIGITAL TECHNOLOGY →Hi everybody!! Today's class has been based on what is multimedia and the creative use it has. We can find types of images like a Bitmap , this is a rectangular grid of pixels, the result obtained will depend on the quality of the resolution. 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

→ Hello again!!  next we will work only with scratch, so the posts I will upload will be related exercises.  For this exercise the goal was to create our name using the letter sprites. To each letter we assign a different function. In the picture below I show you where you can change the sprites and background: In my case the L changes color, the U changes its position when you touch it, rotating 15 degrees each time. On the other hand when pressing the C sounds a sound, with the I sounds the sound of the drum and the letter moves around the screen. And finally the A changes its size.
