Animated GIF


Hello to everybody ! In this activity we had to create an animated GIF using Gimp and then write our name somewhere. This is my plane!





Cartoonize my face

In this work, the objective was to cartoonize our head using Gimp. After looking some cartoons, I decided to cartoonize my head into Son Goku! This is the result.


7up Logo

Hello!! This time, we were expected to try to "copy" the best as we could one logo. My logo was 7up's one.
Here yo can see the result.
This one is my result

This one is the real one

Nico Potter

Hello another time! This time, our homework was put our face, in a famous face, using another time Gimp 2.6. This time we had to "play" with layers, transparencies, colours... Here you have my result:


Students collage

Hello everybody, in this activity we had to insert all of us using the program Gimp 2.6, and we worked with path tools, layers and transparencies: Here you can see my result:


Books prices 2

In this activity, we had to do the same than another work, but including more conditions about discounts and taxes, using OpenOfficeCalc.


Books prices

In this exercice, we had to calculate, the price of the books of a year applying discounts and taxes using the program: OpenOfficeCalc.

Information technologies questions


1. When did Videogames appear and what did they look like? Lisa
Videogames  appeared in the 40s, after the Second World War. The firsts videogames were very simple, without movements in the screen and with very few options to play.

2.What is a MODEM and what is it used for?  Jandro
The modem is a device that modulates an analog signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. It is used for produce a signal that can be transmitted easily and decoded to reproduce the original digital data.

3.Why ADSL can transmit the digital information at the same time than conversations? Jandro

Because ADSL uses frequencies that aren't used by a voice telephone call. A splitter, or DSL filter, allows a single telephone connection to be used for both; ADSL service and voice calls can occur at the same time.

4.What are artificial satellites used for? Name the first one. Suany
Artificial satellites are used to send information through the air. The first satellite was the Sputnik (1957).

5.How the GPS receiver calculates the position?Suany
The GPS send the information to three satellites that calculate the position of the GPS and send the information another time to the device.

6. Which devices are used as external memories? Javi
The most common device used as external memories is the hard disc but there are other devices: flash drives (pendrives), memory cards...

7.Explain the four generations of mobile technology, indicating the improvements of each. Ana
1st generation: It appear the first cellular phone and the first telephone companies. The first phone call was made it by Vodafone in 1985.
2nd generation: In this generation, phones became smaller and have new applications as batteries or electronics. Telephonic companies insert SMS that are text messages. The first SMS was sent in Finland, 1993.
3rd generation: Mobiles became smaller and started to be more usefull and a leisure device. Phones with radio and television or Internet and Wi-Fi were common in this generation.
4th generation: This generation was important because, mobiles of the 4G were about 10 times faster than the 3G ones. New applications and tools were disegned on the phone, now cellulars had camera, Mp3 recording, video player, videogames, large memory...

8.Which are the differences by means of signal speed between optical and cupper wires? Jandro
The main difference is that optical wires are especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables (cupper wires). Because of its advantages over electrical transmission (faster) , optical fibers have largely replaced copper (Cu) wire communications in in the developed world.

9.Explain the basis of image generation in cathode ray tube screen. Differences in colour and black-and-white TV. Annika

10. Which is the role of Modem in LAN? Federico
The role of Modem in LAN is to increase the speed of the users and a bigger access than the analogical connection.

11.  Why are internet models OSI and TCP/IP divided into layers? How do these protocoles work? Laia
This Internet models are divided into layers because each layer provides specific services and makes the results available to the next layer. Theoretically each layer should be independent of all others.

12. What is a MAC address? Ashley
A MAC address is a hardware identification number that uniquely identifies each device on a network. Each device needs to have a unique MAC address. MAC addresses are made up of six two-digit hexadecimal numbers, separated by colons. Like for example; 00:0d:83:b1:c0:8e

13.Who invented the screw-press and why was it so important? How written information was broadcasted before it? Explain these ideas. Claudia
The screw-press was invented by Johann Gutemberg and it was so important because now, books, information, could be stamped in paper. Before the invention of the screw-press, information was broadcasted through paintings, sounds, signals, shouts...

14.  What do we call Multimedia to? What is it used for? Lisa
 Multimedia is any combination of text, graphic art, sound, animation, and video that is delivered by computer. It is used to describe multiple forms of media and content.

15. Differences between first and last generation of cellular phones. Ana
In the 1st generation, phones could only made calls from person to person in short distances. The last generation of cellular phones is caracterized because those phones have lots of applications as radio, internet, lots of tools as GPS, Mp3 recorder, video player.. and are much faster and usefull.

16.What is a network protocol and how does it work? Federico
A network protocol is a rule or a convention that facilitates device identification and data transfer. Protocoles use packet techniques to send and receive the information. A protocole work through independent layers that have specific functions.

17. Which are the applications for instant communication? How do them work in terms of network? 

18. Which were the first machines that made numeric calculations for the first time? Explain a little their working. Ellie.
The first machines that made numeric calculations were the Abacus, the Napiers Bones and the Slide Rule.
The Abacus works: Each bead above the beam in the middle is the equivalent to 5 and each bead below is the same as 1. It was a very simple way of adding and subtracting. You use either the units, tens, hundreds or thousands as you would if you were writing them down. You push the beads that you use closer to the beam and those are the ones you subtract or add.
The Napiers Bones it was a very complicated way to do complex equations.
The slide rule is used mainly for multiplication, division, square roots, logarithms and trigonometry.

19. Which devices became more important from screw-press up to telephone? Explain them a little. Isabella.

20. Which was the first wire transmission? Explain its evolution and the phone networking nowadays. Nico
The telegraph was the first wire transmission. With the pass of time, the information sended through wires, was sended by larger distances and then it appears the telephone. Nowadays, the information can be sent in lots of ways: optical fiber, satellites, cellular networks, microwave transmission or by wires.

Facebook page

In this activity, we were expected to create a Facebook page, using only OpenOffice some pictures, and our imagination!


Telegraph and wire comunication

In this activity, we had to talk about the history of the communication technologies. I had to talk about the wire communication and the telegraph. Here you have my work.
Telegraph and wire communication: phone

The telegraph.

The telegraph was created in 1837 by Samuel Morse, in consequence of pacience and perseverance, but the first telegraphic line didn't arrive until 1844, the message was sended from Washington to Baltimore (57.2 km). He created an electrical telegraph that was superior from the others.

The telegraph was a very important invent and it worked like this:
The battery sends a current to an electromagnet placed on a receiving station. The current is transportated into a simple wire. When the current arrives to the electroimant, the information is sended to an awl that writes in a paper roll that passes throught an ink roller situated down the awl. The awl writes the information sended in the paper using an special code, the Morse code.
In 1850, the telegraph had expanded in North America, England and some countries of Europe.
In 1851, a cable, joined Europe and Africa and other islands situated in the Mediterranean Sea. People started to realize that connection throught the Athlantic Ocean won't be to much difficult.

Wire communication: the phone

Lots of people think that Alexander G. Bell invent the phone in 1876, but the truth was that the phone was invented by Antonio Meucci in 1871. Bell had only improve and complete Antonio's project.





The idea of the telephone began when Antonio Meuccis's wife was ill, and he wanted to connect his office and the room where his wife was resting. But Antonio had not so much money to show his project to people. In 1871, he could only present a little part of the telephone, he named it, teletrophone.

The first telephone only had a reciever, a transmitter and a single wire where the information passes trought. The reciever and the transmitter had a magnet that makes vibrate a diaphragm that turns the vibrations into sounds.
