Selfie

A selfie is a type of self-portrait photgraph. It is associated with social networks like twitter or instagram, I don´t usually do selfies because I don´t like to pose. My last selfie was in the commercial centre with my friend Oscar. This is the origins of selfie: Robert Cornelius, an American pioneer in photography, produced a daguerreotype of himself in 1839 which is also one of the first photographs of a person. Because the process was slow he was able to uncover the lens, run into shot for a minute or more, and then replace the lens cap. He recorded on the back "The first light Picture ever taken. 1839."
One example of selfie is:

GIMP

GIMP is a page in which you can add one image to anothger and you can have a image like if you are in this place. The other day we do an image in which I put me in a famous school called Oxford because I want to study there. In the next work I did a lemon with a face of a person. We did another GIMP of Don Juan Tenorio and we put some images of the play in the underground of the IES Juanelo Turriano. One example of a GIMP:

networks

The past week we did an exam of a didactic unit called networks.
Network is a set of computers and electronic devices connected together aimed at sharing resources, information and services. We learn about types of networks, IP directions, etc.

QR code

A QR code is a useful for storing information on a dot matrix or two-dimensional barcode, characterized by the three squares that are in the corners and that detect the position of the code reader module aimed the code allow its contents to be read at high speed.
its capacity is 7,089 characters.

CPU

This is a my third work that I did, it contains information of the CPU, in this work I did it with my friends Raul and Sergio. The next day we have to explain it to the class so I´m going to prepare it. :)
A central processing unit (CPU), also referred to as a central processor unit, is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The term has been in use in the computer industry at least since the early 1960s. The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same.  A computer can have more than one CPU; this is called multiprocessing. All modern CPUs are microprocessors, meaning contained on a single chip. Some integrated circuits (ICs) can contain multiple CPUs on a single chip; those ICs are called multi-core processors. An IC containing a CPU can also contain peripheral devices, and other components of a computer system; this is called a system on a chip (SoC).  Two typical components of a CPU are the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and the control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

time line

In my second work I did a time line about the computer´s history and in it I write the six period of time begining in the first computer.
