Therefore, you get to choose the manner in which the effects take place, control the amount of time for the effects, and preview them like they were final products.

Optimization

With VideoPad, you can easily add digital images and pictures, while also adjusting the brightness and contrast for your video. You can create effects similar to those found in old images and videos by applying the black and white effects. You can also play around with the sepia and negative toned effects. VideoPad allows you to input text or captions onto the video as well. There is also a set of great audio tools to experiment with.

You can even input your own words into a narration on the video or if you have an existing one, you can simply import that to be added to the final product.

Computer security

Computer security (also known as cybersecurity or IT security) is information security as applied to computing devices such as computers and smartphones , as well as computer networks such as private and public networks, including the Internet as a whole.

The field covers all the processes and mechanisms by which computer-based equipment, information and services are protected from unintended or unauthorized access, change or destruction.

GIMP

GIMP is a programm to edit pictures,it is difficult when you are a begginer, we worked with it in the computing class we did three works, the first one consisted in mix several layers, we used a background image of a place and then we used others pictures.

The second work consisted in use a picture of Juanelo our highschool and then we mix it with a picture of Don Juan Tenorio.

The last work consisted in use a fruit backgound image and then mixing layers of faces, and finally you get a funny fruit.

Computer Network

A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users. Networks are commonly categorized based on their characteristics.

Types of Computer Networks:

• Depending on its size or coverage area:

-LAN (Local Area Network):It is a computer network that use interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. 

 -PAN (Personal Area Network):A personal area network (PAN) is a computer network used for data transmission among devices such as computers, telephones and personal digital assistants. PANs can be used for communication among the personal devices themselves (intrapersonal communication), or for connecting to a higher level network and the Internet (an uplink).

PAN.

   -WAN (Wide Area Network):is a network that covers a broad area (any        telecommunications network that links across metropolitan, regional, or national boundaries) using private or public network transports.

WAN

-MAN (Metropolitan Area Network): It´s for a city.

MAN

                                                     

•   Depending on your level of access or privacy:

-Internet :It is a worldwide network of computer networks. Have    public access.

 -Intranet: It is a local network that uses Internet tools (web, mail, ftp, ...). It can be considered as a private Internet which operates within the same institution.

-Extranet:  It is a virtual private network, that is part of the Intranet of an organization extends beyond users.

• According to their functional relationship:

-P2P(Peer to Peer): All devices can act as clients or servers.

-Client-Server : The client–server model of computing is a distributed application structure that partitions tasks or workloads between the providers of a resource or service.     

• According to the typology:                                                                                                                                                                                                                                                                                                  
• According to physical medium:

-Wireless: Wireless networks are computer networks that are not connected by cables of any kind.

 -Mixed :

-Wired:A wired network is one  in wich all the components are conected with networks cables.                                                                                                    

Characteristics of computer network

The computers are comunicated through a protocol with numerical adress,it´s the IP.

An IP address is a numerical label that identifies a logical and hierarchical manner, to an interface (communication element / connection) of a device (usually a computer) within a network using (Internet Protocol) IP protocol, which corresponds at the network layer of the OSI model.

• Types of IP :

-Type A: they are the networks with a IP direction between 0.0.0.0 and 127.0.0.0.

-Type B: they are the networks  with a IP direction between 128.0.0.0 and 191.0.0.0.

-Type C: they are the networks with a IP direction between 192.0.0.0 and 223.0.0.0.

QR codes

Código QR (abreviado a partir del código Quick Response). El código QR es un sistema que almacena información acerca de una matriz de puntos o de código de barras de dos dimensiones. El código consta de módulos de negro dispuestos en un cuadrado sobre un fondo blanco. La información codificada puede ser texto, URL o de otros datos. Sus tres esquinas cuadradas permiten al lector a determinar la posición exacta de hacer. El sistema de puntos fue creado por la compañía japonesa Denso-Wave en 1994.

Phubbing

For about five years ago, we've all experienced at least once "phubbing" during a meeting or a family meal. This massive practice lacked a name until recently but its consequences were significant for everybody. It began the year 2007 with the birth of the smartphone or smart phone, summarizing in a few inches the power of a desktop computer. With the ability to stay connected to the Internet anytime and anywhere, this obsessive practice that perpetuate many without even knowing it was generalized. 

The "phubbing" (a term formed from words phone and snubbing) is the act of belittling who accompanies us to pay more attention to mobile or other electronics things  before than pay attention to the person. It has recently been named in U.S.

Selfie

A picture taken of yourself that is planned to be uploaded to Facebook, Myspace or any other sort of social networking website. You can usually see the person's arm holding out the camera in which case you can clearly tell that this person does not have any friends to take pictures of them so they resort to Myspace to find internet friends and post pictures of themselves, taken by themselves. A selfie is usually accompanied by a kissy face or the individual looking in a direction that is not towards the camera.
