Redes Informaticas

JUSTIFICATION

The objective for the thesis consist in resolve the doubts that we have about networking computer.
The information is very simple but in the reality is a complex issue. We are going to try to resolve all doubts about the subject.
We have an idea to resolve all these questions. We create a duplan(note 1) and make a CD. This CD is for students of 4,5,6,7 grades they are goingto understand more about the project and enjoy the activity. Also it´s going to be didactic and easier to understand and learn

GENERAL PURPOSE

The objective of this work is to be of great help to people who have too many questions to resolver. On the subject of computer networking.
This project is aimed for young people because they are the most used this measure and are the most mishandlinggive to be a dangerous half

SPECIFIC OBJECTIVES

* To help to solve the doubts of the users

* To learn the good use of the IT networks

* To know the advantages that it has the companies with the use of the IT networks

* To know the types of networks that exist

* To manage to do a deep investigation on the topic

INTRODUCTION

Feeling conscious ofhis creative ability, methodically elaborate procedures to organize their knowledge, resources and manipulate their environment for your comfort, promoting science and improving their quality of life by sacrificing the natural development of their environment, producing all the advances that a large segment of the population know: automobiles, airplanes, ocean liners, telephones, televisions andso on.
I think processing units faster and faster, divided into four generations well defined: the first with vacuum tubes, the second transistor, the third integrated circuit, the fourth integrated circuit that allowed the use of personal computers and the development of data networks.
This last element computer networks, is to “share resources”, and one of its main objectives is to make allprograms, data and even the teams themselves available to anyone who requests it, regardless of physical location own resource and user.
Each evolution has its profits by leveraging technology we know that we offer today has had many benefits for society because it uses technological intelligence are very helpful. Computer networks are critical because it allows the connection to technology andhelp develop globally.
Current technology has taken mind much empowering worldwide have grown computer, phone, televisions, all thanks to computer networking

1 TIPOS DE REDES
1.1 REDES COMPARTIDA
Son aquellas a las que se une un gran número de usuarios, compartiendo todas las necesidades de transmisión e incluso con transmisiones de otra naturaleza
1.2 REDESEXCLUSIVAS

Son aquellas que por motivo de seguridad, velocidad o ausencia de otros tipos de red, conectan dos o más puntos de forma exclusiva, este tipo de red puede estructurarse en redes puntos a punto o redes multipunto

1.4 REDES PUBLICAS

Son aquellas que pertenecen a organismos estatales y se encuentran abiertas a cualquier usuario que lo solicite mediante el correspondiente contrato.

2 TIPOS DE DIRECCIONALES
2.1 SIMPLEX UNIDIRECCIONALES
La transmisión simplex (sx) o unidireccional es aquella que ocurre en una dirección solamente, deshabilitando alreceptor de responder al transmisor. Normalmente la transmisión simplex no se utiliza donde se requiere interacción humano-máquina. Ejemplos de transmisisón simplex son: La radiodifusión (broadcast) de TV y radio, el paging unidireccional, etc.

2.2 HALF – DUPLEX
La transmisión half-duplex (hdx) permite transmitir en ambas direcciones; sin embargo, la transmisión puede ocurrir solamente en...
