INTRODUCCIÓN

Un conmutador o switch es un dispositivo digital lógico de interconexión de equipos que opera

en la capa de enlace de datos del modelo OSI. Su función es interconectar dos o más segmentos

de red, de manera similar a los puentes de red, pasando datos de un segmento a otro de acuerdo

con la dirección MAC de destino de las tramas en la red.Un conmutador en el centro de una red

en estrella.

Los conmutadores se utilizan cuando se desea conectar múltiples redes, fusionándolas en una

sola. Al igual que los puentes, dado que funcionan como un filtro en la red, mejoran el

rendimiento y la seguridad de las redes de área local.

2.De acuerdo al video elabore un glosario de 20 palabras técnicas en ingles con sus respectivo significado

1) Switch: is a special purpose device designed to solve performance problems in the network, because of small band widths and traffic jams. The switch can add more bandwidth, accelerate packet output,

reduce waiting time and lower cost per port.2) Node: In computing and telecommunication , in a very general way a node is a point of

intersection, connection or union of several elements that come together in the same place.However, within the computer node word can mean different things depending on the area in which we move

3) Ethernet: (also known as IEEE 802.3 standard ) is a data transmission standard for local area networks which is based on the following principle

All devices on an Ethernet network are connected to the same communication line composed of cylindrical wires.

they are connected to the same line of communication, composed of cylindrical cables

Different variants of Ethernet technology are distinguished according to the type and diameter of the wires used

4) link: is text or images on a website that a user can click to access or connect to another document. Links are like the technology that connects two sites or two websites. In the browser look like underlined words (such as To the list of FAQ's at the bottom of this page).

5) Wire: is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number

6) Host:  is used in computing to refer to computers connected to a network , providing services and use it. Users must use hosts to access the network.In general, the hosts are single-user or multi-user computers that offer file transfer , remote login, server database , web servers , etc.

7)  network port:  is an interface to communicate with a program through a network . In the OSI model who is concerned with the administration of ports and set in the header of the segments is the transport layer or layer 4, thus managing the sending and re-assembly of each segment sent to the network using port Specified

8) Twisted pair: cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from unshielded twisted pair (UTP) cables, and crosstalk between neighboring pairs. It was invented by Alexander Graham Bell

9) Hub: is a device that enables centralized wiring a network and to enlarge. This means that the device receives a signal and emitting it repeats the signal from different ports. Work at the physical layer (layer 1) of the OSI model or access layer in TCP / IP model.

10) router : also known  router packet and hispanicized as router - one is a device that provides connectivity to network level or third level in the OSI model . Its main function is to send or route data packets from one network to another, ie, interconnecting subnets , meaning subnet a set of machines IP that can communicate without the intervention of a router (via bridges ), and therefore having different network prefixes.

11) MAC address: is an identifier of 48 bits (6 blocks hexadecimal ) corresponds uniquely to a card or device net . Also known as physical address , and is unique for each device. Is

17

determined and set by the IEEE (the last 24 bits) and the manufacturer (the first 24 bits) using the organizationally unique identifier . Most protocols working at Layer 2 of the OSI model using one of three numbering handled by the IEEE : MAC-48, EUI-48 and EUI-64, which are designed to be globally unique identifiers.

12) Protocol: One or a set of procedures to standardize a human or artificial systematic behavior against a specific situation.

13) full-duplex: data can be transmitted in both directions on a conveyor of signals at the same time for servi. EXAMPLE by, in a local area (LAN) network with a technology that enjoy transmission full-duplex, a working florist be sending data station on the line while another workstation is not to receive other data

14) buffer amplifier: is a device that couples impedances in a circuit. In its simplest form is a complement to function as a supporter. Therefore the voltage and current does not diminish in the circuit, since this takes the voltage of the power supply of the operational and not the signal that is being introduced, so if a signal with little current, the follower circuit would offset that loss with the op-amp power supply, either unipolar or bipolar.

15) data transit: is when a physical link. the data link layer deals with the physical addressing (compared with the logical), network topology, network access, notification of errors, delivery intercept of frames and flow control.

16) patch panel: also called bay or patch panel routes, is the element responsible for receiving all cables structured cabling. It serves as an organizer of the connections of the network related to the elements of the LAN Network and connectivity equipment can be easily incorporated into the system and also the connection ports of active network equipment

17) IP address: is a numerical label that identifies, in a logical and hierarchical, way to interface (communication/connection element) of a device (usually a computer) within a network that uses IP (Internet Protocol) Protocol, which corresponds to the level of the OSI model network. This number is not to be confused with the MAC address, which is a 48-bit identifier to uniquely identify the network card and does not depend on the connection protocol used or of the network

18) Broadcast: it is a form of transmission of information where a sending node sends information to a multitude of receivers nodes simultaneously, without having to reproduce the same transmission node-by-node

19) Datagram: each packet is treated independently, each containing the destination address. The network can route (via a router ) each fragment to the Data Terminal Equipment (DTE) receptor by different routes. This does not guarantee that packets arrive in the right order, or that all reach the destination.

20) Address Resolution Protocol It is a protocol of the link layer data responsible for finding the address hardware (Ethernet MAC) corresponding to a given IP address. So a packet is sent (ARP request) to the network broadcast address

Conclusiones

En la anterior guía se aprendieron cosas muy importantes que no van a servir en el transcurso de nuestra vida profesional se identificaron los diferentes comando para resetear y configurar un switch

Aprendimos a interconectar dos computadores mediante un switch Practicamos el inglés tanto escuchándolo como escribiendo y pronunciándolo algo que es

muy importante ya que hoy en día el inglés ha tomado gran importancia en el mundo y es algo indispensable que todos debemos saber

Se identificaron los diferentes términos técnicos con sus respectivas respuestas en ingles
