2. Relacionar los componentes de los hubs, de
los switches y de los routers conforme la
explicación del maestro.
Documentar los diferentes componentes
relacionando con cada función de acuerdo al
diagrama de bloques del router.
4. El hub (concentrador) es el dispositivo de conexión
más básico. Es utilizado en redes locales con un
número muy limitado de máquinas. No es más que
una toma múltiple RJ45 que amplifica la señal de la
red (base 10/100).
En este caso, una solicitud destinada a una
determinada PC de la red será enviada a todas las
PC de la red. Esto reduce de manera considerable
el ancho de banda y ocasiona problemas de
escucha en la red.
5. El Switch (o conmutador) trabaja en las dos
primeras capas del modelo OSI, es decir que éste
distribuye los datos a cada máquina de destino,
mientras que el hub envía todos los datos a todas
las máquinas que responden.
Concebido para trabajar en redes con una cantidad
de máquinas ligeramente más elevado que el hub,
éste elimina las eventuales colisiones de paquetes
6. El Router permite el uso de varias clases de direcciones IP
dentro de una misma red. De este modo permite la creación
de sub redes.
Es utilizado en instalaciones más grandes, donde es necesaria
la creación de varias sub redes.
Los routers son compatibles con NAT, lo que permite
utilizarlos para redes más o menos extensas disponiendo de
gran cantidad de máquinas y poder crear “correctamente” sub
redes.
También tienen la función de cortafuegos (firewall) para
proteger la instalación.
9. Description:
The DP83924B Quad 10Mbps Ethernet Physical Layer
(4TPHY) is a 4-Port Twisted Pair PHYsical Layer Transceiver
that includes all the circuitry required to interface four
Ethernet Media Access Controllers (MACs) to 10BASE-T.
This device is ideally suited for switch hub applications
where 8 to 32 ports are commonly used.
The 4TPHY has three dedicated 10Base-T ports. There is
an additional port that is selectable for either 10Base-T or
for an Attachment Unit Interface (AUI). In 10Base-T mode,
any port can be configured to be Half or Full Duplex.
10. Features
100 pin package
n 10BASE-T and AUI interfaces
n Automatic or manual selection of twisted pair or Attachment
Unit Interfaces on port 1
n Direct Interface to NRZ Compatible controllers
n IEEE 802.3u Auto-Negotiation between 10Mb/s Full
and Half Duplex data traffic and parallel detection
n MII-like Serial management interface for configuration
and monitoring of ENDEC/Transceiver operation.
Programmable MAC Interface supports most
standard 7 signal MAC interfaces
n Twisted Pair Transceiver Module
Serial LED interface for LINK, POLARITY, ACTIVITY,
and ERROR.
n JTAG Boundary Scan per IEEE 1149.1

12. Description
Pulse’s 10BASE-T Quad SMT Transformer Modules are designed to
interface with transceiver chips offered with internal wave shaping and
filtering.
The Pulse PE-68050L, PE-68065L and E5007 contain transmit and
receive isolation transformers to maintain signal integrity, suppress
common mode noise, and supply equipment isolation per the IEEE 802.3
standard.
The Pulse PE-68049L, PE-68062L and E5002 provide transmit and
receive isolation tansformers as well as the high impedance common
mode chokes.
The common mode chokes are incorporated for added EMI suppression
and are often necessary for FCC and CISPR 22 Class B certification.
13. Los routers de la serie Cisco 3800 de servicios integrados

Ambos admiten tarjetas de interfaz WAN (WIC), tarjetas de
interfaz de voz/WAN (VWIC), tarjetas de interfaz WAN de alta
velocidad (HWIC) y módulos de integración avanzada (AIM).

19. The MPC860 PowerQUICC is a versatile one-chip integrated
microprocessor and peripheral combination that can be used in a variety
of controller applications, excelling particularly in communications and
networking products.
The PowerQUICC can be described as a next-generation MC68360
QUICC for network and data communication applications, providing
higher performance in all areas of device operation including flexibility,
extensions in capability, and integration.
The MPC860 PowerQUICC, like the MC68360 QUICC, integrates two
processing blocks. One block is the embedded MPC8xx core and the
second block is a Communication Processor Module (CPM) that closely
resembles the MC68360 CPM. The CPM supports four serial
communications controllers (SCCs) on the device; however, there are
actually eight serial channels—four SCCs, two serial management
controllers (SMCs), one serial peripheral interface (SPI) and one I2C
interface. This dual-processor architecture provides lower power
consumption than traditional architectures because the CPM off-loads
peripheral tasks from the embedded MPC8xx core.
