Outcome
|
For all of the following student
competencies, the level of mastery is moderate; the
level of knowledge is to define, identify, and
measure; and the assessment tools will be tests and
quizzes, papers, class participation, and
cases.
The student should be able
to:
- Identify the characteristics
of connectionless and connection-oriented
networks.
- Differentiate between a
process, a service, and a protocol.
- Explain why protocols are
arranged in layers.
- List the ways in which two
processes can cooperate in a layered
architecture
- Define the effects of
changes to layers within a layered
architecture.
- Characterize the differences
between data communicated by the lower layers
and by the upper layers.
- Explain the flow of data
encapsulation in a layered
architecture.
- Name the lower layers of
the OSI model and give their relative
position in the stack.
- For the physical, data
link, network, and transport layers, you will
be able to:
- Describe the service that
the layer provides to the layer above
it
- Name some of the common
protocols used by each layer
- Identify the function and
benefit of the multiplexing and
parallelization provided by the transport
layer.
- Explain how the lower
four layers, taken collectively, differ from
the upper three layers of the OSI model.
- For the Session,
Presentation, and Application Layers, name
common protocols used by each layer.
- For the Session and
Presentation Layers, describe the services
that the layer provides to the layer above
it.
- Name the important
network applications and briefly describe the
services provided by each.
- State important
characteristics that TCP/IP, SNA, and DNA
(DECnet) have in common or that set them apart
from one another.
- Identify important
characteristics of baseband and broadband
transmission and give the important
characteristics of the baseband
standards.
- Contrast the characteristics
of bus, pure ring, and star ring
topologies.
- Identify the components of
the OSI 8802 (IEEE 802) protocol suite, showing
their relationship to one another.
- Explain why collisions occur
in a CSMA/CD network.
- Explain CSMA/CD message
transmission logic.
- Give the types and number of
tokens that circulate on a Token
Ring.
- Explain how tokens are
inserted onto and removed from a Token Ring and
Token Bus.
- Explain why Token Ring and
Token Bus exhibit better performance
characteristics than CSMA/CD under conditions of
heavy load.
- Give the rationale for
FDDI's dual rings.
- State the maximum throughput
of the Ethernet, Token Ring, Token Bus, and FDDI
LAN Standards.
- Given a user's requirements
for a LAN, identify the LAN architecture that
best addresses those needs.
- Understand the frame formats
used for the LAN topics discussed.
- Understand the three major
types of computing platforms.
- Understand the features of
Desktop Computers (PCs and
Workstations).
- Understand the usage of
Midrange (sometimes called midframe)
Computers.
- Understand the usage of
Mainframe Computers (also called hosts or host
CPUs).
- Name the primary advantages
of the client/server model when used in PC
network environments.
- Indicate the advantages of
Remote Procedure Call tools to developers of
network applications.
- Identify the generic mapping
of PC LAN Network Operating Systems to the OSI
model.
- Identify primary products
and product characteristics of the leading PC
LAN vendors.
- Identify major trends in the
PC LAN marketplace.
- Identify the TCP/IP layers,
their components, and their functions. Name the
OSI layer that
- corresponds to each TCP/IP
layer.
- Identify the components of a
class B Internet address in the dotted decimal
form.
- Give the general form of a
hierarchical Internet name.
- Explain how LAN addresses
are determined.
- Give the purpose of the ARP
cache and state what is stored in it. Tell how a
gateway node differs from an ordinary
node.
- Characterize the delivery
service provided by IP and TCP.
- Identify the reasons that an
application might use UDP.
- Identify the services that
six important TCP/IP applications
provide.
- Identify internetworking
components such as repeaters, relays, bridges,
routers, switches, hubs and
gateways.
- Identify the layer of the
OSI model that corresponds to the different
types of internetworking components.
- Identify the types and
functions of the various bridging and routing
methods.
- Understand when to bridge,
route or switch.
- Understand the functions and
uses of a TCP/IP router.
- Understand what takes place
when routing data over an internet.
- Identify the
major problems that can be solved using a
protocol converter.
- Understand network
management issues and concerns.
- Understand the different
types of WAN connections.
- Understand basic
telecommunications services.
- Identify some of the
components used to make the
connections.
- Understand when to use each
component.
