1. (Christopher)With packet-switched networks its services allow
multiple connections to exist simultaneously over the same
physical circuit, like that of a Local Area Network (LAN) or a
Backbone Network (BN). An example of a packet-switched
network is the internet, which is based on the TCP/IP protocol
suite. Where a series of routers located at different points on
the Internet's backbone transmit each packet received based on
its destination address until the packet reaches its destination.
By contrast, circuit-switched networks or dedicated networks
require a dedicated path between the source and the destination
before the transfer of data can begin. Additionally, data
transmission is guaranteed but by only two devices and it is
used primarily for connections that must be continuous for long
periods, such as long-distance communication A good example
of a circuit-switched network is a traditional telephone system
or landlines (FitzGerald, 2021).
One difference between switched backbone networks and routed
backbone network is most organizations place all network
devices for one part of the building in the same room located in
a rack when using switched backbone architecture. The
advantage of this placement is easy maintenance and upgrade.
Additionally, switched BNs use a star topology with one switch
in the center. By contrast, routed backbones LANs employ their
own router, and each router is connected to a core router, which
breaks the network into separate subnets. The LANs in one
building is separate from the LANs in other buildings.
Therefore, message traffic stays in one subnet unless needed in
other parts of the network. The advantage of a routed backbone
is it segments each part of the network connected to the
backbone. The disadvantage of routed backbones is routers are
more expensive and slower than switches and require more

HIS 200 Historical Analysis Essay Progress Check 3 Guidelines
and Rubric
Overview: Throughout Modules Seven and Eight, you have
continued to work on your Project 2: Historical Analysis Essay
assignment, which you will formally
submit for completion at the end of Module Eight of the course.
This progress check assignment provides you with an important
opportunity to get valuable
instructor feedback on the progress you are making and to
ensure you are on the right track for your later submission.
Prompt: Module Seven: Thinking About History has considered
how historians communicate their historical event’s complexity
to a specific audience. Return to
your submission for Progress Check 2 and add a paragraph
describing the complexity of your chosen historical event.
Review your final writing plan submission
and reflect upon what you wrote previously about your essay’s
intended audience and message. Implement revisions to make
sure that your essay’s message is
effective and tailored to your specific audience. Revisit Module
Four: Communicating Historical Ideas, continued, learning
block 4-2 in the webtext, if you need
a refresher on communicating to your specific audience.
Specifically, in this assignment, you will submit the following
elements of your Project 2: Historical Analysis Essay for review
by your instructor:

3. In Module Seven: Thinking About History, learning block 7-3
(page 3) in the webtext, you worked toward the following
elements:
II. Body: You will use this section of your essay to provide
further detail about your historical event while supporting the
claim you made in your thesis
statement. Make sure to cite your sources. Specifically, you
should:
A. Describe the causes of the historical event. In other words,
what were the underlying factors that led to the historical
event? Were there any
immediate causes that precipitated the event?
B. Illustrate the course of your historical event. In other words,
tell the story or narrative of your event. Who were the important
participants? What
did they do? Why? How do the perspectives of the key
participants differ?
C. Describe the immediate and long-term consequences of the
historical event for American society. In other words, how did
the event impact
American society?
D. Discuss the historical evidence that supports your
conclusions about the impact of the event on American society.
Support your response with
specific examples from your sources.
In Module Seven: Thinking About History, learning block 7-3
(page 3) in the webtext, you completed the following element:
V. Communicate your message in a way that is tailored to your

4. specific audience. For instance, you could consider your
vocabulary, your audience’s
potential current knowledge of historical events, or lack thereof,
and what is specifically important to the audience.
Please note that the numbering included above directly aligns
with the numbering of these elements as they are presented in t
he Project 2 Guidelines and
Rubric. You will ultimately also need to include a conclusion
and reference list and make sure you communicate your essay’s
overall message in your final
historical analysis essay, but you do not need to do so in this
submission. You will be prompted to build upon this progress
check submission to prepare your final
historical analysis essay for submission in Module Eight.
