MIS 589 Week 1: Introduction and the Application Layer – Discussion
Technology and Evolution
As you will discover this week through your studies, communications have gone through
some major changes throughout history. Explain how information systems from the 1980s
differ from information systems today. What networking and communications changes
were introduced in the past decade (2000s), and what were their implications?
MIS 589 Week 1: Introduction and the Application Layer – Discussion
The Application Layer (Graded)
The textbook and lecture explain that there are four fundamental application architectures
in use today: host-based architectures, client-based architectures, client-server
architectures, and peer-to-peer architectures. Do some research in the DeVry Virtual
Library (Under Course Home in the Student Resources section). Basedon your research,
what application architectures are most prevalent today? Under what architecture would
you classify technologies such as virtualization, cloud computing, and Web-based
applications? Last, what factors are involved in selecting the architecture that is right for
your organization?

Media Access Control (Graded)

As you may have discovered by reading your textbook, there are two sub-layers that
operate at the data link layer. The media access control (MAC) sub-layer controls the
hardware, so let’s focus on that aspect. The two approaches to media access control are

MIS 589 Week 4: Network and Transport Layers – Discussion
IPv4 versus IPv6 (Graded)
At the heart of the networking layer is addressing. IP addressing is used to locate
computers and other network devices across the Internet. Currently, IPv4 is the dominant
network addressing standard used on the Internet and within organizations. The problem
is that we have exhausted our public IPv4 addresses. IPv6 was developed in part to address
this very issue.
Do some research on IPv6 in the DeVry Library and on the Web.
What are some immediate differences in the two protocols? Does IPv6 provide operational
improvement, as well as increased address space? How has/will IPv6 impact organizations,
the Internet, and you at home?
MIS 589 Week 4: Network and Transport Layers – Discussion

Network and Transport Layer Protocols (Graded)
The Network and Transport layers are where the protocol suites TCP/IP reside. This suite
of protocols is critical to the operation of the Internet and organizations as we know them
today.
Do some research via the DeVry library, the Internet, and your textbook and list and
discuss three TCP/IP protocols.
What are the primary functions of the Transport and Network layers? What protocols do
you use each day?

components being a cable and hardware device. Business processes and needs ultimately
drive the type of cable media and hardware you select. What are these types of cables and
hard devices? What are the major functions of each of these devices? What factors might
determine how we select which ones are appropriate for our organization?

Internet Architecture (Graded)

The Internet is easily the mostly widely used and accessible network in the world. But how
is it constructed? Many say the Internet is simply many separate networks connected
together. ReadChapter 10 and look under the hood to see how the Internet is put together.
What are some key pieces of the basic architecture of the Internet? What redundancies are
built into the Internet, as presented in Chapter 10? Do some research on the current
architecture of the Internet and on any planned changes.

The Wild, Wild Web (Graded)

Although we have discussed how the Internet has been an invaluable tool for organizations
and people across the world, it has also had adverse impacts on these same groups. From
identity theft to denial-of-service attacks, networking technology is being harnessed to
harm people and organizations. Do some research and report a recent information security
incident. How could this incident have been avoided? What management challenges did
this incident present? Discuss which technology from Chapter 11 of your textbook could
have helped to prevent or minimize the impact of this incident.
MIS 589 Week 7: Network Design, Management, and Security – Discussion
Cost Justification (Graded)
Cost-benefit analysis for our network decisions is a critical skill and ability in IS
management. What could we do to impress the CFO with our submission? Let’s look at
what they believe is important in an article from the source, CFO Magazine‘s site. Our
ability to sell technology recommendations to management often requires providing cost
analysis and perhaps evenhard dollar benefits. How the CFO in your organization thinks
should be a good indicator of what will fly in terms of getting support from the finance
department. The CFO Magazine website almost always has some information or articles
related to technology or networking.
Go to the CFO Magazine‘s website found in the Webliography under CFO.
How could the articles or recommendations at the CFO site help your efforts? Are these
subjects where we should be looking to for future investments? How likely is your
organization to be looking at these?
