Exam 1 Study Notes Last Update: 09/27/2018 @ 2 PM
LAYOUT:
- 40
Multiple choice questions, 2 points each
- Questions
are pulled from a pool and in random question AND answer order; therefore,
no 2 tests are the same.
- 2
essay/fill-in-the-blank questions, 10 points each
- Testing Method - Online Via Blackboard
and password
- Test Date/Available: Thursday 09/27/2018 (email will be sent out when it is available) to Sunday at 7 PM
- Time: 2 hours from the time you begin,
single submission
- Content Covered: Class lectures, Power
Points, assigned homework, videos and Fitzgerald Chapters 1-5
RULES:
- This is an online test. YOU, the
student, should be taking the test. Nobody else is allowed to help you
take this test.
- You cannot ask any questions of a live
person regarding test content before, during or after the test.
- You may NOT print, copy or save
any part of this test other than submitting it for grading. Blackboard has
mechanisms that can track this while you are taking the test.
- You may not share any answers to any
questions with any other students in the class, even if they have told you
they have already taken the test.
- You may use your notes, books, power
point presentations, the internet or any other static information. Again,
you cannot ask for help from any other humans.
- If it is determined that any of these
rules are broken, you may be dropped from the class, receive a failing
grade for the class and you may also be subject to academic dishonesty
policies at the University.
GRADING:
- The test will be initially
electronically graded after you press the submit button. This is a raw
score and may not be your final test grade.
- If you feel that there are 2 possible
answers, choose the best one, but then email me your concern and reasoning
behind your answer. Occasionally
there are 1 or 2 questions are dropped from a test if they are determined
to be not legitimate or appropriate after the fact. If I determine there
are 2 correct answers for a question, or if the question is improperly
structured, I will remove it from the test and nobody will receive credit
for it. SO, for example, if there were 30 questions, and 1 was determined
to be invalid, your score would be the number of correct answers out of
29.
- Your test grade will either be available
immediately after you take the test, OR, if there is an essay or upload
component, the grade will be available 72 hours online after you submit
the test.
AFTERMATH:
- We
will discuss the test at the following class meeting, YOU SHOULD ATTEND.
This is your chance to dispute any questions and humble me in front of the
rest of the class.
- If
you missed the test, you may make it up ONLY with a valid medical excuse
OR if I have given you permission prior to the test day.
- If
you perform poorly on the test (i.e. lower than 50%), I suggest before
dropping the course, to come talk to me first. I will assign a W for your
grade if you drop.
TEST CONTENT:
Questions will come
MOSTLY from
the book, and the Power Point Presentations as well as any homework I
assigned you including any videos I asked you to watch, although it
would be a very good
idea to read my notes on each chapter. Pay attention to the
SUMMARY and
QUESTIONS in the back of each chapter. There will be no SPECIFIC
questions from
any of the case studies. It may be beneficial for you to search for
some of the
items on the Internet, e.g. ISO, ANSI, history of the World Wide Web,
on sites
such as whatis.com and google.com.
Please note that because of
the brevity of the test, I am not able to ask questions over all the topics
that I felt were important for you to know, otherwise the test would be 100+
questions. I placed less emphasis on physical technical issues and tried to ask
more questions about the background and functions of different levels and
protocols. I will ask questions about Netmasks and network addresses but you
will not be doing any math to determine subnet sizes. I will leave this for the
next exam.
(The
following datapoints possibly relate to at least one specific questions on the
test, although not in this order. Not all of these topics will be on your test.
There are multiple versions:
Chapter 1 -
Introduction to Data Communications
- Be familiar with
the Federal Judge order in 1984 that broke up "Ma" Bell and also
Telecommunications Act of 1996 and what impact it had on the industry.
- What changed in
1983 with respect to the Internet? What 2 parts were created?
- Describe the
difference and relative scope of a LAN, BN, MAN and WAN.
- How does the
Internet model differ from the OSI model? What are the layer differences?
- Know what each
layer of the Internet model is responsible for. What are the functions and how
do they communicate with the other layers.
- Define a protocol
and give some examples of protocols used at each layer, e.g. Twisted Pair,
Ethernet, IP, TCP, HTTP.
- What is the
difference between de facto standards and official (de juro) standards and
explain why standards are important in Networking.
- Know these
Standards making groups: ANSI, ISO, ITU-T, IEEE
Chapter 2 -
Application Layer
- Define Application Architecture
- Define a cluster.
- What is tiered architecture? Describe
different levels and the advantages/disadvantages of each (think in terms of
cost, complexity and scalability)
- What is middleware.
- What is a thin client versus a fat or
thick client?
- What is a client/server architecture?
What are the pro's and con's of it versus a Host based and also a PC based
architecture?
- Define URL. How is it different from just a web address?
- What is the main difference between
SMTP, POP(3) and IMAP email protocols?
Chapter 3 -
Physical Layer
- Give some physical
layer protocols.
- Understand the
difference between analog and digital data.
- What is the
difference between point to point and multipoint (shared) circuits?
- What is simplex
transmission versus half and full duplex?
- Pros and Cons of
using Fiber Optic cable versus twisted pair or Coax
- Define Propagation
Delay and understand why it is an issue with Satellite Transmission.
- Know the important
factors in choosing media
- What is wave
amplitude versus frequency? What are all the properties of a wave?
- Define Modulation
- What is DSL and
how is it similar and different from Cable Modem service. What layer are these protocols found?
Chapter 4 -
Data Link Layer
- What is Media
Access control and on what are its responsibilities?
- What is the
difference between contention based and token passing and polled access
control?
- Which is better
for large networks? Contention Based or Controlled approach?
- Which types of
media are more/less susceptible to noise?
- What is the
primary source of errors on data networks at this layer?
- Define
Attenuation.
- Understand what
error checking and error correcting is. (ACKs and NAKs)
Chapter 5 -
Transport and Network Layer
- What is the
difference between the Transport and Network Layers?
- What is TCP/IP?
What does the TCP part do? What does the IP part do? Who invented it?
- How are port
address used to link the transport/network layer to the application layer. Give
some standard port addresses for commonly used applications.
- What is the
difference between IPv4 and IPv6 and why was IPv6 invented?
- What is a Netmask?
What is a Class A, B and C subnet network?
- What is the
difference between Unicast, Broadcast and Multicast?
POSSIBLE
ESSAY QUESTIONS:
·
