ECET 375 Week 1 iLab Exploring Internet
Standards, RS-232 Communication, and
Connectors
Objectives:

During lab we explored Internet RFCs, RS-232
Communication data format and Cables and
Connectors
Results:
This lab was basically a research project to help us
understand how the Internet Standards are
created and how to pick the correct interface
material that meets the requirements of any
interface. Some of the topics were also refresher
information from other ECET classes like the ASCII
wave forms.
Conclusions:
After you design a system it’s critical to use the
correct interface mediums and material types that
meet your requirements. Picking materials that
cover data rate or frequency values beyond your
requirement will have an adverse cost effect on
your final design. Keeping up with technology and
standards is important in engineering. Before you
pick materials for your design, complete your
research to insure you take advantage of
standards and material types that meet your
requirements but do not exceed them. Balance the
quality of these materials with your projects
budget and you’ll be successful.

DEVRY ECET 375 Week 2 iLab Calculating
Spectrum and Linear Filtering in MatLab NEW
devry/ecet-375-week-2-ilab-calculating-
spectrum-and-linear-filtering-in-matlab-
recent
Objectives
This lab is intended to explore signal spectrums
and filtering operations using MatLab. Running
pre-written MatLab scripts and altering these
codes to perform specific tasks will be necessary
to develop the appropriate displays. Calculation of
a signal spectrum using the SigSpec.m file, and
altering this file to display different types of
signals including Cosine, AM, and Square waves
will help to explore signal characteristics and
display MatLab functionality. Using a second per-

written file (LinFiltering.m) and MatLab,
displaying how filtering can affect a signal, will be
used to describe this process and how the
resulting signal changes.
Results
During the exploration of this lab, the MatLab
program was used to run specific functions
containing the code necessary for appropriate
signal plotting. These plots were created for the
cosine, the AM, the square wave, using random
information and breaking down a sound file
(.wav). For each of these signals a MatLab plot was
acquired, and used for analysis. Additionally,
running the LinFiltering.m file in MatLab allowed
the explanation of filtering to be shown in a plot.
These plots were created for both the time and
frequency domain, and successfully showed how a
filter can help contain a signal.
Conclusions
After the completion of this lab, the concepts
included are starting to make more sense.
Realizing how powerful MatLab can be, and the
functions accomplished by it are astounding.
Creating the signal plots, being able to visually see
the intended signals and then manipulating these
signals is a real asset in the learning process. Each
signal has its own characteristics and these

characterstics can be contained, soften the edges,
by using different filtering techniques. These
filters can help remove unneeded data, showing
the true signal behind it.

Protocol Hierarchy and the Ethernet Layer NEW

Objective:
In this lab, you will explore
a)Internet Protocol Hierarchy
b)ARP protocol and Ethernet Layer operation
Required Equipment:
A PC with Wireshark program installed
Following file: ecet-375WebBrowsing.pcap
Observations:
The captured data was analyzed using Wireshark.
This data was compiled into lists and used to

populate data tables.
Conclusion:
The information and techniques are well
documented. The lab went as well as expected. The
Wireshark program leaves off the SFD and FCS
from the packet data, otherwise everything went
well and as expected.

Objectives: This lab was the exploration of the
DHCP protocol operation and the IP protocol
operation using Wireshark and two .PCAP
captured files.
Results: The results showed that the DHCP was
easy to follow in how it configured the client for a
temporary IP address, along with a lease time, and
also provided header information. The IP protocol
provided details of messages sent such as
fragment information and how many bytes per
fragment.
Conclusions:. Wireshark is designed in such a way

that makes following the messages and server
feedback readable and easy for troubleshooting.
Although we did no troubleshooting in this lab, the
concept is observable as we studied the details of
each packet

Protocol Hierarchy and Ethernet Layers NEW
internet-protocol-hierarchy-and-ethernet-
layers-recent
Objectives
The purpose of these lab procedures is to visually
see how the Ping and Traceroute Applications
work. This will be done using WireShark and a
precaptured file “ecet-
375RemotePingTracert.pcap”. The use of IP and
ICMP protocols in diagnostic testing will be
accomplished by writing the command in the DOS
Prompt and captured in the WireShark program
(already done for us). This file will be analyzed,
depicting which packets do what and the time
taken between specific packets.

Results
During the exploration of this lab, the WireShark
program was used to analyze a pre-captured
internet session. Examining the “Ping”
ofwww.iana.org is the basis of the first procedure.
Determining which packets are DNS query’s and
which packets are DNS responses as well as the
actual IP address for this link is accomplished in
the first few steps. With the ICMP protocol,
knowing that there are four requests and four
echo responses, these packets are found and
documented. Additionally, the times between
request and reply are found and recorded with the
help of the “Set Time Reference (Toggle)” within
the WireShark program.
The next procedure, Traceroute, also deals with a
Dos command of “tracert” and is done on the same
address of www.iana.org . The packets that take
care of the DNS query for an IP address for the site
are discovered and documented, as well as the
number of HOPs performed on the investigated
trace. Similar to the “Ping” procedure, the time
between the requests and the error responses are
discovered using the “Set Time Reference
(Toggle)” with 3 requests and responses per HOP.
Conclusions
After completing this lab and seeing how these

investigative tools can help in the diagnostic of a
communication network, it is realized the
importance of applications like these. In my
profession I have used the “PING” command to see
if a specific computer in the domain is “alive” and
communicating. The Traceroute command is new
and can be just as useful. Using the Traceroute
application to ensure communications through all
routers and switches is occurring and in a timely
fashion can prove to be very useful in discovering
issues to come.

ECET 375 Week 7 Homework NEW

DEVRY ECET 375 Week 7 iLab Exploring TCP_UDP
Communication in the Internet NEW
tcp_udp-communication-in-the-internet-
recent
Discussion:
TCP (Transport Control Protocol) and UDP (User
Datagram Protocol) operate at the Transport layer
of the Internet Protocol Hierarchy. They deliver
information between Internet applications. To
identify the applications running on a host,
Internet transport layer uses port numbers, each a
sixteen-bit number expressed as a decimal
number (e.g. 80). Each host interface on the
Internet is uniquely identified by an IP address, a

32-bit number usually expressed in dotted
decimal notation (e.g.192.168.1.45). TCP and UDP
combine data from multiple applications into a
single outgoing connection at a source host. This
process is called multiplexing. These protocols, at
a destination host, separate data arriving at an
incoming connection destined for different
applications. This process is called demultiplexing.
TCP is connection oriented and has many other
features geared towards providing reliable
communication, flow control and congestion
control. UDP is connectionless and does not have
these features.
In this lab, you will analyze pre-captured
Wireshark files to explore features of TCP and UDP
protocols and their differences.
