computer and network systems administration (CNSA)
CNSA 107 (3 Credits)
PC Hardware and Support Fundamentals

This course is focused on the internal components and
operation of digital devices with emphasis on desktop PC
systems used for business. Processors, memory, hard
drives, SSDs, communication buses, and other components
are covered. Electricity fundamentals and the binary
numbering system are also a part of this course. Students
build a computer from scratch in the lab.

CNSA 111 (3 Credits)
Introduction to Networking

Provides an overview of modern networking arrangements
and goes into detail about the digitization of analog signals,
the OSI model, the Ethernet protocol, and Ethernet switching.
IP addresses and IP sub-netting are also covered in depth.
Prerequisite: CNSA 107

CNSA 117 (3 Credits)
Analysis of TCP/IP and Local Area Networking

The TCP/IP protocol suite is explored in detail. Topics include
ARP, ICMP, DNS, DHCP, IPv4, IPv6, and TCP operation details
such as sequencing, acknowledgments, and sliding window
flow control. After lecture is complete, students spend lab
time capturing frames with a software protocol analyzer
and verifying the behaviors they learned about in lecture.
Wireless networking (WiFi) is also a part of this course.
Prerequisite: CNSA 111

CNSA 123 (3 Credits)
LAN Cabling and WAN Technologies

Cabling standards and best cabling practices in the industry
are covered. Students practice hands-on cable termination
of copper and fiber cables in the lab. This course also
provides an overview of telecommunications technologies
and the use of telecommunications in wide area networks
(WANs).
Prerequisite: CNSA 117

CNSA 156 (3 Credits)
Operating Systems I

Microsoft's server operating systems are a dominant
network operating system in the information technology
industry. In this course, along with CNSA 161, students
get detailed lecture about and hands-on experience with
Microsoft's server operating system. Practical handson experience is included in the labs and begins with
attended and unattended installation methods. Included in
installation methods are imaging and cloning techniques for
mass rollouts of server and client operating systems. The
lecture and labs continue with configuration of file and print
servers, securing files with share and NTFS permissions,
disk management (including RAID), disaster recovery, and
backup methods.
Prerequisite: CNSA 123

40 * Thaddeus Stevens College of Technology

CNSA 161 (3 Credits)
Systems Administration I

This course continues where CNSA 156 leaves off. In this
course, students learn about Microsoft's Active Directory
structure and management. User account maintenance,
user profiles, logon scripts and group policy are covered.
Students also learn in the classroom what goes on behind
the scenes with dynamic host control protocol (DHCP or
automatic addressing) and domain name server (DNS or
computer name resolution). Ultimately, students take this
classroom theory and apply it in the lab as they create their
own active directory domains and configure DHCP and DNS
services within their domain.
Prerequisite: CNSA 156

CNSA 166 (3 Credits)
Internetworking Devices and Concepts

This is a Cisco-centric course on IP routing and switching.
Traditional routers and L3 switches are discussed in the
classroom and used in the lab. Routing protocols such
as RIPv2, EIGRP, and OSPF are covered. In addition to
routing, voice-over IP (VoIP) is a significant technology
that businesses implement in order to reduce cost and
leverage investments in the data network. For that reason,
this course provides an overview of VoIP and assigns a lab
project to configure a software private branch exchange
(PBX) telephone switch that is capable of routing phone
calls within the lab environment.
Prerequisite: CNSA 161

CNSA 172 (3 Credits)
Web Technologies and Network Security
Fundamentals

Students learn how to configure a web server that can host
multiple websites. The course then moves into the creation
of web pages from scratch using HTML, CSS, and a text
editor. Since security has become an increasingly important
issue in our times, some of the security measures that are
commonly used on the Internet are included in this course.
These security measures include an overview of threats and
defense strategies, the public key infrastructure (PKI), digital
certificates, hash codes, and digital signatures.
Prerequisite: CNSA 166

CNSA 212 (3 Credits)
Programming I

An introduction to the fundamentals of computer
programming. Students learn a structured, object-oriented
approach to problem solving and automating routine
processes using modern programming languages. The
programming concepts used emphasize logical thinking and
current programming standards and conventions. Students
learn to plan, design, compile, debug, and document
applications in a visual programming environment using a
programming language that is compatible with the Microsoft
.NET Framework. In addition, the course introduces the
integration of programming applications with databases as
well as next generation programming environments.
Prerequisites: CNSA 156 and CNSA 161
