Protocols
• Communication Hardware
• Communication Software
• Network Theory
• Network Hardware
• Network Application: Peer-to-Peer
Networking and Wireless Networking
• Internet/WWW Infrastructure
• Network Security
Coverage
• Theory will mostly be covered during
the first half of the quarter that would
include coverage on TCP/IP
• The second half of the quarter will
partly focus on hands-on exercises
Students’ Perspective
• Learn the basic theory of computer
communications
• Become familiar with communication and
networking technologies such as, for instance,
packet switching and circuit switching
• Obtain a good understanding of TCP/IP, the
primary transport and internetworking
protocol of the Internet
Students’ Perspective
• Become aware of communication software
such as FTP and Hyper Terminal
• Acquire some experience in multimedia
streaming over the Internet
• Have a good understanding of the functional
network architectures such as the peer-topeer, client-server and thin-client network
architectures
• Have a grasp of the physical network
architectures such as the bus, ring and star
architectures
Students’ Perspective
• Become aware of the basic hardware
and software used in building networks
• Be exposed to a number of topics
covered under different sections of the
Microsoft certification examination
• Be able to set up a peer-to-peer network
and understand the concept of sharing
resources on the network
Students’ Perspective
• Have acquired the knowledge to set up a
simple network and connect the network to
the Internet using a broadband
connection such as DSL
• Have a good working knowledge of the
Internet infrastructure from a communication
point of view
• Be introduced to issues related to network
security and possible security safeguards that
may be pursued
Delivery of Instruction
• Based on Technology Mediate Learning
(TML)
• TML Components
– Website
– Multimedia CD-ROM
– A probable Cyber-lab accessible from any
computer on the Internet
Website Addresses
• Address for internal/external access:
– www.calstatela.edu/faculty/nganesa
• Address for internal access:
– ganesan.calstatela.edu
Multimedia Modules
• Students may be required to listen to
multimedia modules during regular lecture
hours
• Students are therefore required to bring their
own set of headphones for each class
• Leaving the headphones at home is
equivalent to being absent from part of a
lecture
TML Advantage
• The in-class meeting may be reduced by
a certain percentage of time thus
enabling the students to take full
advantage of Technology Mediated
Learning (TML)
– As permitted by university guidelines
Attendance
• Regular attendance at this stage is
emphasized
• Course material
– Reflect new developments
• Missed class meetings
– Copy the notes from a friend
References
• Website listed
• Course slides stored under Lecture
Notes on the web
• Stored references
– A collection of web references stored in
PDF format
– A listing of relevant web links
Textbook
• Refer to the web

Project Groups
• One group project is required
• Each group would be composed of 4
members
• The end result would be a project
presentation and a project report
Project Task
• Projects can be exploratory in nature or they
could deal with an actual implementation of
hardware and/or software relating to
communications
• Projects that explore the actual
implementation of hardware and software
will be graded favorably
• Selection of topics that are purely theoretical
in nature and those that deal mostly with
management issues are discouraged
• Sample topics will be discussed later
Project Topic
• Must be application oriented
• Two choices for possible project topics
– Review an actual implementation
– Give a hands-on demonstration of the
features of a hardware/software system
relating to communications
Anchor Areas for Project Topics
• Internet communications
• Web related communications
– Audio and video streaming
• Internet security
– Encryption, VPN etc.
• Emerging platforms
– .Net
– J2EE
• Other contemporary and emerging areas of
communications
Experience Related Topics
• With the approval of the instructor, a student
may embark on an individual project in lieu
of the group project
• Students having extensive experience in
communications or those who are involved in
communication related projects are
candidates for individual projects
• Anyone fulfilling the above requirements
may consult with the instructor for discussion
and approval of a project topic
Job Related Topics
• A student may also be allowed to present
current job related information as an
individual project provided the current job
relates to either communications or
networking
• Again, anyone wishing to pursue a job
related project topic may consult with the
instructor for discussion and approval of a
the topic
A Note of Caution
• Do not present the material covered or
that is slated for coverage in the class as
part of the project presentation
Project Methodology

topic
• Step 2a: For the exploratory projects, describe
the actual implementation of a system or
describe a specific feature of a software in the
area of communications
• Step 2b: For the hands-on projects, give a
demonstration of chosen hardware and/or
software chosen for the project
Project Presentation

Course Material
Module Objective
• Text Book
• Student Guide
• Link to Microsoft Certification
Examination
• Other Recommended Books
• Electronic Reference
• Software
Text Book
• Business Data Communications by Raymond
R Panko
• The strength of the book lies in its application
oriented treatment of the subject
• To a large extent, the book covers the subject
from a networking and an Internet point of
view thus enhancing its usefulness
Overview of the Textbook
• Many of the topics and information covered
in this course are also covered in the book
• The book is recommended for those who find
the subject covered in the student guide
difficult to follow
• The application portion of the course such as
the peer-to-peer networking etc. are,
however, not covered in the course
The Role of the Text Book
• Because of the fact that the multimedia
modules of the course are based on the
student guide, the text book plays a
complimentary role
• Therefore, the text book is discussed
form this vantage point
Text Book Coverage
• A good source for backup information on
theoretical topics
• Computer networking is better covered in the
student guide
• Internet topics are covered more extensively
in the text book
• The author also maintains a web address for
supporting course material such as display
slides etc.
Text Book Usefulness
• Students with minimal exposure to the topics
to be covered and those who have difficulty
following the concepts are most likely to
benefit from the book
• Others may opt to use the book as a reference
• In essence, the book is best used as a
reference, in particular, for Internet related
topics
Overview of the Student Guide
• A student guide containing the slides to
be presented in the class is required
• It can be purchased from the instructor
at a cost of $25.00.
• Please enlist your name for the
purchase of the student guide
immediately after the end of the first
class meeting
Student Guide Contents
• The student guide will be the primary
course material
• The guide is divided into four parts
– Communication Theory
– Communication Hardware, Software and
Services
– Local Area Networks
– The Internet
The Role of the Student Guide
• Because the course will be taught
electronically for most part, the student
guide is required as the base material
for the multimedia modules
• Most of the slides that are displayed can
be found in the student guide except, of
course, the software demonstrations
Other Recommended Books for
Further Study
• FrontPage 98, Paperback Edition
• Networking Essentials, published by
Microsoft Press
• Windows 95 and Networking Essentials
by Casad, published by New Riders
• Contact Microsoft at its web site
www.microsoft.com for further details
on available FrontPage 98 books
Summary of Hardcopy Reference
• Required text
– Ganesan, Nanda, Local Area Networks, 1997
– Business Data Communications, Raynond R.
Panko
• Additional reference
– Person, Using Windows 95 Special Edition, Que
Corporation, 1995
– FrontPage 98, Paperback edition.
Electronic Reference
• All the electronic references discussed earlier
in relation to the class project apply equally
well to the entire course as reference material
• In particular, the online reference named
Datapro can be specially useful in
understanding the concepts
• Datapro is essentially an encyclopedia of
computer terminology and technology
Software
• Hands-on experience with Windows95
is required
• Knowledge of FrontPage 98 will be
acquired during the course
