• 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-to-peer, 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

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

MODULE VII
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
