CIS-165, Introduction to Data Communications

Credits: 3

Course Description

CIS-165, Introduction to Data Communication, is the first course in data communications and networking. It provides a comprehensive introduction to the fundamentals of data transmission, focusing on the lower layers of the OSI model. Broad overview of data transmission concepts such as signaling, encoding, modulation, and error detection are explored. Topics relating to network security including cryptography, message Security, user Authentication, and key management are introduced. Prerequisite: CIS-139 or permission of the program advisor. Three hours lecture each week. Three credits. Three billable hours.

Course Objectives and Grading Information

MAJOR COURSE OBJECTIVES:  Upon completing this course the student should be able to: 

1. Describe the role of OSI/Internet models with respect to various protocols and standards in data communications GE2, PG2. Create web pages that will retrieve and display information from a web server database. (GE1, PG5) 

2. Clearly explain the characteristics of analog and digital signals: time vs. frequency domain, BW, Nyquist bit rate, Shannon capacity, bandwidth-delay product.GE2, PG2. Create web pages that update and delete database records. (GE1, PG5) 

3. Compare and contrast the analog transmission mechanisms to digital transmission. Explain analog-to-digital and digital-to-analog (ASK, PSK, FSK, QAM) conversion process. Become familiar with various line and block coding techniques.GE2, PG2. Create web pages that validate user data before sending the data to the web server. (GE2, PG5) 

4. Discuss bandwidth utilization techniques: multiplexing (FDM, WDM, TDM, STDM) and spread spectrum (FHSS). (GE2, PG5) 

5. Compare and contrast the characteristics of various transmission media. (GE2, GE3, PG5) 

6. Compare and contrast circuit switching with packet switching networks. (GE2, GE3, PG5) 

7. Explain various error detection and correction mechanisms: block coding, linear block codes, cyclic codes, and checksum. (GE1, PG5) 

8. Describe data link control protocols along with multiple access protocols and Ethernet LAN?s. (GE1, GE3, PG5) 

9. Discuss various topics related to security and cryptography: symmetric/asymmetric (RSA, Diffie-Hellman) key cryptography, digital signature, message confidentiality/integrity and digital signatures. (GE1, GE3, PG5)
