Delivery Method

This course will be delivered online in an asynchronous (non-real-time) format using Blackboard. The course is done in an independent study format.

CMP 405 Course Description: 4 hours, 3 credits

Introduction to network protocols and algorithms. Intensive study of the most important protocols at each layer. Examination of their strengths and weaknesses. Basic algorithms for identifying primary servers, constructing forwarding and broadcasting trees, and determining routing tables. Writing a simple networking service at the I.P. layer or higher. Lab exercises include building and testing small networks.

Prerequisite:

• CMP 334 - Computer Organization
• CMP 338 - Data Structures and Algorithms

CMP 743 Course Description: 4 hours, 4 credits

Digital and analog communication, system architectures, and connection-oriented and connectionless service. The OSI model as a conceptual framework, and actual communication models and their protocols. Selected contemporary topics, such as communications security and the World Wide Web.

Prerequisite for CMP 743:

• A course in operating systems.

Course Objectives

At the end of the course, students should be able to:

1. Define and use basic concepts and terminologies for networking.
2. Describe the layers of the TCP/IP reference model and their purposes.
3. Work with classful and classless internet addressing.
4. Explain the Address Resolution Protocol.
5. Identify the elements of segments, datagrams and Ethernet frames.
