Instructor: Contact: Office: Office hours:
Description This course provides an introduction to data communications and networking technologies. Topics covered include fundamentals of networks, OSI model, networking protocols, signaling, cables, connectors and networking devices. It will also cover multiplexing, circuit and packet switching, IP configuration, network design, switching, routing, firewalls, network security and port configuration. This course prepares students to pass the CompTIA Network+ exam.
Instructional Objectives:
- Introduce networking concepts and fundamentals of topologies.
- Familiarize students with client server and peer-to-peer networks.
- Introduce the OSI model and functions of each layer, network signaling and protocols.
- Familiarize students with TCP/IP models and addressing schemes.
- Familiarize students with network cables, connectors and networking devices.
- Introduce students to the properties and purpose of the Ethernet, IP configuration and wireless networking.
- Provide students with knowledge of WAN transmission, switching and routing.
- Introduce students to network security fundamentals and management.
- Familiarize students with troubleshooting and problem solving in a real-world environment.

The student cannot set up the experiment correctly.
The student can set up the physical environment for the experiment but cannot execute it.
The student sets up the experiment correctly but configures it incorrectly.
The student sets up the experiment well, runs it well, but does not comprehend the results and cannot relate the meaning of what he or she has accomplished. Essentially, they followed the recipe but show a lack of understanding.
The student successfully sets up and runs the experiment, documents his or her results and shows a clear understanding of the process.
