COMN-120 Network EssentialsCredits 3 / 3 Contact Hours Pre-requisite: Placement into ACRD 080 . Pre- or Co-requisite: COMG-153. Note: Student must provide own personal storage device. This course is designed to give students a broad overview of current terminology and technologies found in current networking environments. Topics include local and wide area networking, the OSI model, TCP/IP and network protocols, media architecture, and networking hardware. Network designs using various topologies and protocols as well as the basic concepts and approaches involved in maintaining and administering a network will also be addressed. This course will also help to prepare students for the CompTIA Network+ exam.
