CompTIA Network+ 2012: Networking Concepts Part 1

This course is included in our On-demand training solution.


Networks are the basic interconnections for all computers from home computer systems to multinational businesses to the Internet. In order to understand how networks function, you need to start at the beginning and learn the fundamental building blocks of networks and how data travels from one point to another. This course introduces the basic concepts of networking, including network models, such as the OSI model and the TCP/IP model and the protocols and applications that function within these models. This course also explains the basics of routing and switching operations. This course prepares the learner for the CompTIA Network+ 2012 certification exam N10-005. Network+ is sometimes referred to as N+ or Net+.

Target Audience

The audience for CompTIA Network+ 2012 training will comprise IT personnel with at least nine to 12 months of IT networking experience. Good computer literacy along with a sound technical acumen should be present. This learning path is also suitable for students looking to acquire job skills, and to be trained specifically to pass the associated CompTIA Network+ (2012 Edition) certification exam. It is recommended, but not required, that candidates for the CompTIA Network+ 2012 exam obtain the CompTIA A+ certification or equivalent knowledge.
