N+ Network

Students will learn the skills and knowledge to help prepare them to take the CompTIA Network+ certification exam.

Prerequisites
None; however, the certification exam is targeted for computer technicians with 18 to 24 months in the IT field. A+ certification or equivalent knowledge is also recommended.

Objectives
Lesson objectives help students become comfortable with the course, and also provide a means to evaluate learning. Upon successful completion of this course, students will be able to:
• Describe the purpose of networking protocols and networking in general.
• Identify features of various network operating systems and the clients used to access them.
• Describe the OSI networking model and its relationship to networking components.
• Describe the network components relating to the Physical layer of the OSI model.
• Describe the function of the Data Link layer of the OSI model.
• Explain how data is transmitted over a network.
• Describe the function of the Network layer of the OSI model.
• Describe the function of the Transport layer of the OSI model.
• Describe the function of the Session layer of the OSI model.
• Explain the fundamental concepts of the TCP/IP protocol suite.
• Explain the use of TCP/IP addresses and subnets.
• Access and use a TCP/IP network.
• Describe the requirements for remote network access.
• Explain the need for and ways to implement network security and fault tolerance.
• Describe the types of information that need to be gathered prior to installing or updating a network operating system.
• Explain ways to monitor and manage a network.
• Describe a systematic approach for troubleshooting network problems.
