CompTIA Network+ 2009: Network Fundamentals

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

Overview

The physical and logical ‘shape’ of a network is called the topology. Topologies have a great deal to do with how a network communicates and even what devices and media can be used on the network. As well, the scope of a network, for example, if it’s a LAN, MAN, or WAN, can have an impact on the type of topology chosen for implementation on the network. This course covers the basic devices used in a network, such as servers, workstations, and hosts, and focuses on the different logical and physical topologies that networks can be based on. The course explores network architectures, including Ethernet, broadband, and XBasex technologies, and also examines access methods such as CSMA/CD and broadcast. In addition, the various scopes that can have a bearing on the type of topology put into operation are explained. This course maps to the CompTIA Network+ 2009 exam objectives for identifying physical and logical topologies, and categorizing LAN technology types and properties.

Target Audience

The audience for CompTIA Network+ 2009 training will comprise IT personnel with at least 9 months IT networking experience. Good computer literacy along with a sound technical acumen should be present. Students looking to acquire job skills, and to be trained specifically to pass the associated CompTIA Network+ (2009 Edition) certification exam will want to study this learning path.

Prerequisites

CompTIA’s A+ credential is a recommended, although not mandatory, prerequisite.

Expected Duration

120 min.
