CompTIA Network+ 2009: Network Devices

Overview/Description

Some devices, such as routers and switches, will be found on almost every network, while other devices, such as wireless access points and content switches, are more specialized and will only be present if the needs of the network mandate them. This course describes network devices from the user level, which includes network interface cards, firewalls, and modems, to network level devices, such as routers, switches, and bridges. It also explains the logical operation of these devices and introduces some of the more specialized hardware and software that might be found in networks. This course maps to CompTIA's Network+ (2009) exam objectives for installing, configuring, and differentiating between common network devices. It also covers identifying the functions of specialized network devices and explaining the advanced features of a switch.

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.
