About this course

Skip About this course

As computer systems become smaller, cheaper, and more readily accessible, it seems everyone is connected at the touch of a button. Organizations struggle to remain efficient as they manage growing numbers of single-user computer systems. These systems require interconnectivity to exchange data, share resources, and access more powerful computers for tasks too complicated for local computers to process.

All of these activities require computing devices to access multiple networks. This course introduces networks such as the local area network (LAN), the enterprise network, the campus area network (CAN), the metropolitan area network (MAN), metro Ethernet, the personal area network (PAN), the virtual private network (VPN), and the wide area network (WAN).
The course discusses the essentials for implementing modern computer networks. Each lesson goes through the various networking technologies. The course introduces the concepts and practices associated with network security vulnerabilities, threats, risk mitigation, and the policies and procedures associated with security management.
