Building on the material of Computers and Networking 1, this second course in Computers and Networking examines networking in greater depth. LAN switching, IPv4 addressing, subnetting and routing allows an understanding of both LAN and WAN technologies. Applications of these principles include Industrial Ethernet, Comercial networks and Medical networking. Also wireless networks and protocols including WiFi, Bluetooth, and ZigBee are explored. The Raspberry Pi single board computer will be networked to demonstrate the principles of the Internet of Things (IoT) concept. The topics of Cisco's CCENT certification are covered within Computer and Networking Courses 1 & 2.
