CompTIA Network+ (N10-008) Cert Prep: 3 The World of TCP/IP

This series prepares you for the CompTIA Network+ (N10-008) exam, one of the most important entry-level certifications in the IT industry. In part three of this series, instructors Mike Meyers and Joe Ramm go over what you need to know about TCP/IP. First, they introduce you to IP addressing, ARP, and basic subnet masks. Then they explain how to recognize the various classes of IP addresses, as well as how to use CIDR notation to segment subnets even further. Mike and Joe show you the differences between dynamic and static IP addressing and discuss some special IP addresses. They cover routing, with topics including ports, network address translation (NAT), SOHO routers, static and dynamic routes, RIP, and more. Plus, Mike and Joe walk you through OSPF (a link-state protocol) and BGP (which lets ISPs communicate with each other).
