  3. Networking Fundamentals
Summary

  • Comprehensive overview of the principles and standards for modern data networking, include all layers ot the TCP/IP protocol, including fiber optics, WiFi, Ethernet, VLANs, switching, routing, TCP, UDP, HTTP, SSH, IPv6, and all related layer technologies and common network management tools.

Description

In this course, we will take a broad look at the fundamentals of networking, with an emphasis on TCP/IP (the Internet protocol suite). The course will: 1. Introduce the architecture and typical mechanisms of the Internet, review the TCP/IP protocol layers, discuss the IETF, compare TCP/IP with the OSI model, and relate encapsulation to protocol layers 2. Survey the Physical Layer, focusing on Ethernet over copper and fiber cables, and the physical aspects of WiFi. 3. Discuss the Data Link Layer, including Ethernet frames and local networking, switching, VLANs, and the data link aspects of WiFi. 4. Examine the Network Layer, including the details of IP, as well as ARP/RARP, net masks and subnets, routing, DHCP, multihoming, NAT, non-routable addresses, multicast, and ICMP. 5. Discuss the Transport Layer, including UDP, TCP, hostnames and the hosts file, DNS, and TLS/SSL. 6. Review the Application Layer, including Web Pages (HTTP and HTTPS), Remote Login (SSH, TELNET), File Transfer (FTP, SFTP), and Network Management (SNMP). 7. Discuss useful tools for managing and troubleshooting networks, including ping, traceroute, ipconfig, tcpdump, whois, netstat, speedtest, subnet calculators, IP scanners, and WiFi troubleshooting 8. Discuss examples of devices, services, and typical network operations. 9. Briefly discuss IPv6, how it compares with IPv4, and future prospects. At the end of each lesson, there will be quiz. You must pass all quizzes and view all tutorials to pass the course. The course is interactive and self paced. An Internet connection and current browser are required.
