Learn everything about Internet – Ethernet, IP, Routing, Switching, TCP, UDP, NAT, DHCP and DNS, prepare for CCNA exam
Instructed by Bogdan Stashchuk 14.5 hours on-demand video & 2 articles

What you’ll learn

  • How Computer Network operates on different layers of the What are TCP/IP and OSI model
  • Logical and hardware addressing of the devices (IP addresses and MAC addresses)
  • IP addressing, Network masks, Subnets and Subnetting
  • How Switches perform switching decisions and build MAC address tables
  • How Routers build routing tables and which type of routes exist and how routers utilise Routing tables to route packets
  • How packets are transferred end-to-end via Switches, Routers and how network headers (Ethernet and IP) change during this transmission
  • Understand purpose and differences of the TCP and UDP protocols
  • Learn how DNS registry is built and which types of the DNS Nameservers exists and what are their responsibilities
  • Learn difference between private and public IP addresses, concerns related to them and need for NAT – Network Address Translation
  • Understand differences between link-state and distance-vector routing protocols and learn what is BGP – core routing protocol in the Internet

In practice sections you will perform multiple practice Networking activities:

  1. Install Wireshark and use it for analysis of the networking protocols
  2. Analyse Ethernet headers
