Video description

Do you want to learn the basics and advanced concepts of computer networking? Do you want to prepare for the Cisco Certified Network Associate (CCNA) exam? With this course, you will learn the basic and advanced concepts of computer networking from scratch.

The course starts with Transmission Control Protocol/Internet Protocol (TCP/IP) and Open Systems Interconnection (OSI) models, explaining how different hosts communicate with each other. Next, you will become familiar with networking layers, such as physical, data link, network, transport, and application. Once you have gained the knowledge of layers, you will move towards exploring the concepts of routing and learn the difference between private and public IP addresses. Next, you will discover the purpose of Network Address Translation (NAT) in networking and understand the Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) protocols in detail.

By the end of this course, you will have gained a solid understanding of computer networking and network devices and will have developed the skills to pass the Cisco Certified Network Associate (CCNA) exam.

What You Will Learn

  • Use routers to build routing tables to route packets
  • Distinguish between private and public Internet Protocol (IP) addresses
  • Build Media Access Control (MAC) address tables using switches
  • Analyze Address Resolution Protocol (ARP) requests and responses using Wireshark
  • Grasp techniques for building a Domain Name System (DNS) registry
  • Become familiar with the Border Gateway Protocol (BGP) global routing protocol

Audience

Whether you are a computer network professional, software developer, or DevOps engineer, who wants to build a strong foundation in computer networking and network devices, this course is for you. Those who want to prepare for the Cisco Certified Network Associate (CCNA) exam will also find this course useful. There is no prerequisite to get started with this course.
