In Detail

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.
