Introduction to Networks is the first of 3 courses in the Cisco Certified Network Associate (CCNA) curriculum. This course introduces the architecture, structure, functions, components, and models of the internet and other computer networks. The principles and structure of Internet Protocol (IP) addressing and the fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the curriculum. By the end of the course, students will be able to build simple local area networks (LANs), perform basic configurations for routers and switches, and implement IP addressing schemes.
Explore and describe the devices and services used to support communications in data networks and the Internet.
Use Cisco command-line interface (CLI) commands to perform basic switch and end devices configurations.
Describe the role of protocol layers in data networks.
Explain fundamental Ethernet concepts, such as media, services and operations.
Describe the functions of the network layer and the importance of addressing in IPv4 and IPv6 environments.
Design, calculate and apply subnet masks and addresses to fulfill given requirements in IPv4 and IPv6 networks.
Explain the operation of application and transport layers protocols.
Build a simple network using routers and switches.
