About Course

Welcome to the third of five courses in the Cisco Networking Basics Specialization. Now that you know the basics of what an network is and how the devices on a network communicate with each other, it is time to explore the network further. In this course, you will learn the benefits and limitations of the IPv4 addressing system and why NAT and IPv6 were implemented to address the limitations. You will also explore common network services and protocols such as email, web services, instant messaging, DNS, HTTP, HTML, SMTP, Telnet, and SSH. At the end of this course, you will be able to: 1. Describe the role of network services including DHCP and DNS. 2. Use Cisco Packet Tracer to configure a router to perform DHCP services for a LAN. 3. Explain use of IPv4 private addresses with NAT. 4. Compare TCP and UDP protocol operations for efficiency and reliability. 5. Describe the network services and applications for file transfer, web access, email, remote access and instant messaging. 6. Observe how web requests are processed by the web client and the server. 7. Use various tools to verify network operations.

Course Syllabus

In this module, you will learn the purpose and benefits of using static and dynamic addressing in a network. You will use Packet Tracer to create a small wired network and enable the devices to automatically obtain the needed addressing information to connect to the network.

Next Generation Data Communications Initially, data communications will be an additional means for two-way exchange between controllers and flight crews for air traffic control clearances, instructions, advisories, flight crew requests and reports. Eventually, the majority of communications will be handled by data communications for appropriately equipped ground and airborne stations. Data communications will enable air traffic control to issue an entire route of a flight with a single data transmission directly to the aircraft's flight management system.
Next Generation Data Communications Adding air-to-ground and ground-to-ground data communications will significantly reduce controller-to-pilot communications and controller workload. The data communications will enable ground automated message generation and receipt, message routing and transmission, and direct communications with aircraft avionics.
