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....

This course is really worth learning simulation of the OSI layer and viewing bit by bit transmission of data of each layer. We can also learn the basics of Mail and data transfer protocols.

Really Well paced course. The quiz content was sometimes not related to the module therefore I have not given the highest rating

Very easy to follow. Succinct and relevant examples make it easy to pick up new concepts and apply them to real-life scenarios

Good mix of content. Most important topics are discussed. Very few Lab activities and practical experiences.

It's not well organized and have lots of issues like course 1 and 2 The exam was at the first week instead of week 4 !!!!Some practices have wrong answers and make the student to answer them incorrectly .The course although has variety of information that's a good pointI have had these courses before and I just enrolled because of practice and review but if someone who hasn't this course before will be extremely confused.sorry for my bad English.

Course is more or less fine- not enough information provided, also provided with some misconceptions and misleading information though, look like it was created in a haste. The assessment mechanism is the most crappiest ever, though as many other on this Coursera site.

I work as a network engineer, evaluating products for my team. As long as you have peer review, you CAN NOT PASS! Students who don't understand the subject matter, or questionably know your language, should not be allowed to determine if you pass the classes! I KNOW my answers are correct. I've done this for years. It's so frustrating to not be able to pass because some students don't know what they're doing.
