About the Course

Welcome to the second of five courses in the Cisco Networking Basics Specialization. Have ever wondered how devices on computer networks truly communicate? There are specific protocols or rules and standards that every device must follow to access the Internet and to communicate over a network. In this course, you will examine the principles of network communication, how networks are designed and what specifically is being sent and received by different devices when we send pictures, text messages, video or any other data across the network. What exactly is sent and how is it sent are the questions that will be answered in this course. At the end of this course, you will be able to: 1. Explain how protocols and standards benefit a global internetwork. 2. Describe how the Ethernet Protocol transmits data within a LAN. 3. Explain IPv4 addressing and the role subnet masks. 4. Use Cisco Packet Tracer to connect hosts to a wireless router in a LAN. 5. Use a protocol analyzer or "packet sniffer" to open and examine a data packet that has been transmitted across a network. 6. Examine a Windows computer to locate the physical or MAC address used send and receive data....

my only comment is that I felt the peer review assignment questions could have been clearer as really there are a number of possible answers to why did you pick a particular private ip range.

A really useful course for beginners. Great content and practice materials. This course would probably enable you to install or troubleshoot your own home network, either wired or wireless!!

Course material is interesting. It is taught at a very basic level. The course structure could use work. The order of lessons is odd (explaining subnets isn't done until the last unit) and some significant content areas are skipped (IP addressing of switches and other devices that don't normally get an IP address, command line configuration of networking equipment). The discussion forum doesn't seem to be moderated by an instructor, which would be useful when there are questions on course content.

The course is really explained in a good and simplified manner but there's a problem with the many readings because they're needed to be replaced by videos because I want someone with more experience to explain this as in old school

Really good course. Interesting, relevant topic, well thought out readings and videos. Wish there were some more resources going into the final exam, but otherwise I definitely learned a ton and don't regret the time spent.
