About this 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 w…

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.

Who is this class for: This class is designed for beginners in computing that want to understand the basics of how data is sent and received in a network and how small computer networks are created. People who may be in non-networking professions that would like to understand how their home or small business network works will enjoy this course. Previous networking knowledge is not required. This course is designed to provide an introduction to the basics of networking and will cover only a very small portion of the necessary knowledge and skills needed to achieve an entry-level Cisco networking certification. Access to a Windows 10 machine and a simulation tool called Cisco Packet Tracer is required to get the full benefit of the course.

Syllabus


WEEK 1


Principles of Communications



In this module, you will learn how protocols in computer networks are used to exchange data and information between hosts and devices. You will examine the standards and protocols used to send and receive data in a computer network. At the end of this module, you will examine a Windows computer to locate the physical or MAC address used send and receive data.
