The Bits and Bytes of Computer Networking

Google develops networking from an introduction through network, transport and application layers. Services and internet connections lead into troubleshooting and future developments. The layered progression helps learners connect a visible application problem with the different parts of a network, rather than assuming every connection failure has the same cause.

What you will learn

• Explain the roles of network layers.
• Relate networking services to internet connectivity.
• Use a layered approach to describe troubleshooting.

Who this suits

Beginner-level learners; detailed prerequisites are not specified in the published course facts.

Before you enroll

Use an isolated lab or a network you are permitted to administer. Check the required software, cloud resources and exercise access before enrolling, and document changes so the practice environment can be restored.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Describe a fictional failed web request at several network layers. Identify an observation that would help distinguish a name-resolution problem from a connection problem.
