Unit 9: Networking
Computer networking has become an increasingly important field. When we discuss networking, we are not just referring to connecting computers together in one location but also about broader connections through the Internet.

Completing this unit should take you approximately 11 hours.

  explain basic networking principles;
  discuss protocols and how they are used; and
  explain reference models, particularly TCP/IP and OSI.
