• Online, Self-Paced

This course covers the OSI layers, and you will discover where devices, services, and protocols reside. You'll also explore well-known protocols and their associated port numbers.

Learning Objectives

Ports and Protocols

  • start the course
  • describe the TCP protocol
  • describe the IP protocol
  • describe the UDP Protocol
  • describe the ICMP Protocol
  • recognize when to use connection-oriented protocols
  • recognize when to use connectionless protocols
  • list the well-known UDP and TCP ports

Practice: Port Assignments

  • describe which protocols and ports are in use by certain services

OSI Layers

  • describe the purpose of the OSI model
  • list the devices, applications, protocols, and services that function at the physical layer
  • list the devices, applications, protocols, and services that function at the data link layer
  • list the devices, applications, protocols, and services that function at the network layer
  • list the devices, applications, protocols, and services that function at the transport layer
  • list the devices, applications, protocols, and services that function at the session layer
  • list the devices, applications, protocols, and services that function at the presentation layer
  • list the devices, applications, protocols, and services that function at the application layer

Practice: OSI Characteristics

  • list characteristics of each OSI layer
