Course Description
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
