Course Learning Goals
Students will:
- explain the OSI (Open Standards Interface) and TCP/IP (Transmission Control Protocol/Internet Protocol) models and how they define data transmission;
- describe and configure important network protocols and implement logical addressing schemes;
- configure, maintain, and troubleshoot network connectivity devices and transmission media;
- implement network architecture with basic network security, including encryption;
- explain the scientific method of analysis and apply it in a variety of situations to solve networking problems, including data transmissions errors, hardware faults, malware, and configuration errors [Scientific Literacy]; and
- given a scenario, plan and implement a basic SOHO (small office/home office).
