Lesson 3.3 Protocols and Standards

Description

In this lesson, students will learn about the many protocols and standards that are used to send and receive information across a network. Students will learn how networks use specific ports and protocols, each with a specific purpose, such as sending and receiving emails. Students will also learn about wireless networking standards and how frequency and channels relate to speed of data transmission.


Objective

Students will be able to:

  • Compare and contrast wireless networking protocols: 802.11.a 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax
  • Compare and contrast TCP and UDP protocols
  • Explain how networks use ports and protocols, each with a specific purpose. Ports reviewed include 21, 22, 23, 25, 53, 80, 110, 143, and 443
  • Explain how wireless standards use frequencies and channels to transmit data
