Communication is a key function of computer networks, and there are various messaging, voice, and video services available to facilitate it. Voice and video protocols that transfer real-time data bring their own challenges for network architecture, and you need to understand these performance demands to build networks that can support them.

As you study this lesson, answer the following questions: 

  • What is the difference between mail transfer and mailbox access protocols?
  • How does VoIP differ from traditional phone service? 
  • What is the difference between a hard VoIP phone and a soft VoIP phone?
