Write a half page description of the difference between CSMA/CD and CSMA/CA. We covered CSMA/CD in class on Monday, February 26th. CSMA/CD is more common than CSMA/CA and ethernet uses the CSMA/CD approach. You might want to include a diagram or two to demonstrate and to develop your understanding of the difference between CD and CA methods. www.google.com will give you lots of links to information about these two protocols. All of your description has to be in your own words. You may quote sources if you want to quote something, but the bulk of the description should be your own attempt to describe the difference. Due: Monday, March 31st.
