This is a full lesson on data transmission with all resources / activities. I use this for a double lesson of around 1 hour and 50 minutes and it provides a thorough understanding of simplex / duplex transmission and then goes on to look at serial / parallel transmission before finishing with odd and even parity bits and then parity blocks.
The Learning Objectives are:
- Understand what is meant by transmission of data
- Know the difference between serial and parallel data transmission
- understand of the reasons for choosing serial or parallel data transmission
- Know why it is necessary to check for errors
- Understand how parity works to identify if an error has occurred / locate errors
Resources included:
- Parallel Ports Handout
- Serial Port Handout
- Lesson Presentation
- Parity demonstration
- Parity Puzzle Plenary
The aim of all my resources is to provide lessons / activities of good quality that will add value to your lessons / schemes of work.
All activities and resources have been used in class and any errors will be fixed and resources updated as soon as I am aware of any errors. I have priced my resources at what I consider to be a reasonable cost based upon the amount of effort and work I have put into them but all comments and suggestions are very welcome and will be used to improve future resources.
If you have an idea for a topic / resource that you would like to see, feel free to leave a comment.
