Communication is successful when a message is sent, received and understood.
Communication means sharing information so someone understands it. A protocol is an agreed set of rules computers use to exchange information. A method is how a message is sent, such as email, video call or shared document.
Complete the four missions. You can use clues without losing your progress. Your first attempt at each task contributes to your accuracy score, but you can always correct a mistake and learn from it.
Reach 75% first-try accuracy across 12 core tasks to unlock the optional Expert Dispatch challenge. If you score below that, you can save your report and replay to improve.
Save any time: press the yellow button at the top. Your PDF is one record with your answers, corrections, personal reflection and an achievement panel. No separate certificates.
