This assessment is being phased out, be sure to check the expiry date of the achievement standard.

For 2.44, students will need to do one project on data representation (each data representation guide contains two data types), three projects for encoding, and one project for human computer interaction. They must do one encoding project for each of the three encoding areas - compression, error control coding, and encryption.

The guides the student picks will depend on whether they are aiming for Merit/Excellence, or on just getting the credits. Note that Merit/Excellence for this standard requires time, commitment and a willingness to do additional reading.
