I have learned about the three disabiities in general: Impairment; accommodation and acessibility.
Impairment is a medical and physical term limitinf one's ability to perform activities a normal person can do; accommodation is for the instructor to be able to provide extra time, materials and strategy for the impaired student to catch up and perform such skills; accessibility is making a lesson or skill accessible to the student.
By making instructor aware of these disabilities, instructions in online may be enhanced and more effective
