What types of accounts are available in ArcGIS Online? Compare their capabilities

Organizational account - used to fully access the functionality and data sets available. Can also use premium content if the organization has credits. Is not free to use Public account - free but very limited do not have the same access and services that you would get with an organizational account

Why are domains especially useful when preparing for data collection using mobile devices?

Save time by not entering data, avoid typos, and use the same terminology

Describe the similarities and differences between tasks and models

Tasks and models both guide how a sequence of steps should be executed to convert data into a final result. Models are used to tell ArcGIS Pro how to automatically how to follow a sequence of steps and is good for automatic calculations that would be tedious to repeat. Tasks tell another user how to follow a sequence of steps and are good for guiding users on how to use specific data to get desired results
