Explanation:

1. Computer memory is mainly divided into primary storage (which includes RAM for temporary data access and ROM for permanent - like firmware storage) and secondary storage (such as HDDs and SSDs for long - term data storage). So the two main types are primary storage and secondary storage.
2. Input devices take human - generated input such as keystrokes, mouse movements, audio, etc., and convert it into machine - understandable language (binary code).
3. Output devices are responsible for presenting the results of computer processing to the user, such as monitors showing visual output, speakers playing audio output.

Answer:

1. Primary storage and secondary storage
2. Convert human input into machine language
3. Devices that provide output from the computer to the user
