Answer:The impressive functions performed by computers involve only the simplest manipulations of 1s and 2s.
Explanation: The function performed by the computer system for the evaluation and manipulation involve the inclusion of 0s and 1s. 1s and 0s are used for the storage of data/information, on off state of the function or device etc.
So, the special functioning of the computer is not done by 1s and 2s rather than accomplished by 1s and 0s. Other options that are mentioned in the question are correct except the manipulation of the function by the involvement of 1s and 2s.
