Which of the following is a principle that can improve the efficiency of i/o?
a) increase the number of context switches.
b) use small data transfers.
c) move processing primitives into hardware.
d) decrease concurrency using dma controllers

C)

Explanation:

One principle that can improve the efficiency of I/O would be to move processing primitives into hardware. Primitives are a semantic value representing something else such as words or numbers within the programming language. By moving them into hardware they system is able to read them at a much faster speed making the I/O more efficient.
