Answer:
b. the interface between the hard disk and the system bus
Explanation:
A controller, in the most basic computing terms, is a hardware chip or card that falls between two hardware components. Thus, a computer’s motherboard will always have a controller that interfaces with RAM, hard disk, DVD drives or other hardware components. Being an interface between two hardware devices facilitate incoming and outgoing commutations. Option B therefore, is the correct answer because it interfaces between the hard disk and sytem bus, which are both hardware components.
Answer:
A storage device is a device used to keep softcopy for future reference
Answer:
n2.
Explanation:
The function with the time complexity of n2 is the fastest growing function is in terms of square.As n increases the time complexity will grow very rapidly.
n=1 n2=1
n=2 n2=4
n=3 n2=9
n=4 n2=16
n=5 n2=25.
The slowest growing function among them is log n then n and then n log n.
n log n is better than n2.
