Header files contains the signature of library functions.
Using these functions it reduces the time of the programmer .
List of some library Functions:(in C Language)
- printf()
- scanf()
- sqrt()
- strcpy()
- strcmp()
Answer:
2 x 10⁵ bytes per second
Explanation:
Given:
MIPS rate = maximum speed of CPU to execute instructions = 10 million instructions per seconds
number of instructions required to transfer 1 byte using interrupt driven I/O = 50
Maximum number of bytes that can be transferred in 1 second = MIPS rate / number of instructions for 1 byte
=> max number of bytes = 10 million / 50 = 10 x 10⁶ / 50 = 2 x 10⁵
which is less than the maximum transfer rate of memory = 100 million bytes per second
So, maximum data transfer rate during I/O operations by using interrupt-driven I/O is 2 x 10⁵ bytes per second
