Answer the following Question :
The read access delay for an I/O system is defined as the time required for the device to acquire the requested data and prepare to start transmitting the data.
The data transfer rate for an I/O device is defined as the number of bytes per second that it can transmit. Suppose that there are two different I/O systems A and B. After an access delay of 5 seconds, system
A transfers data at the rate of 5120 bytes per second. After an access delay of 4 seconds, system B transfers data at the rate of 3072 bytes per second.
a) How long will each system require to complete a 3145728-byte I/O request?
b) How long will each system require to complete a 3072-byte I/O request?
c) For what value of N would an I/O request of size N bytes, require the same amount of time to complete on each of the two systems?
