1.A 32-bit computer has two selector channels and one multiplexor channel. Each selector channel supports two magnetic disk and two magnetic tape units. The multiplexor channel has two line printers, two card readers, and five VDT terminals connected to it. Assume the following transfer rates.

Disk drive                               700 Kbytes/s

Magnetic tape drive                200 Kbytes

Line printer                             6.6 Kbytes/s

Card Reader                            1.2 Kbytes/s

VDT                                        1 Kbytes/s
