A 32-bit computer has two selector channels and one multiplexor channel. Each selector channel supports two magnetic disks 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             The magnetic tape drive                200 Kbytes             Line printer                             6.6 Kbytes/s             Card Reader                            1.2 Kbytes/s             VDT                                        1 Kbytes/s Estimate the maximum aggregate I/O transfer rate in this system.

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.
