3 (a) (b) Explain the procedure how processor execute an instruction written in machine language with diagram. CPU of the computer system communicates with the memory and I/O devices in order to transfer data between them. Now describe the method of communication between CPU and memory with proper diagram. A 32-bit computer has three selector channels and two multiplexor channels. Each selector channel supports three magnetic disk and three magnetic tape units. Each multiplexor channel has three line printers, three card readers, and 20 VDT terminals connected to it. Assume the following transfer rates: Disk drive Magnetic tape drive Line printer Card reader VDT 800 Kbytes/s 200 Kbytes/s 6.6 Kbytes/s 1.2 Kbytes/s 1 Kbyte/s Estimate the maximum aggregate I/O transfer rate in this system in case that all the five channels transfer data simultaneously.
