A certain computer has a memory of 1M words, and each word is 32 bits long. Each instruction is 32 bits long and is consisted of an opcode field, a register address field to specify one of 32 registers, and a memory address field. How large must the register field be? How large must the address field be? How many different opcodes can be supported by this format? Show your reasoning

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.
