Scenario 1: Each character typed causes an interrupt service routine to execute for 0.01 millisecond (to copy the character typed from the keyboard to memory). You can assume that a computer user is typing at an average rate of 200 characters per minute. Scenario 2: Every 50 milliseconds an interrupt service routine executes for 0.1 milliseconds and copies any buffered data from the keyboard to memory.

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.
