detail.

Answer 1

Defenitions: To know the concept of the "How do peripheral devices interact with the operating system to provide input and output?" , we have to first know what is peripheral devices, how's it works and their protocols and what is Operating System.

Peripheral Devices:

• A peripheral device, also sometimes called an auxiliary device.
• Input output devices attached to the computer are called peripheral device.
• There are three types of peripheral devices"

1. input
2. output
3. input-output

• peripheral may be Anolog Or Digital and serial or parallel.
• A peripheral device is a device that is connected to a computer/ but is not part of the core computer architecture. The core elements of a computer are the central processing unit, power supply, motherboard and the computer case that contains those three components.
• A peripheral device is any connected device, internal or external, that provides a computer with additional.
• examples: monitor and printer.keyboard, magnetic tape etc.

Protocols:

• Each peripheral is programmed with its own machine code. Each has its own rules that dictate how it transmits data values between the computer and the device. These rules make up a protocol for controlling and communicating with the device.

The OS uses programs called device drivers to manage connections with peripherals.

A device driver:

• A device driver handles the translation of requests between a device and the computer
• A device driver defines where a process must put outgoing data before it can be sent, and where incoming messages will be stored when they are received
• A device driver wakes up the device when it is needed and put it back to sleep when it is not.

Operating system(OS):

An operating system is software that manages computer hardware and software. It supplies an interface for the user and important utilities for managing the computer.

How do peripheral devices interact with the operating system to provide input and output:

• An OS have generic device drivers to enable it to connect to most common peripherals. Some peripherals, however, will have their own drivers that need to be installed before use.
• Peripherals that use the same protocol may be controlled by the same driver. If a number of identical game controllers are plugged in, each device will store its data in a different place so they do not interfere with each other.

The input-output (I/O) organization of a computer is a function ,the size of computer and the devices connected to it.

Input-output interface:

• its provides the method for transferring the information between internal storage and external input-output devices.
• Peripherals connected to computer need special connection link for interfacing them with the CPU.
• Computer system include special H/W CPU and Peripherals to supervise and synchronize all I/O transfer ,these component called interface units.
