Question

Define input output and storage device explain briefly with example

Answer 1

Answer:

Input devices:

An input device can send data to another device, but it cannot receive data from another device. Examples of input devices include the following.

Keyboard and Mouse - Accepts input from a user and sends that data (input) to the computer. They cannot accept or reproduce information (output) from the computer.

Microphone - Receives sound generated by an input source, and sends that sound to a computer.

Webcam - Receives images generated by whatever it is pointed at (input) and sends those images to a computer.

Output devices:

An output device can receive data from another device and generate output with that data, but it cannot send data to another device. Examples of output devices include the following.

Monitor - Receives data from a computer (output) and displays that information as text and images for users to view. It cannot accept data from a user and send that data to another device.

Projector - Receives data from a computer (output) and displays, or projects, that information as text and images onto a surface, like a wall or a screen. It cannot accept data from a user and send that data to another device.

Speakers - Receives sound data from a computer and plays the sounds for users to hear. It cannot accept sound generated by users and send that sound to another device.

Storage device:

Storage devices are one of the core components of any computing device. They store virtually all the data and applications on a computer, except hardware firmware. They are available in different form factors depending on the type of underlying device. For example, a standard computer has multiple storage devices including RAM, cache, and hard disk, as well as possibly having optical disk drives and externally connected USB drives.

There are two different types of storage devices:

Primary storage devices: Generally smaller in size, these are designed to hold data temporarily and are internal to the computer. They have the fastest data access speed, and include RAM and cache memory.

Secondary storage devices: These usually have large storage capacity, and they store data permanently. They can be either internal or external to the computer, and they include the hard disk, optical disk drive and USB storage device.
