1. Input, Output, Storage Devices

2. Input Devices
In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mice, scanners, digital cameras and joysticks. Input devices allow us to enter new data into a computer. The computer processes the data and then produces outputs that we can understand using an output device. Input devices can be manual or automatic.

4. Output Devices
An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form. An example of this speakers, headphones and a monitor.

6. Storage devices
alternatively referred to as digital storage, storage, storage media, or storage medium, a storage device is any hardware capable of holding information either temporarily or permanently.
There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, like a hard drive. Secondary storage can be removable, internal, or external storage. The picture shows an example of aDrobo, an external secondary storage device.
Without a storage device, your computer would not be able to save any settings or information and would be considered a dumb terminal.
