What are input peripherals and what are they for?

The input peripherals they are the devices that allow information or data to be entered into a computer, so that they can be processed or sorted. It is important to highlight that when denominated as peripherals it seeks to highlight that they are often additional but not essential, although in certain cases it is clear that peripherals are fundamental to the computer system.

The input peripherals serve then as a component class that is responsible for providing data to the computer, taking into account that without this kind of instructions it will be impossible to attempt any kind of operation. It is only necessary to think of examples such as keyboard or mouse, which are the components that are most played and used in a computer system to give instructions.

Types of input peripherals

Pointing device They are the input peripherals that act as signaling devices or pointers, which are used for the specification of a position in space.

  • Direct If the input space matches the exhibition space, for example, if that space has a visual feedback with the cursor that is seen or appears. The touch screens They are an example.
  • Hint If participation is indirect to be guided in space like the ratn or trackball.

Keyboards It is a device with a distribution of buttons and keys, where each key or button is used to enter data into the computer. In that sense any language character is processed when pressed and when calling a particular function of the computer.

Composite devices They have buttons, push buttons and joysticks, which are combined in a unique device and that is physical. Almost all video game devices feature this kind of controller. In a technical sense a mouse is a composite device.

High degree of freedom The truth is that due to their characteristics, the input devices can be very diverse and difficult to simplify in a grouping. For that reason we have to think about developments such as peripheral devices, 3D camera applications, virtual reality, etc.

Sound input devices They are also known as recorders and are designed to capture sounds. In certain cases an audio output can be used as an input device for capturing produced sound.

Image and video input peripherals In short, they are the camcorders, VCRs, the photo cameras, etc. They are used to capture videos or images from the outside world to be sent to the computer.

Examples of input peripherals

  • The mouse or mouse.
  • Trackball or the tracking ball that is part of the mouse layout.
  • The keyboard in its different versions: QWERTY, AZERTY, Braille, Colemak, Dvorak, HCESAR, etc.
  • The optical pencil.
  • The touchpad
  • The joystick
  • A joystick
  • Virtual reality equipment
  • Video game controllers
  • A gamepad
  • A paddle for video games.
  • Wii Remote
  • A flyer for video games.
  • A microphone
  • MIDI or Musical Instrument Digital Interface.
  • Digital cameras.
  • Scan 3D
  • Bar code reader (You can see how generate an online barcode here)
  • Fingerprint sensor.
  • Telmeter or telmeter laser.
  • A webcam.
  • For medical images: ultrasound, mammogram, magnetic resonator or tomograph.

Characteristics of the input peripherals

  • Connectivity The input peripherals are designed with the express objective of enabling the connection to the central computer system to always be the most efficient and to provide a good experience when sending the information or being processed.
  • Comfort Being input equipment, it is the user who interacts with them constantly. That is why the mouse, keyboard and the like have been adapted and improved to make it more and more comfortable for people to use.
  • In touch with the senses In one way or another, the input peripherals are devices that are used for the translation of instructions from the person to the equipment, either for a pointer to go where it is wanted or to process certain information such as a keyboard.
  • Registered historically Although the peripherals that are seen as most necessary are really old (keyboard, mouse), it does not seem that to date they will cease to exist or that there is already a patent in the market to replace them.
  • Adaptation The input devices have been maintained over time and according to the trend of the time they have been modified. An example of this are on-screen or digital keyboards.
