Peripheral devices expand the functionality of computers and include input and output devices. Some examples are: - A light pen allows a user to point at and draw on a display screen like a touchscreen but with greater accuracy. - A cooling pad helps reduce the operating temperature of laptops to protect them from overheating. - An image scanner optically scans images, text, and objects and converts them to digital files. - Memory cards store digital data and are commonly used in portable electronic devices like cameras, phones, and laptops.

1. Advance Peripheral Devices
What They Are And Why They Used

2. WHAT IS PERIPHERAL DEVICES ?

3. LIGHT PEN
 A Light Pen is a computer input device in the form of a light sensitive wand used in
conjunction with a computer’s display.
 It allows the user to point to displayed objects or draw on the screen way to a
touchscreen in a similar way to a touchscreen but with greater positional accuracy

4. COOLING PAD
• A laptop/notebook cooler, cooler pad or chill mat is an accessory for laptop computers
that helps reduce their operating temperature, which is normally used when the
laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both
the laptop from overheating and the user from suffering heat related discomfort.

5. OTG
On-The-Go, that allows USB Devices, such as digital audio player or mobile phone to act as a
host, allowing other USB devices, such as USB Flash Drives, Digital Cameras, Mouse or
keyboards , to be attached to them. Use of USB OTG allows those devices to switch back and
forth between the roles of host and device. For instance, a mobile phone may read from
removable media as the host device, but present itself as a USB Mass Storage Device when
connected to a host computer.

6. Image Scanner
• In computing, an image scanner often abbreviated to just scanner, although the
term is ambiguous out of context (barcode scanner, CAT scanner etc.) is a device
that optically scans images, printed text, handwriting or an object and converts it
to a digital image.

7. MICROPHONE
 A microphone, is a transducer that converts sound into an electrical signal.
 Microphones are used in many applications such as telephones, hearing aids, public address systems for
concert halls and public events, motion picture production, live and recorded audio engineering, two-
way radios, megaphones, radio and television broadcasting, and in computers for recording
voice, speech recognition and for non-acoustic purposes such as ultrasonic checking or knock sensors.

8. MEMORY CARD
• A memory card or flash card is an electronic flash memory data
storage device used for storing digital information. These are
commonly used in portable electronic devices, such as digital
cameras, mobile phones, laptop computers, tablets, MP3
players and video game consoles.

9. Router
A router[a] is a networking device that forwards data packets between computer networks.
Routers perform the traffic directing functions on the Internet. A data packet is typically
forwarded from one router to another through the networks that constitute
the internetwork until it reaches its destination node.[2]

10. EXTERNAL HARD DISK
SSD :- Solid State Drive is storage device that uses “IC” assembles as
memory to store data persistently. SSD Technology have write speed
is 654 mbps and read speed is 712 mbps.
HDD :- A hard disk drive is storage device used for storing and
retrieving digital information using one or more rigid rapidly rotating
disks (Platers) coated with magnetic material. HDD Technology have
write speed is

11. MICRSOFT HoloLens
– Microsoft HoloLens, known under development as Project Baraboo, is a pair of mixed
reality head-mounted smartglasses developed and manufactured by Microsoft. HoloLens gained
popularity for being one of the first computers running the Windows Holographic platform
under the Windows 10 operating system.

12. WEBCAM
• A webcam is a video camera that feeds or streams its image in real time to or
through a computer to computer network. When "captured" by the computer, the
video stream may be saved, viewed or sent on to other networks via systems such as
the internet, and email as an attachment. When sent to a remote location, the video
stream may be saved, viewed or on sent there. Unlike an IP camera (which connects
using Ethernet or Wi-Fi), a webcam is generally connected by a USB cable, or similar
cable, or built into computer hardware, such as laptops.

13. Joy stick
• A joystick is an input device consisting of a stick that pivots on a base and
reports its angle or direction to the device it is controlling. A joystick, also
known as the control column, is the principal control device in
the cockpit of many civilian and military aircraft, either as acenter
stick or side-stick. It often has supplementary switches to control various
aspects of the aircraft's flight.

14. TV TUNER BOX
• A TV TUNER CARD IS A KIND OF TELEVISION TUNER THAT ALLOWS TELEVISION SIGNALS TO BE RECEIVED
BY A COMPUTER. MOST TV TUNERS ALSO FUNCTION ASVIDEO CAPTURE CARDS, ALLOWING THEM TO
RECORD TELEVISION PROGRAMS ONTO A HARD DISK MUCH LIKE THE DIGITAL VIDEO RECORDER

15. Hub
 A USB hub is a device that expands a single Universal Serial Bus (USB) port into
several so that there are more ports available to connect devices to a host system,
similar to a power strip.
 USB hubs are often built into equipment such as computers, keyboards, monitors,
or printers. When such a device has many USB ports, they all usually stem from
one or two internal USB hubs rather than each port having independent USB
circuitry.

16. Game Pad
 A gamepad (also called joypad), is a type of game controller held in two hands,
where the fingers (especially thumbs) are used to provide input. They are typically
the main method of input for video game consoles.

17. GRAPHIC TABLET
• A graphics tablet (also known as a digitizer, drawing tablet, digital drawing
tablet, pen tablet, or digital art board) is a computer input device that enables a user
to hand-draw images, animations and graphics, with a special pen-like stylus, similar to
the way a person draws images with a pencil and paper. These tablets may also be
used to capture data or handwritten signatures. It can also be used to trace an image
from a piece of paper which is taped or otherwise secured to the tablet surface.
Capturing data in this way, by tracing or entering the corners of linear poly-lines or
shapes, is called digitizing.
