1)      Whenever you enter data into your computer, it is referred to as input.This can be text typed in a word processing document, keywords entered in a search engine's search box, or data entered into a spreadsheet.

2)      Input can be something as simple as moving the mouse or clicking the mouse button or it can be as complex as scanning a document or downloading photos from a digital camera.

3)      Devices such as the keyboard, mouse, scanner, and even a digital camera are considered input devices. This is because they allow the user to input data into the computer (yes, the word "input" can also be used as a verb).

4)      While input generally comes from humans, computers can also receive input from other sources. These include audio and video devices that record movies and sound, media discs that install software, and even the Internet, which is used to download files and receive data such as e-mail or instant messages.

An input device is any tool that feeds data into a computer. For example, a keyboard is an input device, whereas a display monitor is an output device. Mice, trackballs, and light pens are all input devices. Isn’t it amusing that under the dry title of “input devices,” we get such fun words as mice, joystick, trackball, touch pad, light pen, and puck?
1)      Keyboards
The keyboard is a way to input letters or numbers into different applications of programs. A keyboard also has special keys that help operate the computer. The most popular keyboard used today is the 101-keys QWERTY keyboard.
2)      Mouse
mouse function as a point-and-draw device by detecting two-dimensional motion relative to its supporting surface. We can use it only with GUI (Graphical user interface) based on operating system. E.g. Windows.
The main goal of any mouse is to translate the motion of your hand into signals that the computer can use.
3)      Trackballs
            A mouse variation, essentially a mouse lying on its back. Because the device is stationary, it does not require as much space on your desktop. The ball moves as you rotate it with your thumb, your fingers, or the palm of your hand; this saves wrist fatigue and reduces hand and arm movement. Trackballs are especially popular with those experiencing problems with arthritic hands. Trackballs come in various sizes and shapes.

4)      Light Pens
A light pen is fairly simple to implement. Just like a light gun, a light pen works by sensing the sudden small change in brightness of a point on the screen when the electron gun refreshes that spot. By noting exactly where the scanning has reached at that moment, the X,Y position of the pen can be resolved. This is usually achieved by the light pen causing an interrupt, at which point the scan position can be read from a special register, or computed from a counter or timer. The pen position is updated on every refresh of the screen. Let you move the pointer and select items on the display screen by directly pointing to the objects on the screen with the light pen.
5)      Touch Screens
A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. However, if the object sensed is active, as with a light pen, the term touchscreen is generally not applicable.
The touchscreen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a cursor controlled by a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand. Such displays can be attached to computers, or to networks as terminals. They also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games.
 Allow you to use your finger to touch the screen and choose objects. A special computer monitor or a monitor fitted with special hardware is necessary to provide touch screen capabilities.

6)      Graphic Tablet or Drawing Tablet.
These digitizers or graphic tablets are pressure-sensitive data input devices that respond to a user’s movement of a pen, mouse, or other device to select a graphic image. These are most often used for complex drawing and computer-aided design programs.
7)      Microphone
Using the microphone along with speech recognition software can offer a completely new approach to inputting information into your computer. Speech recognition programs, although not yet completely exact, have made great strides in accuracy as well as ease of use. The voice-in or speech recognition approach can almost fully replace the keyboard and mouse. Speech recognition can now open the computer world to those who may have been restricted due to a physical handicap. It can also be a boon for those who have never learned to type.

8)      Joystick
A joystick is used to move the cursor from place to place, and allow moves in all directions and controls the movement of cursor. If offers three types of control such as digital, glide, direct. They input directional data like a mouse but work by switches as the joystick is moved. It consist of a stick that rotate on axis and reports it angle or direction to the device it is controlling. A joystick is used mostly for computer games.
9)      Scanners
Peripheral products that input information in your computer. When you think of it, even the grocery store bar code scanners read imprinted code and transfer it to the store’s computerized cash registers.

10)  Digital Camera
A digital camera stores images digitally rather than recording them on film. Once a picture has been taken, it can be input or downloaded to your computer where it is stored for later use. The concept is the same whether you take a film photo and then use your scanner as an input device or take a photo with your digital camera and use the camera itself as an input device. In both cases, the image is input into the computer.
11)  Camera
Camera - most cameras like this are used during live conversations.  The camera transmits a picture from one computer to another, or can be used to record a short video. A webcam is a video capture device connected to a computer or computer network, often using a USB port or, if connected to a network, ethernet or Wi-Fi.
12)  CD
Compact Disc (CD) - CDs store information.  The CD can then be put into another computer, and the information can be opened and added or used on the second computer. Note:  A CD-R or CD-RW can also be used as an OUTPUT device.
13)  Disk Drive
Disk Drive - A disk drive can hold a CD or a floppy disk.  It reads the information on the disk so that the computer can use it.

14)  Bar Code Scanner
Bar Code Scanner - A bar code scanner scans a little label that has a bar code on it.  The information is then saved on the computer.  Bar code scanners are used in libraries a lot. A Bar Code is just a different way of encoding numbers and letters by using a combination of bars and spaces of varying widths. This is just another way of entering data into a computer. A bar code does not contain descriptive data. It is a reference number that a computer uses to look up an associated record that contains descriptive data and other important information. For example, a barcode found on a soda can does not contain the product name, type of soda, or price, instead, it contains a 12-digit product number. When this number is scanned by the cashier at the check-out, it is transmitted to the computer which finds the record associated with that item number in the data base. The matching item record contains a description of the product, vendor name, price, quantity-on-hand, etc. The computer instantly does a "price lookup" and displays the price on the cash register. It also subtracts the quantity purchased from the quantity-on-hand. This entire transaction is done instantly. In a nutshell, a bar code typically has ID data encoded in it, and that data is used by computer to look up all specific information associated with the data.

1)      A computer terminal is an electronic or electromechanical hardware device that is used for entering data into, and displaying data from, a computer or a computing system. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, but as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was timesharing systems, which evolved in parallel and made up for any inefficiencies of the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal.

2)      The function of a terminal is confined to display and input of data; a device with significant local programmable data processing capability may be called a "smart terminal" or fat client. A terminal that depends on the host computer for its processing power is called a thin client. A personal computer can run software that emulates the function of a terminal, sometimes allowing concurrent use of local programs and access to a distant terminal host system.

3)      Example of terminals are Point-of-Sale Terminals, Automated Teller Machines (ATM), and DVD Kiosks.


1)      This report is telling about the meaning of input devices. Devices such as the keyboard, mouse, scanner, and even a digital camera are considered input devices. This is because they allow the user to input data into the computer (yes, the word "input" can also be used as a verb).

2)      It’s defined  fourteen devices of input. There are keyboard, mouse, trackball, light pen, touch screen, drawing tablet, microphone, joystick, scanner, digital camera, camera, CD, Disk Drive and Bar Code Scanner.

3)      This report also explain about the function of the input devices and how to use it. It’s also tells about the uses of input devices in our daily life.

4)      It’s explain about the meaning of terminal too. We have always update about the latest input devices to make our work more easier. We also must be open-minded about the fast improvement of IT.

5)      There are much more example of input such as:
·         Apple software
·         Power glove
·         Digitisers
·         Head mounted virtual reality
·         Haptic
