Input from the user to the computer can come through many peripheral devices such as the keyboard, mouse, touch-screen, a modem or a web camera.
By knowing that they want to do. What you need the computer for will determine what input devices you require.
A keyboard.
An input mask refers to controlling the input that a user is going to provide.For example, if you were going to ask for a person's phone number, and you know the format of the phone number is going to be (xxx) xxx-xxxx, then you would set an input mask forcing the input to be in that format.A zip code, for example, is 5 or 9 characters in the U.S..... either 12345 or 12345-6789.Therefore, you would use an input mask that looked like xxxxx | xxxxx-xxxxThis controls the user's input so that less validation is required later.Input masks are mostly used to validate input that has a strict pattern that never changes. With Access validation rules you can validate more complex patterns.
An input method is an operating system component or program that allows users to enter characters and symbols not found on their input device. For instance, on the computer, this allows the user of 'Western' keyboards to input Chinese, Japanese, Korean and Indic characters. Most operating systems use the term input method. It is commonly called input method editor(IME) in the Microsoft Windows operating systems.
A bar code scanner is an input device. While it does contain a laser, the laser is used to read the data, not to communicate anything to the user. The bar code scanner reads the UPC codes into the cash register or point of sale system.
"print" will output a value onto the screen for a user to see. "input" or "raw_input" gets a user's input.
To insure that the users input is valid.
it is an input from a user from the real world(a real world input) that is input from either sensors or user input data to a real time application or any other type of applications.
yes it does.
the input device get input from user.. output device display the result....
An input device is a device which is used by the user to enter data into the computer system. An output device is a device which is used by the computer to send data back to the user in a way that the user can understand. It is possible for a device to be both an input and output device simultaneously. For example a force-feedback joystick takes input from the user, but also communicates to the user with a series of vibrations or force-actions.
A graphics tablet is used to to accept user input to the computer so is classed as input device ...
Its an output device. By visual display unit I assume you're referring to one of the following: a tv, a computer monitor or a laptop screen. All 3 are output devices. The difference b/w an input and an output device is simply user input. An input device receives input from a user, an output device does not. A mouse (receives user clicks), A microphone (receives user audio), a keyboard are input devices.
1)Use fingers to move things 2)Use mouse
why different user interfaces require the use of different types of input device
most/all input devices are with a software called glovepie.
respond to user input.
