KEYBOARD

A keyboard is an input device, partially modeled after the typewriter keyboard.

TYPES OF KEYBOARD

KEYBOARD

STANDARD(QWERTY) NON-STANDARD

STANDARD KEYBOARD

•A basic computer keyboard that does not have any advanced features has 84 keys.• The multimedia computer keyboard has 101 keys and these keys are often referred to as shortcuts or hot keys. • Some multimedia keyboards have 104 keys and such devices provide more features as compared to a keyboard with 101 keys.

NON-STANDARD

KEYBOARD•Non-Standard Keyboard let the user type in characters or commands by pressing a combination of keys.

• The chorded keyboard design is typically used for hand-held computers that cannot accommodate standard-sized keyboards.

MOUSE

SCANNER

•A scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. • Scanners typically read red- green-blue color (RGB) data from the array. This data is then processed with some proprietary algorithm to correct for different exposure conditions, and sent to the computer via the device's input/output interface

BIOMETRICS

• When referring to computers and security, biometrics is the identification of a person by the measurement of their biological features. For example, a user identifying themselves to a computer or building by their finger print or voice is considered biometrics identification.

• When compared to a password, this type of system is much more difficult to fake since it is unique to the person. Below is a listing of some known biometric devices.
