KYK-13 on display at the National Cryptologic Museum.. The KYK-13 Electronic Transfer Device is a common fill device designed by the United States National Security Agency for the transfer and loading of cryptographic keys with their corresponding check word.
This gives the user the chance to prevent the keylogger from "phoning home" with his or her typed information. Automatic form-filling programs can prevent keylogging entirely by not using the keyboard at all. Most keyloggers can be fooled by alternating between typing the login credentials and typing characters somewhere else in the focus window.
Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with n-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed.
Typewriters are the definitive ancestor of all key-based text entry devices, but the computer keyboard as a device for electromechanical data entry and communication largely comes from the utility of two devices: teleprinters (or teletypes) and keypunches. It was through such devices that modern computer keyboards inherited their layouts.
Jef Raskin advocated designing devices in ways that prevent erroneous actions. [5] Don Norman suggests changing the common technical attitude towards user error: Don't think of the user as making errors; think of the actions as approximations of what is desired. [6]
An information appliance (IA) is an appliance that is designed to easily perform a specific electronic function such as playing music, photography, or editing text. [ 1 ] [ 2 ] Typical examples are smartphones and personal digital assistants (PDAs).
Each device is given its Device Keys and a 31-bit number d called the device number. For each Device Key, there is an associated number denoted the path number, the “u” bit mask, and the “v” bit mask. The path number denotes the position in the tree associated with the Device Key. This path number defines a path from the root to that ...
UDID is an acronym for Unique Device Identifier. The UDID is a feature of Apple's devices running iOS, tvOS, watchOS, and macOS. It is a unique identifier that is calculated from different hardware values, such as the ECID. It is sent to Apple servers when a user tries to activate the device during Setup.
