Similarly, typewriter repair people used to refer to "a loose nut behind the keyboard" or a "defective keyboard controller." The broadcast engineering or amateur radio version is referred to as a "short between the headphones". Another term used in public safety two-way radio (i.e. police, fire, ambulance, etc.) is a "defective PTT button ...
With the release of the iMac in 1998 the traditional Mac serial port—and thus, the ability to use both LocalTalk and PhoneNET—disappeared from new models of Macintosh. LocalTalk-to-Ethernet bridges were introduced to allow legacy devices (especially printers) to function on newer networks. For very old Macintosh computers, LocalTalk remains ...
A Hardware keylogger for USB-Keyboards. Hardware keyloggers are used for keystroke logging, a method of capturing and recording computer users' keystrokes, including sensitive passwords. [1] They can be implemented via BIOS-level firmware, or alternatively, via a device plugged inline between a computer keyboard and a computer. They log all ...
USB keyboards, mice, and I/O devices are the most common devices connected to a KVM switch. The classes of KVM switches discussed below are based on different types of core technologies, which vary in how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. (USB-HID = USB Human Interface Device)
It integrates a webcam, speakers and microphone, as well as several ports (ethernet, FireWire 800, USB 2.0, and a downstream Thunderbolt port). [ 2 ] The Thunderbolt Display was discontinued in June 2016, and replaced by LG UltraFine displays Apple developed with LG on the consumer end, while the Pro Display XDR succeeded it in 2019 as Apple's ...
The USB HID keyboard interface requires that it explicitly handle key rollover, with the full HID keyboard class supporting n-key rollover. However, the USB boot keyboard class (designed to allow the BIOS to easily provide a keyboard in the absence of OS USB HID support) only allows 6-key rollover.
Although both FireWire and USB have bandwidth that must be shared by all devices, most modern operating systems are unable to monitor and report the amount of bandwidth being used or available, or to identify which devices are currently using the interface. [citation needed]
The Apple Display Connector is physically incompatible with a standard DVI connector. The Apple DVI to ADC Adapter, [1] which cost $149US at launch but was in 2002 available for $99US, [2] takes USB and DVI connections from the computer, adds power from its own integrated power supply, and combines them into an ADC output, allowing ADC monitors to be used with DVI-based machines.
