Short for host bus adapter. An HBA is an I/O adapter that sits between the host computer’s bus and the Fibre Channel loop and manages the transfer of information between the two channels. In order to minimize the impact on host processor performance, the host bus adapter performs many low-level interface functions automatically or with […]
- Human-Computer Interaction (HCI)
Short for human-computer Interaction, a discipline concerned with the study, design, construction and implementation of human-centric interactive computer systems. A user interface, such as a GUI, is how a human interacts with a computer, and HCI goes beyond designing screens and menus that are easier to use and studies the reasoning behind building specific functionality […]
Short for high-bandwidth digital-content protection, a specification developed by Intel for protecting digital entertainment content that uses the DVI interface. HDCP encrypts the transmission of digital content between the video source, or transmitter — such as a computer, DVD player or set-top box — and the digital display, or receiver — such as a monitor, […]
Short for High-level Data Link Control, a transmission protocol used at the data link layer (layer 2) of the OSI seven layer model for data communications. The HDLC protocol embeds information in a data frame that allows devices to control data flow and correct errors. HDLC is an ISO standard developed from the Synchronous Data […]
Handheld Device Markup Language is used to format content for Web-enabled mobile phones. HDML is Openwave’s (formerly known as phone.com) proprietary language, which can only be viewed on mobile phones that use Openwave browsers. HDML came before the WAP standard was created. It uses Openwave’s Handheld Device Transport Protocol (HDTP), instead of WAP. Phones access […]
