The first release in 1994 included original Centronics mode ("compatibility mode"), nibble and byte modes, as well as a change to the handshaking that was already widely used; the original Centronics implementation called for the BUSY lead to toggle with each change on any line of data (busy-by-line), whereas IEEE 1284 calls for BUSY to toggle ...
A compatibility mode in an operating system is a software mechanism in which a computer's operating system emulates an older processor, operating system, and/or hardware platform in order to allow older software to remain compatible with the computer's newer hardware or software. This differs from a full-fledged emulator in that an emulator ...
Nibble Mode is an interface that allows the device to transmit data four bits (a nibble) at a time, (re)using four of the status lines of Compatibility Mode for data. This is the Bi-tronics mode introduced by HP and is generally used for enhanced printer status. Although never officially supported with these, Nibble Mode works with most of the ...
The five-volume set of the x86-64 Architecture Programmer's Manual, as published and distributed by AMD in 2002. x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [note 1] is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new ...
I3C uses open-drain mode when necessary for compatibility, but switches to push-pull outputs whenever possible, and includes protocol changes to make it possible more often than in I²C. SCL is a conventional digital clock signal , driven with a push-pull output by the current bus controller during data transfers.
Interoperability. An example of software interoperability: a mobile device and a TV device both playing the same digital music file that is stored on a server off-screen in the home network. Interoperability is a characteristic of a product or system to work with other products or systems. [1] While the term was initially defined for ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Electromagnetic compatibility. Anechoic RF chamber used for EMC testing (radiated emissions and immunity). The furniture has to be made of wood or plastic, not metal. Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional ...
