I-TERMS


Trackback: A type of peer-to-peer communication system that was designed to send notification of updates between two websites via a Trackback Ping. Pings are small messages sent from one web server to another. TrackBacks are useful for informing a website that you have referenced its website within your own and is popular with bloggers.

SLI: “Scalable Link Interface” links two graphics cards together to provide scalability and increased performance. It takes advantage of the increased bandwidth of PCI Express bus architecture, and features hardware and software innovations. Depending on the application, SLI can deliver as much as two times the performance of a single GPU configuration.

BitTorrent: A file distribution system used for transferring files across a network of people. As you download a file, BitTorrent places what you download on upload for other users; when multiple people are downloading the same file at the same time they upload pieces of the file to each other. BitTorrent pieces together the file you are downloading, to where the first part of a file you get may be the last part someone else gets. As you continue to retrieve the file, BitTorrent also uploads data to other users.

Microarchitecture: The resources and methods used to achieve architecture specification. The term typically includes the way in which these resources are organized as well as the design techniques used in the processor to reach the target cost and performance goals. The microarchitecture essentially forms a specification for the logical implementation.

RDI: “Remote Debug Interface” is an Application Programming Interface (API) that defines a standard set of data structures and functions that abstract hardware for debugging purposes. It serves as a useful and widely adopted interface between debuggers and debug target (simulators, emulators and monitors) for ARM architecture.

EFI: “Extensible Firmware Interface” is primarily intended for IA-32 and Itanium architecture-based computers. EFI specification defines a model for the interface between operating systems and platform firmware. The interface consists of data tables that contain platform-related information, plus boot and runtime service calls that are available to the operating system and its loader. Together, these provide a standard environment for booting an operating system and running pre-boot applications.

GPT: “Globally Unique Identifier (GUID) Partition Table” is a new type of disk partitioning system. Unlike Master Boot Record (MBR) partitioned disks, data critical to platform operation is located in partitions instead of unpartitioned or hidden sectors. GPT partitioned disks have redundant primary and backup partition tables for improved partition data structure integrity.

ESRB: “Entertainment Software Rating Board” is a self-regulatory body for the interactive entertainment software industry established in 1994 by the Entertainment Software Association (ESA). ESRB independently applies and enforces ratings, advertising guidelines, and online privacy principles adopted by the computer and video game industry.

Cuckoo Egg: An edited MP3 file that appears to be a copyright protected song being distributed via the internet without the permission of the copyright owner. The initial portion (first 30 seconds or so) is the real song. The remainder of the song, however, is overwritten by something other than the initial song; usually cuckoo clock sound effects or or a series of random sounds and noises which are free of any copyright ownerships. Cuckoo Eggs have the correct file size and playing time as the original copyrighted MP3 file will have.

Watchdog: A device used to protect a system from specific software or hardware failures that may cause the system to stop responding. The application is first registered with the watchdog device. Once the watchdog is running on your system, the application must periodically send information to the device. If it doesn’t receive this signal within the set period of time it would execute the proper keystrokes to reboot the machine or restart the application.
