KembaraXtra-Computer Terms – .avi:
.avi is a file extension used to identify audiovisual files stored in the Microsoft RIFF format. Files with this extension contain both audio and video data combined into a single file structure. The extension indicates that the file follows the Audio Video Interleaved format used primarily in Microsoft Windows multimedia systems. These files are commonly used for storing digital video content along with synchronized sound.

KembaraXtra-Computer Terms – auxiliary storage:
Auxiliary storage refers to any storage medium used to store data that is not accessed directly by the computer’s microprocessor. Examples include devices such as hard disks, optical discs, and magnetic tapes. Unlike random access memory, which the processor uses directly for temporary data storage during program execution, auxiliary storage holds data and programs for long-term retention. Because it provides permanent or semi-permanent storage, auxiliary storage is commonly referred to as secondary storage or permanent storage, while the memory accessed directly by the processor is known as main memory.

KembaraXtra-Computer Terms – avatar:
An avatar is a graphical representation used to represent a user in a virtual environment, such as online chat rooms, multiplayer games, or virtual reality spaces. The avatar serves as the user’s digital identity within the virtual environment and can take many forms, including a stylized human figure, a photograph or caricature of the user, an animated character, an animal, or even an object chosen by the user. Avatars allow users to interact visually with others in digital environments and often help personalize the user’s presence in online communities or virtual worlds.

KembaraXtra-Computer Terms – A/UX:
A/UX is a version of the UNIX operating system developed by Apple Computer for use on certain Macintosh computers. It is a multiuser and multitasking operating system based on AT&T System V Release 2.2 of UNIX, with additional enhancements designed to integrate Apple technologies. One of its key features is support for the Macintosh Toolbox, which allows applications running on A/UX to provide the graphical user interface typical of Macintosh systems. By combining UNIX capabilities with Macintosh graphical features, A/UX allowed users to run powerful UNIX-based applications while still benefiting from the familiar visual interface associated with Macintosh computers.

KembaraXtra-Computer Terms – awk:
awk is a programming language used in UNIX-based systems for processing and analyzing text files and data streams. It is particularly useful for tasks such as searching, filtering, and transforming data within files. The language forms part of the POSIX Command Language and Utilities standard and is widely used in shell scripting for handling structured text data. awk is considered simpler and more specialized than some other scripting languages, and it shares some functional similarities with PERL in its ability to manipulate and process text efficiently.

KembaraXtra-Computer Terms – background noise:
Background noise refers to the unwanted electrical or electronic signals that exist in a communication line or circuit even when no intended signal is being transmitted. This noise can interfere with or distort transmitted data or audio signals. Background noise is inherent in communication systems and may originate from environmental interference, electronic components, or transmission media. Reducing background noise is an important aspect of maintaining clear and reliable communication in electronic and networking systems.

KembaraXtra-Computer Terms – back-lit display or backlit display:
A back-lit display is a display surface that is illuminated from behind rather than from the front or above. The light source located behind the display panel spreads light across the surface so that images and characters appear bright and easy to read. This type of display technology is widely used in devices such as liquid crystal displays, laptop screens, and digital instruments where clear visibility is required regardless of external lighting conditions.

KembaraXtra-Computer Terms – background printing:
Background printing is a feature that allows a computer to send a document to a printer while continuing to perform other tasks simultaneously. Instead of waiting for the printing process to finish, the operating system handles the print job in the background, allowing the user to continue working on other applications or documents. This capability improves productivity by enabling multitasking and efficient use of system resources.

KembaraXtra-Computer Terms – background processing:
Background processing refers to the execution of certain tasks by an operating system or program while the main task is temporarily idle or awaiting user input. These operations occur without interrupting the user’s primary activity and are usually performed during short pauses in foreground processing. For example, a word processing program might print a document or save data automatically during the time intervals between user keystrokes. Background processing allows the system to perform multiple operations efficiently without affecting the user’s workflow.

KembaraXtra-Computer Terms – Back Orifice:
Back Orifice is a malicious software tool created to allow unauthorized remote control of a computer system. It operates using two main components: a client application used by the attacker and a server application installed on the target computer. Once the server component is installed—often through a deceptive executable file delivered via e-mail attachment or removable storage—the attacker can use the client program to control the infected system. The program typically installs itself in the system directory of the Windows operating system and allows remote commands to be executed on the compromised computer. First appearing in 1998, Back Orifice quickly became known as a security threat and prompted improvements in antivirus and security software. The name is a play on the Microsoft BackOffice server product suite.
