KembaraXtra-Computer Terms – black box:
A black box refers to a hardware or software component whose internal workings are not visible or necessary for the user to understand. Although the internal structure remains hidden, the function of the component is clearly defined and documented.
Designers and engineers often use black boxes as functional units within larger systems. For example, a memory chip can be treated as a black box because users only need to know how it stores and retrieves data, not the detailed internal processes that make it work.

KembaraXtra-Computer Terms – black box testing:
Black box testing is a software testing method in which the tester evaluates a program solely based on its functionality. The internal code and structure of the program are not examined; instead, the focus is on verifying that the software produces the correct outputs for given inputs.
This approach reflects the perspective of an end user, emphasizing whether the software behaves as expected rather than how it is built. Black box testing is commonly applied during the development process to identify functional errors or usability issues.

KembaraXtra-Computer Terms – black hat:
A black hat is a type of hacker who engages in unauthorized activities with harmful or criminal intent. Such individuals typically attempt to break into computer systems in order to steal information, damage data, or disrupt services.
The term distinguishes malicious hackers from ethical hackers, often referred to as white hats, who test systems to improve security. Black hats exploit vulnerabilities in systems for personal gain or malicious purposes.

KembaraXtra-Computer Terms – black hole:
In networking terminology, a black hole refers to a location within a computer network where messages or data disappear without explanation. Information sent to this location fails to reach its destination and cannot be recovered or traced easily.
The name is derived from the astronomical phenomenon known as a black hole, where gravitational forces are so strong that even light cannot escape. In computing, the term may also be used informally to describe projects or tasks that consume large amounts of time and resources without producing meaningful results.

KembaraXtra-Computer Terms – blackout:
A blackout is a situation in which electrical power drops completely to zero, resulting in a total loss of electricity. Such events can occur due to natural disasters like storms or earthquakes, or because of technical failures in power infrastructure such as damaged transformers or broken power lines.
For computers, a blackout can be harmful depending on what the system was doing when the power was lost. Any unsaved data will be lost immediately, and if the blackout happens while a disk is reading or writing data, files may become corrupted or even lost entirely. In some cases, hardware damage can also occur. To protect systems from these risks, a battery-backed uninterruptible power supply (UPS) is often used.

KembaraXtra-Computer Terms – blank:
In computing, a blank refers to the space character that is produced when the spacebar is pressed on a keyboard. This character does not display a visible symbol but creates a space between words or elements in text.
Although it appears empty, the blank space is still a valid character in digital text. It plays an important role in formatting, separating words, and maintaining readability within documents and computer programs.

KembaraXtra-Computer Terms – blip:
A blip is a small mark or signal detected optically on a recording medium such as microfilm. These marks are used to assist with counting, indexing, or tracking information within stored records.
Blips allow systems to identify positions or sections within a sequence of recorded data. By detecting these marks, equipment can quickly locate specific portions of stored information.

KembaraXtra-Computer Terms – blind search:
Blind search is a method of searching for information in memory or on a storage device without any prior knowledge of where the data is located or how it is organized. The system simply checks each possible location until the desired data is found.
Because it does not rely on indexing or ordered data structures, blind search can be slower than more efficient search methods. It is often associated with simple search techniques such as linear searching.

KembaraXtra-Computer Terms – blink:
To blink in computing means for a display element to flash repeatedly between visible and invisible states. This visual effect is often used to attract the user’s attention to a particular item on the screen.
Elements such as text cursors, insertion points, warning messages, or menu selections may blink to indicate activity or highlight important information. In many graphical user interfaces, the blinking behavior can be adjusted by the user.

KembaraXtra-Computer Terms – blanking:
Blanking refers to the temporary suppression of the display signal in a raster-scan video monitor while the electron beam repositions itself to draw the next line or frame of the image. During normal display operation, the beam scans across the screen line by line to form the image.
After finishing each horizontal line, the beam must move back to the left side of the screen to begin the next line. During this movement, called horizontal retrace, the display signal is turned off to prevent unwanted marks. Similarly, after the final line at the bottom of the screen is drawn, the beam returns to the top left corner during vertical retrace, and the signal is again suppressed to maintain a clean display.
