KembaraXtra-Computer Terms – backward chaining:
Backward chaining is a reasoning method used in expert systems and artificial intelligence for solving problems and drawing conclusions. The process begins with a goal or statement that needs to be verified and then works backward through a set of rules that could lead to that conclusion. The system checks whether the conditions required by each rule can be satisfied using information stored in a database of known facts. By repeatedly matching rules with available data, the system determines whether the original statement can be confirmed or disproved. Backward chaining is often used in rule-based systems where conclusions are derived by analyzing possible causes or supporting evidence.

KembaraXtra-Computer Terms – bad sector:
A bad sector is a damaged or unusable sector on a disk storage device where data cannot be stored reliably. The damage may be caused by physical imperfections in the disk surface, manufacturing defects, or wear over time. Operating systems and disk utilities often include tools that scan disks to detect bad sectors. When such sectors are identified, they are marked so the system avoids storing data in those locations, helping protect data from corruption or loss.

KembaraXtra-Computer Terms – bad block:
A bad block is a defective location in a storage medium or memory device that cannot reliably store or retrieve data. When a computer system starts up or performs a diagnostic check, the memory controller may identify these faulty areas during a self-test procedure. Once detected, the system marks the bad block so that it is not used for storing data. Avoiding these defective areas helps prevent data corruption and ensures the reliability of the storage system.

KembaraXtra-Computer Terms – BAD:
BAD is an acronym for “broken as designed,” a slang term used in computing and engineering contexts to criticize a product or device that consistently fails to function properly even though it technically operates according to its design. The term is typically used humorously or sarcastically to suggest that the design itself is flawed and that the product’s failures are a direct result of poor design decisions rather than accidental defects.

KembaraXtra-Computer Terms – bacterium:
In computing, bacterium refers to a type of malicious program similar to a computer virus that continuously replicates itself within a system. As the program duplicates repeatedly, it consumes increasing amounts of system resources such as memory and processing power. Over time, this uncontrolled replication can overwhelm the system and disrupt normal operation, eventually causing system slowdown or failure. The behavior resembles the rapid reproduction of biological bacteria, which is why the term bacterium is used to describe this type of destructive software.

KembaraXtra-Computer Terms – Backspace key:
The Backspace key is a key on computer keyboards used to move the cursor one position to the left, typically deleting the character immediately to the left of the cursor as it moves. On IBM-compatible keyboards, pressing the Backspace key repeatedly deletes characters one at a time while moving the cursor backward through the text. On Macintosh keyboards, a similar function is provided by the Delete key on some models. In this case, the key either removes selected text or deletes the character located to the left of the insertion point when no text is selected.

KembaraXtra-Computer Terms – backtracking:
Backtracking is a problem-solving technique used in expert systems and certain algorithms that allows the system to explore different possible solutions when attempting to find an answer. The method works by examining one possible solution path at a time, much like following branches on a tree. If the system reaches a point where the current path does not lead to a correct or complete solution, it retraces its steps to a previous point and attempts another alternative path. This systematic trial-and-error approach enables the program to explore multiple possibilities until it finds a valid solution or determines that no solution exists.

KembaraXtra-Computer Terms – backup and restore:
Backup and restore refers to the overall process of maintaining backup copies of files or systems and restoring those copies when needed. The backup stage involves regularly creating duplicate copies of important data and storing them safely. The restore stage occurs when the original data is lost, damaged, or corrupted, requiring the stored backup files to be copied back onto the original storage medium or another location. This process ensures that systems and data can be recovered quickly after unexpected failures or data loss events.

KembaraXtra-Computer Terms – Backus–Naur form:
Backus–Naur form is a metalanguage used to formally describe the syntax of programming languages and other formal languages. It provides a structured way to define how language elements are constructed and combined. In Backus–Naur form, the syntax of a language is described using a series of rules. Each rule defines a language component called a metavariable, which is typically written inside angle brackets, in terms of actual symbols known as terminals and other metavariables. These definitions allow both language designers and users to understand how valid statements in the language should be structured. Backus–Naur form is widely used in computer science for specifying the grammar of programming languages and compilers.
