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.

KembaraXtra-Computer Terms – backplane:
A backplane is a circuit board or structural framework designed to support multiple electronic components and circuit boards within a computer system. It provides the electrical connections that allow these components to communicate with each other and receive power. In many systems, expansion cards or modules plug into slots connected to the backplane, which distributes power and data signals among the installed devices. Backplanes are commonly used in servers, large computer systems, and industrial equipment where multiple boards must be interconnected efficiently.

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 – back up:
Back up refers to the process of creating a duplicate copy of a program, disk, or data so that it can be restored if the original is lost, damaged, or corrupted. This duplicate copy serves as protection against data loss caused by hardware failures, software errors, or accidental deletion. In another context, to back up may also mean returning a system or database to a previously known stable state where the information is complete and consistent. This restoration helps ensure that systems can recover from errors without losing critical data.

KembaraXtra-Computer Terms – backup:
A backup is a duplicate copy of data, programs, or entire storage devices created to protect important information from accidental loss or damage. Backup copies are typically stored on separate storage media or locations so that the information can be recovered if the original files become corrupted, deleted, or destroyed. Many software applications automatically create backup versions of files to maintain both the current version and a previous version of the data. These copies act as a form of insurance, ensuring that valuable information can be restored if necessary.

KembaraXtra-Computer Terms – backup and recovery:
Backup and recovery is a strategy used in database management systems to restore a database to a consistent and usable state after it has been affected by a system failure, software error, or hardware malfunction. The process begins by restoring the most recent backup copy of the database. After the backup is restored, the system reads the transaction log or change file that records all database operations performed since the backup was created. By replaying these logged transactions up to the most recent checkpoint, the system reconstructs the database so that it reflects the latest complete and consistent state before the failure occurred.

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.

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.
