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:
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 – 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 – 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 – 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 – 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 – back panel:
The back panel is the rear section of a computer case or cabinet where external connections are made. This panel typically contains ports and connectors used to attach peripherals and external devices such as keyboards, monitors, printers, network cables, audio devices, and power supplies. Because most external connections are located at the back of the computer, the back panel serves as the primary interface between the internal components of the computer and external equipment.

KembaraXtra-Computer Terms – bandwidth reservation:
Bandwidth reservation is the process of allocating a specific portion of network bandwidth in advance for particular users, applications, or services. This ensures that important data transmissions receive sufficient network resources when they are needed.
By reserving bandwidth for time-sensitive applications, such as voice communication or real-time video, networks can maintain stable performance and reduce delays. This technique helps optimize network traffic and ensures that high-priority data packets are delivered efficiently.

KembaraXtra-Computer Terms – bandpass filter:
A bandpass filter is an electronic circuit designed to allow signals within a specific frequency range to pass through while blocking or reducing signals outside that range. The selected range of frequencies that the filter allows to pass is known as the passband.
Signals with frequencies higher or lower than this defined band are either attenuated or completely blocked. Bandpass filters are commonly used in communication systems, audio equipment, and radio technologies to isolate useful signals and reduce unwanted noise or interference.
