KembaraXtra-Computer Terms – bandwidth management:
Bandwidth management is the process of monitoring, analyzing, and controlling network traffic to ensure efficient use of available bandwidth. It is commonly applied to wide area networks (WANs) and Internet connections where multiple users and applications compete for limited network resources.


By prioritizing certain types of traffic, bandwidth management helps improve the overall quality of service in a network. Critical applications such as video conferencing or business communications can be given higher priority to ensure stable performance even during periods of heavy network usage.

KembaraXtra-Computer Terms – bandwidth:
Bandwidth refers to the range of frequencies that a communication system can transmit. In analog communications, it is measured as the difference between the highest and lowest frequencies that a system can carry. For example, a telephone system typically supports a bandwidth of about 3000 Hertz, representing the range between approximately 300 Hz and 3300 Hz.


In digital communications, bandwidth refers to the data transfer capacity or transmission speed of a network or communication channel. It is commonly measured in bits per second (bps) and indicates how much data can be transmitted over a connection within a specific period of time.

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.

KembaraXtra-Computer Terms – band:
In computer printing and graphics processing, a band refers to a rectangular section of an image that is sent from a computer to a printer during the printing process. By dividing a large graphic into smaller sections called bands, the printer can process and print each portion sequentially instead of loading the entire image into memory at once.


In communication systems, the term band refers to a continuous range of frequencies used for transmitting signals. Different frequency bands are allocated for specific purposes such as radio broadcasting, television transmission, and wireless communication, allowing multiple communication services to operate without interfering with one another.

KembaraXtra-Computer Terms – balloons:
In document editing environments such as print layout or Web layout views, balloons are visual elements used to display markup information in the margins of a document. These balloons show details such as comments, suggested edits, or tracked changes made by reviewers during the editing process.


By placing these annotations in the margins rather than within the main text, balloons allow users to clearly see feedback and revisions without disrupting the original document layout. This feature makes it easier to review changes, respond to comments, and manage collaborative editing workflows.

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 track:
A bad track is a track on a hard disk or floppy disk that contains one or more faulty sectors. Because the track includes damaged areas that cannot reliably store data, the operating system identifies it as defective and prevents it from being used. By bypassing the bad track during data storage and retrieval operations, the system helps maintain data integrity and ensures that files are stored only in reliable areas of the disk.

KembaraXtra-Computer Terms – .bak:
A bak file is an auxiliary file that stores a previous version of a document or data file. It is typically created automatically by software applications or generated when a user explicitly chooses to create a backup version of a file. The file has the same name as the original file but uses the extension “.bak,” which indicates that it contains a backup copy of the data.


This type of file usually holds the second-most-recent version of a document so that the user can recover earlier content if the latest version becomes corrupted, accidentally deleted, or incorrectly modified. Many programs generate bak files as a safety mechanism to protect users from data loss and to allow easy restoration of earlier file versions.

KembaraXtra-Computer Terms – Balloon Help:
Balloon Help is an on-screen assistance feature originally developed for the Macintosh operating system by Apple Computer. The feature displays help information in the form of a cartoon-style dialog balloon that appears near items on the screen when the user requests assistance.


After activating Balloon Help by clicking the balloon icon in the system toolbar, users can move the cursor over interface elements such as icons, buttons, or menu items. A dialog balloon then appears, providing a brief explanation of the selected item’s function, helping users understand how to use different features of the operating system.
