KembaraXtra-Computer Terms – ATM:
ATM can refer to two different technologies. The first meaning is Asynchronous Transfer Mode, a high-speed network technology capable of transmitting different types of data such as voice, video, audio, and traditional data traffic in real time. In ATM networks, data is divided into fixed-size packets called cells, each containing 53 bytes—5 bytes of routing information and 48 bytes of actual data. These cells are transmitted across the network at speeds ranging from 1.5 Mbps to 622 Mbps and are reassembled at the destination. ATM technology supports efficient use of network resources by allowing cells from different users to be transmitted asynchronously.


The second meaning of ATM is Automated Teller Machine, a specialized banking terminal that allows customers to perform financial transactions such as withdrawing cash, depositing money, or checking account balances without the need for a bank teller.

KembaraXtra-Computer Terms – ATM Adaptation Layer:
The ATM Adaptation Layer is the layer in an Asynchronous Transfer Mode network that acts as an intermediary between higher-level network services and lower-level ATM transmission processes. It converts different forms of data—such as audio, video, and data frames—into the fixed 48-byte payload format required for ATM cells.

KembaraXtra-Computer Terms – ATM Forum:
The ATM Forum is an industry organization established in 1991 that includes hundreds of companies involved in communications and computing, along with government agencies and research institutions. Its purpose is to promote the development, standardization, and adoption of Asynchronous Transfer Mode technology for data communication.

KembaraXtra-Computer Terms – atomic operation:
An atomic operation is a process that is considered indivisible, meaning it cannot be interrupted while it is being executed. If the operation is aborted before completion, a recovery mechanism restores the system to its original state before the operation began.

KembaraXtra-Computer Terms – atomic transaction:
An atomic transaction is a group of operations that follow the “all or nothing” rule. Either all operations are completed successfully or none of them take effect. This approach is commonly used in systems such as financial transfers or order processing to ensure that data remains consistent. If any part of the transaction fails, the entire transaction is cancelled and the system returns to its previous state.

KembaraXtra-Computer Terms – attach:
Attach means to include an external file, document, or executable program with an e-mail message so that it can be sent to the recipient along with the message.

KembaraXtra-Computer Terms – attached document:
An attached document is a file included with an e-mail message as an attachment. It may be an ASCII text file or a binary file such as a word-processing document, and it is typically encoded using formats that allow it to be transmitted through e-mail systems.

KembaraXtra-Computer Terms – attached processor:
An attached processor is a secondary processor connected to a computer system to assist with specific tasks. Examples include processors used in keyboard controllers or video subsystems that handle specialized processing separate from the main CPU.

KembaraXtra-Computer Terms – attachment:
An attachment is a file that is sent together with an e-mail message. The attached file is an exact copy of the original file stored on the sender’s computer and can include many different types of files such as documents, executable programs, images, or compressed archives containing multiple files. Although it accompanies the e-mail message, the attachment itself is not part of the actual message text. To allow the file to be transmitted through e-mail systems, it is typically encoded using formats such as uuencoding, MIME, or BinHex. Most modern e-mail applications automatically encode files before sending them and decode them when they are received. The recipient must use an e-mail program capable of decoding the file or a separate decoding utility in order to open and read it. Some e-mail systems or gateways may restrict attachments based on file size, but most allow multiple files to be attached to a single e-mail message.

KembaraXtra-Computer Terms – attenuation:
Attenuation refers to the gradual weakening or reduction in strength of a signal as it travels through a transmission medium. This weakening can occur with different types of signals, including digital data signals and electrical signals, and may result in distortion or reduced amplitude by the time the signal reaches its destination. Attenuation commonly occurs in communication systems such as telephone lines, network cables, and wireless transmissions, where signal strength naturally decreases with distance from the source. It is usually measured in decibels (dB). In some situations attenuation is undesirable because it can reduce signal quality and cause errors in data transmission. However, it can also be intentionally applied in electronic systems—for example, using a volume control on a radio to reduce signal strength and prevent overloading or distortion.
