What is the definition of atomicity in computer science and how does it relate to transaction processing?
Atomicity in computer science refers to the property of a transaction being indivisible and either fully completed or not completed at all. In transaction processing, atomicity ensures that all operations within a transaction are either all successful or all rolled back in case of failure, maintaining data consistency.

Whys sanitize live computer transactions?
Test data will be representative of live processing;It is unlikely that all transaction types or error conditions will be tested in this way.
What is the advanced definition of computer?
A computer is an electro-mechanical programmable machine which is capable or receiving data (input), processing that data, and finally giving it out as reasonable information (output).
The result of the computer processing your input is referred to as?
The result of a computer's processing is known as "output."
What on a computer displays the results of processing?
Any output device can do this. A monitor, a printer, or even speakers. Speakers might not "display" information, but their output is a result of processing as you put it.

What exactly does a Transaction Processing System do?
A Transaction Processing System is a computer software system that allows an individual or business to process transactions. One can take payments for tickets or items this way.
What is a computer based information system that keeps track of their transactions?
Transaction processing system (TPS)
What is the definition of formatting?
the definition for formatting is: the organization of information according to preset specifications (usually for computer processing)
What is transaction processing cycle?
TPS or Transaction Processing Monitor is a set of information which process the data transaction in a database system that monitors transaction programmes. It manages the data that must be left in a consistent state. Transaction processing is a type of computer processing that takes place in the presence of a computer user. It allows for an immediate response to a user request (or transaction). Examples of such systems would be Airline Reservation Systems, Banking Systems, or the Accounting System of almost any large company. Standard transaction-processing software, notably IBM's Information Management System, was first developed in the 1960s. It ensures the ability to develop applications in a single-user mode.
Where can one find the definition of digital computer?
The definition of digital computer can be found listed on nearly any dictionary website such as TheFreeDictionary. The definition is really rather basic in that a digital computer is simply a device for processing information.
What is the definition of processing devices?
Processing devices are those devices which are used for processing the computer system. For example:mother board, video card,sound card etc.

What is transaction processing in dbms?
Transaction processing is information processing that is divided into individual, indivisible operations, called transactions. Each transaction must succeed or fail as a complete unit; it cannot remain in an intermediate state. Transaction mandatorily requires acknowledgment to get received as a necessary feedback for accomplishment.Transaction processing is designed to maintain a computer system (typically a database or some modern filesystems) in a known, consistent state, by ensuring that any operations carried out on the system that are interdependent are either all completed successfully or all canceled successfully.For example, consider a typical banking transaction that involves moving $700 from a customer's savings account to a customer's checking account. This transaction is a single operation in the eyes of the bank, but it involves at least two separate operations in computer terms: debiting the savings account by $700, and crediting the checking account by $700. If the debit operation succeeds but the credit does not (or vice versa), the books of the bank will not balance at the end of the day. There must therefore be a way to ensure that either both operations succeed or both fail, so that there is never any inconsistency in the bank's database as a whole. Transaction processing is designed to provide this.Transaction processing allows multiple individual operations to be linked together automatically as a single, indivisible transaction. The transaction-processing system ensures that either all operations in a transaction are completed without error, or none of them are. If some of the operations are completed but errors occur when the others are attempted, the transaction-processing system "rolls back" all of the operations of the transaction (including the successful ones), thereby erasing all traces of the transaction and restoring the system to the consistent, known state that it was in before processing of the transaction began. If all operations of a transaction are completed successfully, the transaction is committed by the system, and all changes to the database are made permanent; the transaction cannot be rolled back once this is done.Transaction processing guards against hardware and software errors that might leave a transaction partially completed, with the system left in an unknown, inconsistent state. If the computer system crashes in the middle of a transaction, the transaction processing system guarantees that all operations in any uncommitted (i.e., not completely processed) transactions are cancelled.Transactions are processed in a strict chronological order. If transaction n+1 intends to touch the same portion of the database as transaction n, transaction n+1 does not begin until transaction n is committed. Before any transaction is committed, all other transactions affecting the same part of the system must also be committed; there can be no "holes" in the sequence of preceding transactions.
