Answer 2

Answer:

Transaction

A transaction is a logical unit of database processing that includes one or more database access operations such as an insertion, deletion, modification, and retrieval. Instructions are always atomic in nature i.e. either an instruction execute completely or it does not execute at all.

But it is possible to have partially executed programs which means some instructions are executed but some are not. According to the user either a work is done or not done therefore a transaction is that of instructions which perform a logical unit of work.
