Answer Posted / sud
A transaction is a unit of processing that consists of one
or more application programs. A transaction is initiated by
a single request, often from a terminal, usually using a
four-character transaction identifier. A transaction might
require the initiation of one or more tasks for its
execution.
A task is a single instance of the execution of a
transaction. CICS, in conjunction with the operating
system, manages the control of multiple tasks by allocating
a system process to each task. While one task is waiting
(for example, to read a file or to get a response from a
terminal), the operating system can give control to another
task.
