🔵 Batch processing would be used if you had collected a very large amount of data offline and need to now process it all in one go
🔵 Transaction file of hours worked is kept
🔵 Master file of workers details/rate of pay per hour
🔵 Transaction file is used with master file to update master file/produce
payslips
🔵 Jobs are set up so they can be run to completion without human interaction
🔵 The input data are collected into batches and each batch is processed as a
whole
🔵 Batch processing can occur when the computing resources are less busy
🔵 Batches can be stored up during working hours and then executed during
the evening/whenever the computer is idle
🔵 Batch processing is particularly useful for operations that require the
computer or a peripheral device for an extended period of time
🔴Real-time processing would be suitable for controlling the rockets
🔴Real-time processing causes a response within specified time constraints
🔴Real-time responses are in the order of milliseconds, and sometimes
microseconds
🔴Real-time means that the inputs are processed and produce an output
which in turn affects the input
🔴Controlling rockets often involves the use of sensors and control systems
🔴A computer system used for real-time processing is often used 24 hours a
day for the same task
🔴Real-time data processing gives the scientists the ability to take immediate
action for those times when acting within seconds is significant
🔴If a rocket is off course for just a short period of time its speed is such it
would be off course by a large distance
🔴If the rocket veers off course the computer would immediately fire engines to
correct it.
