Answer 2

Answer:

1 - Input - process - output

2 - Operating system

3 - Disc defragmentation

Explanation:

1. Input-process-output:

• In systems analysis and software engineering, the input–process–output (IPO) model is a widely used approach for characterizing the structure of an information processing programme or another process.
• This is the most fundamental form for defining a process in many beginning programming and systems analysis texts.
• The input-process-output paradigm describes how a computer programme or any other type of process accepts inputs from a user or other source, does some computations on the inputs, and then returns the results of the computations.

The work is divided into three categories by the system:

• A legal requirement imposed by the environment (input)
• Based on the requirement, a calculation was made (process)
• Environmental considerations (output)  

2. Operating system:

• The actions and functions of hardware and software are coordinated by system software, which also regulates the operations of computer hardware.
• The operating system on a computer is an example of system software.
• Operating systems are software that controls the hardware of a computer and serve as a user interface for application programmes.
• Utility software, device drivers, and firmware are also included in system software.

3. Disc defragmentation:

• When files or fragments of data become dispersed across your discs, this is known as disc fragmentation.
• Not only do hard discs become fragmented, but removable storage can as well.
• This can result in poor disc performance and a general system slowdown.

Hence, IPO refers to input-process-output, operating system is an example of system software, rearranging the files can be done by disc defragmentation.
