Partitioning in reference to operating systems - Computer architecture and design

What do you understand by partitioning in reference to operating systems. Give their advantages and disadvantages.

- Partitioning involves the user to partition their hard drives and then they can implement / install multiple operating systems on them. The user requires a boot manager to switch between different operating systems.

- Partitioning allows each operating system to work optimally.

- Each os has the complete access to the hardware of the system on which it is being executed.

- Also depending on the file system used the user is free to resize his partition according to his needs.

- But manual partition is not a simple task and requires patience.

- The system needs to be restarted in case the user wants to switch operating systems.
