All i, ii, iii, iv and v. All of these are functions of an operating system.

i) Recovering from errors: An operating system is responsible for handling errors that occur in the system. This includes both hardware and software errors.

ii) Facilitating input/output: The operating system manages the communication between the user and the computer hardware. This includes managing input devices like the keyboard and mouse, and output devices like the monitor and printer.

iii) Facilitating parallel operation: Operating systems allow for multiple processes to be run at the same time. This is known as multitasking.

iv) Sharing hardware among users: In a multi-user system, the operating system manages the resources of the computer system so that multiple users can use the same hardware without interfering with each other.

v) Implementing user interface: The operating system provides a user interface that allows users to interact with the computer. This can be a graphical user interface (like Windows or MacOS) or a command-line interface (like Unix or Linux).
