Explanation
This statement is incorrect. ROM (Read-Only Memory) is a type of computer memory that is pre-programmed with data during manufacturing and cannot be modified or deleted by the user. It is non-volatile and retains its data even when the power is turned off. Therefore, we cannot write our own things or delete them in ROM.

Explanation
The statement is true because the operating system is typically stored in the hard disk of a computer. The hard disk is a non-volatile storage device that retains data even when the computer is turned off. The operating system is installed on the hard disk during the initial setup of the computer and is responsible for managing the computer's hardware and software resources. It provides the necessary interface for users to interact with the computer and runs various system processes in the background.

Explanation
It is possible to store more than one operating system on a computer by using techniques such as dual booting or virtualization. Dual booting allows the user to choose between different operating systems at startup, while virtualization enables running multiple operating systems simultaneously within a virtual environment. Therefore, the statement is incorrect and the correct answer is False.
