What is Operation of hardware?
The hardware architecture establishes the CPU instruction set and the type of operations that are permitted. It defines the passage of data from one part of the computer to another. It establishes the ground rules for input and output operations.
What are the main computer operations?
At a fundamental level, computers operate through these four functions: input, output, processing, and storage. Input: the transfer of information into the system (e.g., through a keyboard). Output: the presentation of information to the user (e.g., on a screen).

How does hardware protection work in an operating system?
Hardware Protection W hen executing in monitor mode, the operating system has unrestricted access to both monitor and user’s memory. The load instructions for the base and limit registers are privileged instructions.
What are the different types of hardware protection?
Basically, hardware protection is divided into 3 categories: CPU protection, Memory Protection, and I/O protection. These are explained as following below. CPU protection is referred to as we can not give CPU to a process forever, it should be for some limited time otherwise other processes will not get the chance to execute the process.
How does the operating system work in monitor mode?
When executing in monitor mode, the operating system has unrestricted access to both monitor and user’s memory. The load instructions for the base and limit registers are privileged instructions. Timer – interrupts computer after specified period to ensure operating system maintains control. Timer is decremented every clock tick.
What does it mean to have CPU protection?
CPU protection is referred to as we can not give CPU to a process forever, it should be for some limited time otherwise other processes will not get the chance to execute the process.
