Operating system is a piece of software. It resides on your Hard Drive. If you're a Windows user, it's on your C drive by default. When a computer is turned on, the ROM or BIOS activates the disk drives where it find the first piece of operating system : Bootstrap Loader . While your computer is turned on, the operating system is stored in _____ Files are stored in a hierarchial structure of _____ that includes files, folders, libraries, and drives.. The operator system is software- a program that controls the computer. It is usually stored on the hard drive when the computer is not running and is read into a special portion of main memory when..
The hard drive (sometimes called the hard disk) is the main storage device in your computer. Like RAM, it can be added to and changed, and like ROM it is non-volatile, but it is slow. If you have files and folders on your computer, are stored on the hard drive. The operating system is also stored on the hard drive The operating system is loaded through a bootstrapping process, more succinctly known as booting. A boot loader is a program whose task is to load a bigger program, such as the operating system. When you turn on a computer, its memory is usually uninitialized. Hence, there is nothing to run , it does not have an OS in memory - to load the operating system into memory, one needs to have an operating system already loaded into memor
When you turn on your computer it starts the Boot Process which tells the computer to go to the hard drive for the Operating System. A hard drive is a permanent storage device, so even when the computer is turned off the information will still be there. The operating system, program files, and all data files are stored on the hard drive Answer: (a) Accessories Explanation: The windows accessories are a group of programs in the operating system. Windows XP offers many accessories or software that you can use to help with your work. The accessories are not full features programs, but it is useful for a specific task in the operating systems The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on. If this file is not present, the computer cannot hibernate For example, the root folder of your system disk (C:\) contains system files such as the paging file (pagefile.sys) and the hibernation file (hiberfil.sys). Most system files of a Windows operating system are stored in the folder C:\Windows, especially in such subfolders as /System32 and /SysWOW64 When a computer is turned off, its software—including operating systems, application code, and data—remains stored on non-volatile memory. When the computer is powered on, it typically does not have an operating system or its loader in random-access memory (RAM)
Types of operating systems Single-tasking and multi-tasking. A single-tasking system can only run one program at a time, while a multi-tasking operating system allows more than one program to be running in concurrency.This is achieved by time-sharing, where the available processor time is divided between multiple processes.These processes are each interrupted repeatedly in time slices by a. When we turn on our computer installed operating system will start working. It ensures the co-ordination of other stored programs with system's hardware components.To enable operating system a Process is done which is called Booting. It is performed by a software stored in our system BIOS(basic input-output system). BIOS does the following functions When your computer is unable to boot to the operating system even after repeated attempts, it automatically starts SupportAssist OS Recovery. The recovery environment enables you to diagnose hardware issues, repair your computer, back up your files, or restore your computer to its factory state Your computer's bootloader is an important tool. It loads your computer's operating system when you turn the machine on. A bootloader toolkit, then, attacks this system, replacing your computer's legitimate bootloader with a hacked one. This means that this rootkit is activated even before your computer's operating system turns on. 3

This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions
Operating system(OS) is stored on the hard drive and controls the hardware. CPU is the brain of the computer and operating system is the brain of CPU which controls all the functionality of the computer. Without an operating system our machine is a simple hardware. The connectivity between hardware and and OS must be ensured for an effective. When the computer is turned on or restarted, it first performs the power-on-self-test, also known as POST. If the POST is successful and no issues are found, the bootstrap loader will load the operating system for the computer into memory.
