A computer is loading data when it is turned on and the operating system is being loaded.
operating system is not a loading, When is trun on system(press the power button). first of checked all the hardware devices,for exmple hard disk,ram,rom and etc. When the all devices dected process further. Jsb

AnswerAn operating system (OS) is software that controls the internals of a computer. The first large computers did not have operating systems or programming languages. You entered insructions through lights on the main console. The first operating systems were on punched cards, which you read into computer memory. They would then control instructions entered on decks of punched cards (a "computer program"). When you turned off the computer, the memory would NOT be cleared, so the next time you turned on the computer, the operating system would still be there. At this time, computers consisted of a "central processor" (the equivalent of a mother board today) that took up a room, punched cards input and output, and printers. There were no magnetic devices such as tapes or hard or floppy disk. The problem with this was that it required that everything from your operating system to your program be entered in "machine" language - binary codes that told the processor what to do (move something, compare something, add, subtract etc.). The next step was to create an operating system that was "flexible" and easily updated. So the "TOS", or Tape Operating System was created. This consisted of adding a tape drive to the computer complex, and storing the "OS" card deck on tape. About this time, they changed over to "volatile" memory that was cleared when you powered down the computer, so the OS had to be re-loaded every time when you turned it back on.In this way, if you wanted to change operating systems (go from a financial operating system that handled money to a scientific OS that handled spiral decay of satellites), you just stored that OS on a tape and mounted the tape you wanted, which you then loaded into memory. It was at this point that the "general purpose" computer was born. Up until then, each computer was dedicated to a task such as financial, or scientific or military.The computer then evolved into "magnetic" systems - tape, disk, cylinders, platters, CRAM (Card Random Access Memory) - there were many different kinds of storage that could be used for input and output. The next logical step was to take the TOS and put it out on disk (or even magnetic cards), so you didn't have to mount a tape to load or change an operating system. This was DOS (Disk Operating System). DOS was originally on mainframe computers.At the same time mainframe computers were maturing, so was the "hobby" computer. It followed the same path as mainfame, only slower, so it went through a "console lights" phase where you could only do something through the lights and/or switches, into an "operating system" on tape and finally into a DOS (of which there were several flavors). Today, most operating systems are DOS, but they might be stored on media other than disk, such as Thumb Drives, which are really solid state chips and not disk drives. The PC "BIOS", the Basic Input/Output Operating System, is an example of a DOS on a chip that is used to initialize your computer so it can read/write from all the devices that it consists of.
Need of Operating System:In earlier day's user had to design the application according to the internal structure of the hardware. Operating System was needed to enable the user to design the application without concerning the details of the computer's internal structure. In general the boundary between the hardware & software is transparent to the user.Usage of Operating System:Easy interaction between the human & computer.Starting computer operation automatically when power in turned on.Loading & scheduling users program.Controlling input & output.Controlling program execution.Managing use of main memory.Providing security to users program.

I'm pretty sure that's the POST or the Power On Self Test.

first the booting files are loaded in the RAM and these files are in the boot sector where operating system is installed . after loading these file then these files load the operating system in the RAM , some portion of RAM is Allocated by the OS. after that window is ready to perform tasks.

Booting up ..! A boot process is a step by step process with which a computer loads the operating system.
The bootstrap process is the sequence of actions that a computer system goes through when it is first turned on. It involves loading the operating system into memory and initializing the hardware components to prepare the system for use. The bootstrap process typically includes hardware diagnostics, configuration checks, and loading the necessary software components.

The computer's hard disk stores data - be that the operating system, application programs, documents or virtual memory.Stores data that needs to be kept between times when the computer is turned off.
"Boot up" is a phrase which refers to powering up a computer system. This is generally meant to include the loading of the operating system and any applications set to load on boot. "Cold booting" is booting up a computer which was previously turned off. "Warm booting" is restarting (and thus rebooting) a computer which was already running.
