A "Tasking" Operating System
Operating System's kernel
Technically they don't. They're just much much more useful with one. The operating system provides a means to run other programs and do basic housekeeping chores on the computer.A computer can be built to run without an operating system, instead executing a particular program at startup which then takes over control of the computer and handles everything internally. In fact, an operating system itself is just such a program, though one that can temporarily transfer (partial or complete) control over to other programs.
Yes, a computer operating system can be downloaded onto your computer. One of the most common file formats to download operating systems is the .img file format. The .img file format can be used by programs like Oracle's VirtualBox, to create a virtual computer on your own computer. This uses the operating system that is saved in the .img file without overriding your current computers operating system and basically creates another "fake" or virtual computer within your own computer. However, these operating systems can also be used to replace your current operating system or to dual boot your computer, this means to have two operating systems installed on one computer at the same time. Operating systems can also be downloaded for the sole purpose of replacing your current operating system. For example, when a person upgrades their computer from running Windows 8.1 to Windows 10, they are essentially downloading a new operating system on to their computer from Microsoft, but in a way that it completely replaces their current operating system.

Most people think of the operating system as the system software. The operating system is the most important software on a computer. It controls the computer's hardware and provides a platform for other software to run on. Operating systems are complex and often have a lot of low-level code that is difficult to understand. They also have to be very reliable, as a crash can mean lost data or even physical damage to the computer.
Run the Files and Settings Transfer Wizard under Accessories - System Tools.
The kernel is one of the primary nodes of an operating system for a computer. It contains operating system core functions and the device drivers.
The Operating System is located in a folder on one of the hard drives usually C:\. This is one \Windows\System32 and \Windows\winsxs. System32 is where the main operating system is but the manafest files are in winsxs.
Yes.
Any computer with the ability to understand "partitions" can run multiple operating systems, albeit one at a time. Any computer with the ability to run virtual hardware (such as with a Hypervisor) can run more than one operating system simultaneously. The operating system must also support partitions or it will be unable to run on a hard drive with more than one partition.
Yes, all computers need a set of instructions or program to tell it how to function. This what a operating system does for a computer.
