    The operating is designed to let the CPU deal with one thing at a time, allowing it to multitask. Without an operating system using and enforcing a standard, systematic approach to running the computer, you're put in the position of writing code (or programs) that must tell the computer exactly what to do.

      Which means it is still "booted up" without an OS.

    No.

    Boot, in computer terms, is defined as starting the operating system so without an OS, there is nothing to boot.

    The bootup process is preceded by the BIOS (or rather the bootup process starts with the BIOS). Starting the BIOS isn't necessarily booting. It just "wakes" the hardware and do a lot of self-checks. As for devices and gadgets like your car or a microwave oven, they do have "simpler" operating systems installed in them and they boot "quickly" once plugged in. You just don't see the familiar BIOS and OS screens.

    No, the best it will do is POST (power on self test) and/or if you hit the correct key during the splash screen (ususally "delete") it will take you into the BIOS (basic input/output system) but it will not completely "boot" which is the process of loading the OS and getting the computer ready for use.

    - you will only get as far as a black screen that says something along the lines of "unable to boot" or "no bootable device found" which means no OS was found or that the Boot sector of the OS is corrupt.

    Yes. I just built a new pc and just wanted to test the motherboard, cpu and ram, so it booted directly into the bios. Also I work with microprocessors that have no os and simply boot to run a single program. Computers always need instructions, but not necessarily a whole operating "system" to run those instructions. An operating system is nothing more than a program itself that can run other programs from within. It is a convenient platform in which to add drivers that allow communications with other hardware as well as a convenient way to start and stop multiple programs.

    Because your question is pretty vague, you can see the various answers you're getting. Perhaps you should update your question and tell us WHY you're asking? You may get more specific results that way.

    Unless you want to run a server, I suppose it can.

    Yes. The computer in your car, in your refrigerator, in your microwave, they boot up when power is applied, and they go right into their program. No OS necessary.

      This is the Desktop category Einstein, not the car or small appliance categories....and even most of those have some kind of operating system in them to tell them what to.
