Your computer would stop working without an operating system, but there are alternatives to Windows, says Rick Maybury.
You can, but your computer would stop working because Windows is the operating system, the software that makes it tick and provides a platform for programs, like your web browser, to run on.
Can a computer run without hardware?
Most computers require at least a display, hard drive, keyboard, memory, motherboard, processor, power supply, and video card to properly function. If any of these devices are absent or faulty, an error is encountered, or the computer will not start.
What will happen if there is no operating system in a computer?
Without that, there is nothing left in memory. Still, your computer is not useless, because you can still install an operating system if the computer has external memory (long term), like a CD/DVD or a USB port for a USB flash drive. My current computer doesn’t have a hard disk, it has a solid state drive.
What does a computer need to run?
These are the necessary specifications your computer must have in order to use the software or hardware. For example, a computer game may require you computer to have Windows XP or later, a 2.0 GHz processor, 512 MB or RAM, a 64 MB graphics card, and 500 MB or hard drive space.
Do we really need antivirus?
If you’re running Windows, macOS/OS X or Android, you absolutely do need antivirus software. There’s no good reason not to have it: Many AV programs have little system-performance impact, and many good ones are free.
Will any hard drive work in my computer?
Any computer motherboard and hard drive that share a supported connection standard will work with each other. Motherboards that have Peripheral Component Interconnect and PCI Express expansion slots can use adapter cards to work with unsupported hard drives.
Do you need software for a PC?
Software is the backbone of any computer setup. Whether you’ve just purchased a new PC or reinstalled Windows, the first task you’ll likely do is install apps. While there are dozens of amazing Windows programs, knowing which are must-have software for Windows 10 makes setting up a new installation easy.
Why does my computer say operating system not found?
When a PC is booting, the BIOS tries to find a operating system on a hard drive to boot from. However, if it is unable to find one, then an “Operating system not found” error is displayed. It may be caused by an error in BIOS configuration, a faulty hard drive, or a damaged Master Boot Record.
Is operating system necessary for computer?
An operating system is the most essential program that allows a computer to run and execute programs. Without an operating system, a computer cannot be of any important use since the computer’s hardware won’t be able to communicate with the software.
