Answer
Computer hardware is
any physical device, something that you are able to touch and
software is a collection of
instructions and code installed into the computer and cannot be touched. For example, the computer
monitor you are using to read this text on
and the mouse you are using to navigate
this web page is computer hardware. The
Internet browser that allowed you to visit this page and the
operating system that the browser is
running on is software.
Can
a computer run without software?
In most situations, yes, a computer can run without software
being installed. However, if an operating system or interpreter is not found
on the computer it would either generate an error or sit at a black screen.
Installing additional programs onto the computer after the operating system
has been installed will only give that computer additional abilities. For
example, a word processor is not required, but will allow you to create
documents and letters.
Can a computer run without hardware?
Depends
on the hardware. Almost all computer setups will require at least a disk
drive (e.g. hard drive),
display,
keyboard,
memory,
motherboard,
processor,
power supply, and video card in
order to function properly. If any of these devices was missing or had
problems, an error would be encountered, or the computer would not start.
Adding other hardware such as a disc drive (e.g.
CD-ROM or
DVD), modem,
mouse,
network card, printer,
sound card,
speakers, etc. are not required, but
will give the computer additional capabilities.Additional information
