Utilities-Hardware:
Computer hardware is the physical part of a
computer, as distinguished from the computer
software or computer programs and data that
operate within the hardware. The hardware of
a computer is infrequently changed, in comparison
with software and data which are "soft"
in the sense that they are readily created,
modified or erased on the computer. Firmware
is special software that rarely, if ever, needs
to be changed and so is stored on hardware devices
such as read-only memory (ROM) where it is not
readily changed (and therefore is "firm"
rather than just "soft"). Most computer
hardware is not seen by normal users as it is
enclosed as embedded systems in automobiles,
microwave ovens, electrocardiograph machines,
compact disc players, and many other household
appliances. For Instance CPUs provide the fundamental
digital computer trait of programmability, and
are one of the core components found in almost
all modern microcomputers, along with primary
storage and input/output facilities. A CPU that
is manufactured using integrated circuits, often
just one, is known as a microprocessor. |
