TEXT 1
HARDWARE REQUIREMENTS
All computer software needs certain hardware components or
other software resources to be present on a computer. These
prerequisites are known as (computer) system requirements and are
often used as a guideline as opposed to an absolute rule. Most
software defines two sets of system requirements: minimum and
recommended.
The most common set of requirements defined by any
operating system or software application is the physical computer
resources, also known as hardware. A hardware requirements list is
often accompanied by a hardware compatibility list (HCL),
especially in case of operating systems. An HCL lists tested,
compatible, and sometimes incompatible hardware devices for a
particular operating system or application.
Architecture
All computer operating systems are designed for a particular
computer architecture. Most software applications are limited to
particular operating systems running on particular architectures.
