usually connected to a computer or media player that displays digital images,
videos, or interactive content.
· Digital signage
displays can be found in a variety of settings, including shopping malls,
airports, banks, and retail stores.
· They are commonly
used to display real-time information, such as weather and news updates, as
well as advertising and promotional messages.
What is Central Processing Unit (CPU)
The Central Processing Unit (CPU) is the primary component of a
computer that performs most of the processing tasks.
It is often referred to as the "brain" of the computer,
as it manages and executes the majority of software operations. The CPU
retrieves and executes instructions from memory and performs basic
arithmetic, logic, and input/output operations.
· It communicates
with other components in the computer, such as memory and input/output devices,
to complete tasks.
· The CPU is
typically composed of multiple cores and is an integrated component of the
computer's motherboard.
What is Software
Software is a set of computer programs and related data that
provide the instructions for telling a computer what to do and how to do it.
· It is a type of
digital product that provides the necessary instructions to interact with and
control hardware components, such as a computer's central processing unit,
memory, and input/output devices.
· Examples of software
include operating systems, application software, and system utilities. Software
can be pre-installed on a device or purchased and installed by the user.
