Computer System
All of the electronic
and mechanical
equipment in a
computer is called
HARDWARE
refers to the
physical elements of a
computer. Also referred
to as the machinery or
the equipment of the
computer.
HARDWARE
is a set
of instructions, data
or programs used to
operate computers
and execute specific
tasks.
SOFTWARE
is a
generic term used to
refer to applications,
scripts and programs
that run on a device.
SOFTWARE
is used to describe
computer programs
that perform a task
or tasks on a
computer system.
SOFTWARE
A computer’s main board is its printed
circuit board and its foundation. It handles
the flow of electricity and data to and from
the central processing unit, the random
access memory, and the rest of the
computer’s hardware.
MOTHERBOARD
Is a medium for permanently storing
information. The term “non-volatile” is
used to describe data storage media that
doesn’t lose its contents when the power
is cut. simply one kind of storage device that
computers use.
HARD DISK
Is a key factor that affects the efficiency
of your system. provides a temporary storage
location for running programs. It keeps
data that is currently being used by your
computer in a place where it may be
accessed quickly
RAM
Is a part that powers one or more electric
loads. While its primary function is to
transform one source of electrical power
into another, it can also be used to change
other forms of energy (such as solar,
mechanical, or chemical) into electricity.
POWER SUPPLY
Refers to the hardware in a computer
that interprets and acts upon the
fundamental instructions that keep the
machine running. As the central processing
unit (CPU) processes and executes most of
the computer’s instructions, it is widely
considered to be the most important and
central IC chip in the device
PROCESSOR
Protects a computer’s (or another
electronic device’s) pricey but essential
components. Everything from the
motherboard, chassis, disks, CPU, and more
in a modest desktop device to an entire
network and even complex blade servers
are internal components.
CASE
Hardware that, when attached to a
computer, renders the latter’s output
in the form of visible video and
images.
MONITOR
are one of the most common types
of input devices for computers. much like an electric typewriter, is made up of
buttons that are used to input text (including
letters, numbers, and symbols) and perform
other actions.
KEYBOARD
Is a portable hardware input device used
to direct the movement of a cursor in a
GUI (graphical user interface) and make
selections of on-screen elements like text,
icons, files, and folders.
MOUSE
Is a Programming code that is performed on computer hardware
and helps a computer carry out tasks is referred to as computer. it is made up of programs that communicate with
the computer via programming code.
