RAM: as without it, other internal hardware


is one of the main components of the computer as it connects to all parts of
the computer. It can also be called as a backbone of the computer. Mother board
has the ports for CPU, RAM, Power supply, sound and graphic card etc. for easy
operation of the user.

? Central processing Unit (CPU):

CPU is an electronic component inside a computer
that basically receives commands from the software and transfers the
information to the other components of the computer. It also denotes how fast a
computer can operate. The design, form and implementation of CPUs have changed over the period of
time, but their basic job remains the same.

? Power
Supply Unit:


Power supply is a piece of hardware that facilitates in conversion of power
provided from outside into power that can be used by many parts inside the
computer. It also controls voltage
by regulating overheating. Power supply is one of
the essential hardware components in a computer as without it, other internal
hardware won’t function properly.


BIOS stands for basic input/output system, this is the first thing one actually
sees when they turn on their computer. It’s a software that comes in the computer that initializes the
hardware before booting an operating system from a hard-drive or any other
drive. Following functions can be performed by the users using BIOS:


Let us understand the computer hardware components essentially required to use
the computer in detail:



? What are desktops, laptops and servers?

A desktop computer is a computer which is meant
to be kept on a desk and is not portable. A desktop comes in several components
that are connected to each other such CPU, RAM, motherboard etc. These devices
connect directly with a power source instead of working on a battery.
A laptop on the contrary is portable in nature and can operate on a battery for
a few hours. It is relatively convenient to use than a desktop, however
for high power-consumptions tasks, desktops are preferred over laptops.
A server is a computer, a
device or a program that is dedicated to managing network resources. Servers
are often referred to as dedicated because they carry out hardly any other
tasks apart from their server tasks. There are a number of categories of
servers, including print servers, file servers, network servers and database
servers. In theory, whenever computers share resources with client machines
they are considered servers.


? What
is a computer?

The word computer is derived
from a Latin word ‘computare’ which means ‘to calculate’. It is basically an
electronic machine that can solve different problems, process, store and retrieve
data and perform calculations faster than humans. There are several types of
computers such as desktops, laptops and server systems. Different types of computers are used by different people and
organizations depending upon their usage. For example, servers are generally
found in businesses rather than houses as they have to manage many computers at
a time.                                                                                                                                                                                                                                                                  

who are really serious about software, should make their own hardware”

is hardware required?

There may be plenty of reasons
why hardware is important however the biggest reason amongst all is that,
software can only be utilized through hardware. Without software, hardware
might not be that appealing but it would somehow work. Another important use of
hardware is that, owning the hardware, facilitates in providing seamless user
experience. For instance, biggest reason for Apple products to be so popular,
is their phenomenal user experience. Apple is able to provide such experience
because it makes its own hardware and software unlike the competitors which is
also known as, Vertical Integration Strategy.

is hardware?

Hardware is a generic term used for tools, equipment or their components used
for a specific purpose. Hardware is tangible in nature and can be of several
types, for example: 1) Computer hardware like Central Processing Unit, BIOS,
Motherboard, Random Access memory etc. 2) Input device Peripherals like a mouse
or a keyboard, output device peripherals like a monitor or a scanner and lastly
storage device peripherals like hard drive. 3) PLCs i.e. programmable logic
controller. 4) Mobile devices like cell phones, tablets, personal digital
assistant (PDA), smartwatch, Bluetooth handset etc. 5) Networking devices like
routers, ethernet cables, repeater, modems etc.
