Difference between Hardware and Software

A computer system (also called a desktop) is usually classified into two
sections, namely hardware and software. Both these sections are necessary
for the computer system to run properly. Although both the terms seem to be
similar,

there are significant differences between hardware and software

.

Before we compare hardware and software, let us first understand both with
their brief definitions:

What is Hardware?

Hardware refers to the physical devices or components that are physically
connected to the computer. Hardware devices are tangible and help to set up
a computer system. Hardware alone cannot function to serve the purpose. They
are connected together to function properly. Input devices, output devices,
storage devices, processing devices, and other internal components are
examples of hardware in a computer system.

internal

and

external

hardware, depending on
whether we can directly or indirectly see and touch such devices. For
example,

Some hardware devices can be touched and seen directly, while others are assembled inside the computer case (called the CPU in general; however, it’s not). Hardware devices or components are usually classified intoandhardware, depending on whether we can directly or indirectly see and touch such devices. For example, RAM is internal hardware while the keyboard is external hardware.

What is Software?

Software refers to a collection of data, instructions, programs, or rules
that instruct a computer system or electronic components to work efficiently
and accomplish desired outputs. Specifically, the software is developed
using various programming codes and executed through a computer’s processor.

The software allows hardware devices to communicate and enables users to control inputs and outputs. It helps in the functioning of the hardware in the computer. Also, the software can help users to perform a specific task depending on the type of software. Google Chrome, VLC , Word, Excel are some popular examples of software.

Hardware Vs Software: Key Differences

Let us list down some of the major differences between hardware and
software:

• Hardware refers to the physical components of the computer that are
used to store and execute/run the software, whereas software refers to a set
of instructions given to the computer to control the hardware to perform a
certain task.

• Hardware is categorized into input, output, storage, and external
components. Furthermore, the software is categorized into system software
and application software.

• Hardware usually wears out over time, whereas software does not.
But, the software can face bugs and glitches.

• Hardware cannot be transferred electrically from one place to
another, whereas software can be transferred electrically with network
access.

• Hardware is known to understand only machine-level language. In
contrast, the software takes input in human-readable languages, and then
interprets it in machine-level language and sends it to hardware for further
processing.

• Examples of hardware are the keyboard, mouse, monitor, speakers,
webcam, hard disk, etc. Besides, the examples of software are MS Word,
Excel, Photoshop, Windows OS, Linux, etc.

Difference Between Hardware and Software

Let’s discuss the differences between Hardware and Software side by side
with the help of the following comparison chart (in a tabular form):

Hardware
Software

Hardware refers to the

physical components of a computer

that help to set up a computer system and execute instructions.
Software refers to the

set of instructions

that help users to interact with computer components and instruct the CPU to do the intended or specified tasks.

Hardware devices are

manufactured

using electronic components and other materials.
Software is

written

using various programming languages like Java, Python, etc.

Since hardware is of physical nature, we can

touch and see

the hardware.
Software is not physical in nature and

cannot be touched

. However, it

can be viewed digitally

on a computer.

Hardware is generally classified as

input devices, output devices, storage, and internal components

.
Software is generally classified as

system software and application software

.

Because of its physical nature, hardware

will wear out over time

.
Although the software

doesn’t get damaged physically

, it can get affected due to glitches and bugs.

Hardware

does not get infected

by computer viruses.
Software

can be infected

with computer viruses, malware, Trojan, etc.

If damaged, the hardware can be

physically replaced

with an entirely new component or part.
If infected, the software can be

reinstalled using the installer

or from a backup.

Hardware devices

cannot be moved

from one place to another

electrically

using a network. They must be physically moved.
Software

can be easily transferred

from one computer to another using a network.

Hardware devices help to

process operations at the machine level

.
Software mainly helps to

control the hardware and provide results

based on the task given to the computer.

Hardware is referred to as

tangible

.
Software is said to be

intangible

in the traditional sense. However, it may also be referred to as a tangible asset based on certain accounting standards.

Hardware

failures are usually caused by overheating, dust, etc

.
Software

failures are usually caused by overloading, systematic error, major-minor version error, etc

.

Hardware is

dependent on the software

and starts working after the software is loaded.
Since the software runs on a computer system and controls the hardware components, it cannot function without hardware. Thus, the software is also

dependent on hardware

in some way or the other.

Examples of hardware include

mouse, keyboard, speaker, webcam, scanner, printer, etc

.
Examples of software include

Excel, Word, PowerPoint, VLC, Google Chrome, Microsoft Windows OS, etc

.

What is the main difference between hardware and software?

The fundamental difference between hardware and software is that the
hardware can be referred to as the physical components of a computer system,
while software can be referred to as a set of instructions that instruct a
computer system or hardware components to operate and perform specific tasks
or functions.

Note: Both hardware and software are dependent on each other and are
essential for the proper functioning of the computer system. However, not
all the hardware and software are compulsory.

Understanding Hardware and Software with an Example

System software, such as an operating system, establishes an interface
between computer hardware and the user. The operating system controls all
the basic functions like hardware, memory management, process management,
file management, input-output device management, etc. Using this interface,
users can interact with hardware devices and give instructions to the
system. Users can install specific application software to perform specific
tasks such as
image editing, video processing, opening media files, etc.

There are many examples of both hardware and software. However, we have
discussed some of the most common ones below:

Examples of Hardware

A wide range of hardware is used on computers. The following are some of the
primary types of computer hardware:

•

RAM

: RAM or Random Access Memory is a form of hardware and works as a
computer’s primary memory to temporarily store current data (or ongoing
data) so that it can be easily and quickly accessed by the processor. It is
a

volatile

memory and the data
stored in it is lost when the power supply is disconnected.

•

ROM

: ROM or Read-Only Memory is a

non-volatile

storage medium that
stores essential computer data such as firmware. The data stored in ROM can
only be read and is almost impossible to modify by the user. It keeps the
stored data even after the power is turned off. It gives read-access to the
computer’s processor to write/load boot-up data and system files into
primary memory.

•

CPU

: The CPU or Central Processing Unit is called the brain of the computer.
It is one of the primary components of a computer system and includes the

Control Unit (CU)

and the

Arithmetic Logic Unit (ALU)

. It processes instructions and handles calculations and other logical
operations of the computer. CPU is also known as processor, central
processor, microprocessor, and chip.

•

Motherboard

: The motherboard is the main

printed circuit board (PCB)

in a
computer system. It typically boards most of the important computer
components, including the CPU, RAM, ROM, connectors, and ports for input,
output, and storage devices. It is assembled inside a computer case along
with other electronic chip components.

•

Keyboard & Mouse

: These are the primary input devices that enable users to enter data into
a computer system. The keyboard consists of several keys that help to input
alphabet letters, numbers, signs, and other information. The mouse works
like a point-and-click device, which helps in moving the cursor and
selecting specific objects on the computer’s screen (also called

Monitor

).

In the image above, some other popular hardware devices or components are
displayed.

Examples of Software

A wide range of software is used on computers. The following are the two
main types of software in a computer under which all software can be
classified:

•

System Software

: System software includes the set of core programs and settings that help
operate a computer system. System software primarily manages or controls the
operation of hardware components. Also, it provides a platform to develop
and run application programs. System software is necessary to operate a
computer system. For example,
operating system, device driver, firmware, language translator, etc.

•

Application Software

: Application software includes a set of codes that help users perform
specific tasks using a computer system. It primarily runs in the front-end
and requires a platform designed by the system software. However, the
application software does not replace the system core functions. It is
designed to meet the requirement of users to perform specific tasks like
Photoshop, web browsing, media manager, etc.

In the image above, some popular system software and application software
are displayed. There are many more.
