c.
What is the difference between software and hardware?
|
Hardware |
Software |
|
Hardware
refers to the physical components of a computer system. |
Software
is a set of digital instructions or programs that tell the hardware what to
do. |
|
These
are tangible, i.e. you can touch, see, and physically handle them. |
It
is intangible, meaning you cannot physically touch it. Software exists in the
form of code, which is stored electronically and executed by the hardware. |
|
Examples
include the monitor, keyboard, CPU, and hard drive. |
Examples
includes system software, application software, programming software |
d.
Name any two categories of software.

e.
What are the main functions of software in a computer system?
·
To
control and manage hardware.
·
To
perform specific user tasks.
·
To
help in processing and storing data.
f.
What is system software? Provide an example.
System
software is software that manages and controls the hardware so other software
can work.
Example: Operating System like Windows.
g.
Define application software and give two examples.
Application
software helps users perform specific tasks.
Examples: Microsoft Word, Adobe Photoshop
h.
What is utility software? Provide two examples.
Utility
software helps maintain, analyze, and optimize a computer.
Examples: Antivirus, Disk Cleanup Tool
i.
Differentiate between system software and application software.
|
System Software |
Application Software |
|

with the system. |
Runs when the user opens it
manually |
|
Examples: Windows, Linux, device
drivers |
Examples: MS Word, Google Chrome,
Photoshop |
j.
What is open-source software (OSS)? Name any two popular open-source software
programs.

Answer Questions:
a.
Explain the term "software" in detail. How does it differ from
hardware, and why is it essential for computer systems?
Software
refers to the set of instructions, programs, and data used to operate computers
and perform tasks. It tells the computer what to do and how to do it.
Difference
from Hardware:
Software
is intangible (cannot be touched), while hardware is the physical part of a
computer.
Without
software, hardware cannot function.
Importance:
·
It
runs the operating system and all applications.
·
It
enables users to perform tasks like writing, drawing, or playing games.
·
It
manages all the hardware resources effectively.
b.
What are the different types of software? Explain system software, application
software, and utility software with examples.
There
are three main types of software:
System
Software:
Controls
and manages hardware.
Example:
Operating System (Windows, Linux), Device Drivers.
Application
Software:
Helps
users do specific tasks.
Example:
