What is Software?
Software is a computer program that provides the
computer with a set of instructions telling the computer
what to do and how to do it.
There are three types of Software:
1
Operating Systems
2
Applications Software
3
Utilities
Operating Systems
What is an Operating System?
The operating system (OS) is a crucial piece of software in a computer system because it provides a platform on which
all other programs can run.
Functions of an OS
Providing a user interface
Memory management
Peripheral management
Multi-tasking
Providing basic security
Applications Software
What are Applications Software?
Applications are programs designed to help the user carry out specific tasks or something useful, for example
writing a letter or designing a website.
Recently started becoming known as ‘Apps’.
Utility Software
What is Utility Software?
Utilities are small programs that perform maintenance tasks.
For example maintaining security.
Examples
Below are examples of each type of software
Operating Systems
Applications Software
Utilities
Windows
Mac OS X
Linux
Word Processors
Spreadsheets
Databases
Graphics Design
Email Clients
Internet Browsers
Web Design
Desktop Publishing
Anti-Virus
Device Drivers
Backup Software
Disk Repair
Activity 1
Sort the following software into the correct category
Operating System
Applications Software
Utility
Activity 2
Scenario
You are going to add information about the software you recommend to your school presentation.
Each software recommendation must be accompanied with a suitable reason (2-3 sentences) and an image
representing it (why have you chosen it, what does it allows you to do in a school environment?).
You must recommend:
- 1 operating system
- 3 applications software
- 2 utilities
Operating System
Recommendation
Windows 10
Reason
This is the most common operating
system in the world.
This means:
- Most apps the school wants to
use will work with it;
- Students will more likely be
familiar with it so already know
how to use it.
Example slide

Activity 3
Information System
You are going to create a simple information system about Software types using Python
Look at the example
Activity 3a
Creating the welcome message
Activity 3b
Creating the menu options
Activity 3c
Adding the information
Activity 4
Extension Tasks
Ask the user their name and use it in the menu options
1
Name
name = input(“What is your name? ”)
Allow the user to enter upper or lower case answers
2
3
Case
Sleep
if choice.lower() == “a”:
