Hardware & Software Lesson 3 Software KS3 COMPUTING KS3 Computing

Lesson Aims 1 To understand the term Software 2 To understand the terms Operating System, Applications Software and Utilities 3 To be able to list examples of the above

Applications Software 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

What is an Operating System? 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. Providing a user interface Memory management Functions of an OS Peripheral management Multi-tasking Providing basic security

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’.

What is Utility Software? Utilities are small programs that perform maintenance tasks. For example maintaining security.

Below are examples of each type of software Applications 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

3 applications software 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

Write the answer to these questions in your book: Assessment Write the answer to these questions in your book: 1 What is software? [1] 2 What is an operating system? [1] 3 What is applications software? [1] 4 What is utility software? [1] 5 Give two examples of an operating system. [2] 6 Give two examples of applications software. [2] 7 Give one example of a utility. [1] 8 Give one function of an operating system. [1]

Activity 3 Information System You are going to create a simple information system about Software types using Python Look at the example

Creating the welcome message Activity 3a Creating the welcome message

Creating the menu options Activity 3b Creating the menu options

Adding the information Activity 3c Adding the information

name = input(“What is your name? ”) if choice.lower() == “a”: Activity 4 Extension Tasks 1 Name Ask the user their name and use it in the menu options name = input(“What is your name? ”) 2 Case Allow the user to enter upper or lower case answers if choice.lower() == “a”: 3 Sleep Add subtle pauses to your program import time time.sleep(1)
