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

10. 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.
