E-safety

Software piracy is when someone copies or uses software without permission. This is not a good thing and is illegal in the UAE.

This is bad because making apps can sometimes cost a lot of money. So, when a company sells the app, they want to get some money back. Also, some of the money companies get will help make the app better. Most apps are free, but many apps are not.

Using apps like this can also be harmful. Sometimes these apps have viruses in them. They can steal some private information from your phone or computer. Be careful! Do not use pirated software.

Accessibility, ergonomics and learnability of devices.

The evolution and adjustments of products are aimed to try and improve the usability of an object. Usability can be used to describe how easy it is to use an object

Some factors that can improve usability can be physical such as the shape of an object, while others are improved by making it more user-friendly, such as a software update. Devices can be designed to improve their usability under the following headings:

• ergonomics

• accessiblity

• learnability
