A) Delete the desktop shortcut to the app.
B) Uninstall the app.
C) Delete the app's installed files.
D) Remove all files created by that app.

Accepted Answer

The first step in removing an app you no longer need from your computer is to uninstall it. This will remove the app from your system and also remove any associated files that were installed with it. Deleting the desktop shortcut or individual files related to the app will not remove it completely from your system. Deleting all files created by the app would be difficult and time-consuming, and may also remove files that are still useful or necessary for other programs.

Question 2

Aidan pays a fee every six months to use a music streaming app with no advertisements. What type of app is this?
A) SaaS
B) Shareware
C) Open source
D) Freeware

Accepted Answer

This app is a Software-as-a-Service (SaaS) because the user pays a fee every six months to access the service. SaaS is a model of software delivery where users access software through a subscription, and the provider hosts and manages the app on their own servers. In this case, the music streaming app provider is hosting the app on their servers and charging the user for access to the software.

Question 5

Alyssa purchased and installed a photo editing app on her home desktop computer. She also needs to use the app at work and wants to install a copy on her laptop. How can she determine whether this is legal?
A) Consult with a digital rights lawyer.
B) Ask a coworker if he's done the same thing.
C) Look up copyright laws for her state on the Internet.
D) Read the terms of the license agreement.

Accepted Answer

The best option is to read the terms of the license agreement that came with the photo editing app. This will outline the specific conditions under which the app can be used and whether it can be installed on multiple devices. Consulting with a digital rights lawyer may be an option but is likely to be expensive, while asking a coworker is not a reliable method to ensure legality. Looking up copyright laws may provide general information but may not be specific to the particular software being used.
