5/1. GitHub is a version control system that allows you to develop applications and generate code. The advantage of using it is that groups can be made, that means, X number of people (collaborators) can carry out an application at the same time, so if they are well synchronized, that time is saved, since the code does not have to be carried out exclusively by one person. In addition, after generating the code and verifying that it works, it can be updated. This means it allows the code of that app to be up to date in a "cloud" and can be downloaded from any computer and continue working.

A printer is a device for obtaining paper documents from a computer.
Here are the guidelines for finding which printer is the best for
you.
The best printer depends on the intended use you will give it. In
spite of the cheap laser printing technology generally, it is more
common to find an inkjet printer with a lot of functions cheaper
than a laser one.
If we are going to use the printer just twice in our life, the best
decision would be an inkjet printer. If our domestic use is going to
be continuous or intensive, or for example, we will use it at the
office, the best option is a laser printer.But, if we are going to
work with pictures, inkjet printer is more professional.
