The data type Sergio will apply to this set of data that was once restricted to become available to all users is: Public.
A database can be defined as a structured or organized collection of data that are stored on a computer system and usually accessed electronically.
A data type refers to the content of both structured and unstructured data while organizing them into categories based on specific criteria, especially for access or usage, easy retrieval, sorting, and storage by users.
In Computer and technology, the three (3) main data type with respect to restrictions on its access or usage are:
A public data is typically made up of variables that are visible and accessible to all classes or users.
In conclusion, Sergio should make the data a public data, in order to make them available to all users.

Answer:
C. Z-wave
Explanation:
The Z wave is a wireless communications protocol used primarily for automation. The Z- wave operates using a mesh network and then uses low energy radio waves to communicate from appliance to appliance.
The Z wave operates on a lower frequency than most other popular RF devices, thus making interference nonexistent.
The range of the Z-wave is 100m. Hence, it can give a perfect coverage from the base station to the company.
<em>Option A is wrong</em> . This is because the Zigbee is insecure and has a low coverage range (10m-20m). This means that there are possibilities of interference and also improper coverage beyond 50 m.
<em>Option B is wrong.</em> This is because Bluetooth devices are insecure, can loose connections under certain conditions. They have a range of 10m which is a lot lower than 50m benchmark.
<em>Option D is wrong</em>. NFC stands for Near Field Communication. This means its range is practically about 4cm and it cannot be used for long ranges as the company intends.
Answer:
It is supported by many different experiments.
Explanation:
Scientific theory is based on different experiments and tested in different situations and environment will all aspects. If the experiment finds true then observations will become theory. It can be changed in future if it does not meet the newly proposed conditions. But It does not means that, every theory can be changed.
