Answer:
The answer to this question is given below in the explanation section.
Explanation:
First, we need to know what is the graphic user interface (GUI)?
A GUI is a form of user interface that allows the users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of a text-based user interface as in MS-DOS. Users interact through such devices using their icon, navigation using the mouse cursor, etc , and touching. In short, an interface that has graphical options.
so, in the context of the question, the following are examples of GUI.
Virus protection software: Because virus protection software has a graphical interface and user can use it easily by using its graphics and exploration functionality.
Icon: icon is an example of GUI because ICON built on other many graphics parts. In short, the icon is part of the GUI.
The followings are not the example of GUI:
Microphone and USB cord because these are the electronic parts and they don't possess the GUI.
Answer:
Both Technicians are correct.
Explanation:
Remember that Ohm's Law its a relationship between Voltage (E), Current (I) and Resistance (R) in an electrical circuit. This relationship is defined by the following equation:

Each one of the letters could be called a variable. Now, also remember that the number of equations you have is equal to the number of variables unknown you could have.
In Ohm's Law you have 3 variables (E,I,R) and 1 equation. It means that you need to know 2 variables (Whatever 2 variables) to know the third.
Technician A says, in other words, that could calculate the Circuit current flow (I) knowing total circuit resistance (R) and total voltage (E). Note that Technician A knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

Technician B says, in other words, that could determine the unknown resistance (R) knowing total current (I) and source voltage (E). Once again, note that Technician B knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

It is concluded that both technicians are right.
Answer:
An operating system is a software that helps the any computers basic needs or functions. For example, the windows on a computer is a operating system.
