A technician a mobile device that has no sound. A technician should check If the volume is muted first.
Explanation:
- Improper audio settings in your computer can also cause your speakers plugged in but no sound. So you should check the following audio settings to fix your sound problem.
- An on-screen display appears with incall options. Tap the Mute icon. A microphone icon with a diagonal line through it.
- Just restart your phone as usual to refresh the device.
- Disable Bluetooth on your phone. Sometimes the Bluetooth feature would result in the speaker problem so here you are able to navigate to Settings> Bluetooth to switch off the feature to settle the problem.
- The earpiece may be damaged. This is because the dedicated noise canceling mic is damaged.
- You might have the sound muted or turned down low in the app. Check the media volume if nothing works out.
Answer:
C. sqrt(Math)
Explanation:
All but one of options A to E are is not a static method.
Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;
The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.
Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.
The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
Validation: Understanding and showing acceptance for another person
Answer:
A. Supercomputer
Explanation:
An embedded computer is a very small computer or processor that is installed to drive control other systems with the focus on performing one specific task.
Desktop computers, as the name implies, are mounted on desks, inexpensive and fast computational devices.
The mainframe a very large and expensive computers used by companies to run many applications or computations at a time, while supercomputers are similar but runs very few programs at a time.
ICT Systems is made up of these components:
1: Hardware's - Physical Components in a computer or peripheral's
2. Data - Raw facts/figures/statistics
3. Software's - names of computer programs
4 People (that makes and used the above listed.).: Entering data by many different means, examples, keyboard, or voice recognition
5. Procedures: Actions conducted in a series of a certain order to ensure the system will run smoothly.
Sometimes, it enlists Internet as it assists in the form of connectivity and communication.
Types:
There are several types you could described, But, the main types are:
1. Information Systems: Converted data which gives it meaning
2. Control Systems
3. Communication Systems
Input and Output in the context of these three works and relies mostly on the GIGO Concept.
Hope this helps
