Answer:
B) wireless local area network (WLAN)
Explanation:
WLAN which fully meaning is WIRELESS LOCAL AREA NETWORK is a network provider that enables two or more mobile phone user , desktop or computer user to connect and have access to the internet by simply connecting to the local area wireless network and this type of wireless network are more cheaper to install.
Example of where WIRELESS LOCAL AREA NETWORK can be found are : School building, Office building, School campus, home, among others.
Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Answer:
A. True
Explanation:
1. I took the test
2. Flash drive ports are connected to the rest of the computer, so putting in an infected flash drive into the port will cause the bug to spread throughout the whole device.
