A already assigned variable cannot be assigned twice You can make the variable change over to a new one or call a whole new one to assign one without a value or It might be possible to do v=n (v is variable and n is number / value)
The connector for ethernet cables is called RJ45. for phone jack is RJ11. Although they look the same, the RJ11 has only 4 leads, as opposed to 9 leads in RJ45. Also, RJ11 is not as wide as RJ45, so the connector does not fit.
Even if it would, the signals would be totally incompatible, so no success can be expected.
The correct option to this question is class interface.
The class interface is the portion of a class that is visible to the application’s programmer. Class interfaces mean implementation of public methods of the class. These class interfaces of the class are easily visible to the application’s program either the one who is developing the application program or the one who is reading the application’s code.
Class interface can be seen by the other classes as its public face. Class interfaces separate the class’s implementation and its interaction with other classes. That way the implementation of the class can be modified easily without being known by other classes. Basically, the programmer who is developing the program, all the portions of the programm is visible to that programmer.
For example, the class is written below:
class class-name
{
private members;
public method()
{
//method defination
}
}
when the class object is created, the code of the object to the programmer is visible.
<u>While the other options are incorrect:</u>
- Form: the form is used to collect information from the user. It can be build using front-end development tools
- Design: Design is a term used in computer or software engineering to make something from scratch or beginning. It can be methodologies, standards, or techniques etc.
- Control: Control is the mechanism or a term used in software development to control the program or execution of the program.
