Answer: VSAT(Very Small Aperture Terminal)
Explanation:
The computer system could be connected to the transceiver via an antenna and can send and receive data.
Using satellite communication the data could be send to the end user.
Answer:
Option (D) using the private access specifier on the class fields
Explanation:
- The private access modifier can be used to hide the data.
- Methods and data variables ( fields ) can be declared with the private access modifier.
- Data hiding is a OOPS Concept which can be achieved with the private keyword (private access modifier).
- The access modifiers are of types Public, Private, Protected and Default ( no access modifier - no need to explicitly specify the default keyword).
- Data hiding means to hide the data, the data is contained in the class variables.So, option (d) using private access modifier on the class fields is correct option.
- Option (A) is wrong as the using the public access modifier doesn't hide anything. It is public and is visible to the public.
- Option (B) is wrong as using the private access modifier on the methods means it is hiding the implementation of the methods not the data.
- Option (C) is wrong as using private access modifiers on class definition means making the classes not visible to other classes it doesn't mean data hiding as the data is contained in the class variables.
Answer:
- Boolean------------------->Stores one of two given values
- null------------------->allows optional values
- memo------------------->allows inserting a large amount of text including numbers
- autonumber------------------->serves as a counter in your database
Explanation:
<em>Boolean:</em> In computing the Logical or Boolean data type is one that can represent binary logic values, that is, 2 values, which normally represent false or true.
<em></em>
<em>Null:</em> Null is not designed as an integer, character, or other specific data type.
<em>Memo:</em> It is used to enter data that includes text, numerical values that don't require mathematical calculations, or a combination of text and numbers. Accepts a maximum of 255 characters.
<em>Autonumber: </em>The value that this field contains will be increased every time a record is added to the table that contains it, then this data type is used to carry a sequence of the records entered into a table. This type of data is not allowed to be modified.
