Answer: B) Install an addition memory card to the current drive
Explanation: Drive storage space is space that has particular capacity to store files and data. If the storage reaches the capacity,it turns out that more space is required for the data storage. The hard drive is a major storage space in a system with large capacity. So, if it gets full, there are various ways it could be increased such as replacing it with other internal hard drive, external hard drive etc.
But installation of the memory card is not the solution for increasing the space because they don't have very large space and can only support small devices.
Answer:
Following are the statement which is given below:
if (gpa > 3.5) // check the condition if gpa exceeds 3.5.
{
deansList++; // increment of 1 in the deansList variable
cout << studentName; // display the studentName,
}
Explanation:
The description of the statement
- In the if statement we check the condition of "gpa" .if "gpa" is greater then 3.5 then it executed the statement inside the if block otherwise nothing will be executed.
- if control moves to the if part it adds to 1 to the deansList.
- Finally, display the value of studentName.
Answer:
False
Database management systems are expected to handle binary, unary and ternary relationships.
Explanation:
Unary Relationship: It is a recursive relationship which includes one entity in a relationship which means that there is a relationship between the instances of the same entity. Primary key and foreign key are both the same here. For example a Person is married to only one Person. In this example there is a one-to-one relationship between the same entity i.e. Person.
Binary Relationships: It is a relationship involving two different entities. These two entities identified using two relations and another relation to show relationship between two entities and this relation holds primary keys of both entities and its own primary key is the combination of primary keys of the both relations of the two entities. For example Many Students can read a Book and many Books can be obtained by a Student.
Ternary Relationships: is a relationship involving three entities and can have three tables. For example a Supplier can supply a specific Part of many Mobiles. Or many Suppliers may supply several Parts of many Mobile models.
